QUESTION

How to handle custom GraphQL error such that it does not display the exception stack trace in Java

Asked 2022-Mar-24 at 08:19

I have created a simple GraphQL endpoint using Spring Boot and I am using DefaultGraphQLErrorHandler() to handle GraphQL errors.

However, when I throw a custom Exception from my application, the error response which GraphQL produces contains Exception stack trace which is giving away too much information. I want to prevent this.

{
"data": {
    "CommercialAsset": null
},
"errors": [
    {
        "message": "Exception while fetching data (/CommercialAsset) : Asset not fround in Data source",
        "path": [
            "CommercialAsset"
        ],
        "exception": {
            "cause": null,
            "stackTrace": [
                {

                    "moduleVersion": null,
                    "methodName": "getAssetById",
                    "fileName": "CommercialAssetDremioRepositoryImpl.java",
                    "lineNumber": 49,
                    "className": "com.dell.dremioclient.repository.impl.CommercialAssetDremioRepositoryImpl",
                    "nativeMethod": false
                },
                ...
                {
                    "classLoaderName": null,

        },
        "locations": [
            {

            }
        ],
        "extensions": null,

    }
]

}

GraphQL dependency versions that I am using :

    <dependency>
       <groupId>com.graphql-java</groupId>
        <artifactId>graphql-spring-boot-starter</artifactId>
        <version>5.0.2</version>
    </dependency>
    <dependency>
        <groupId>com.graphql-java</groupId>
        <artifactId>graphql-java-tools</artifactId>
        <version>5.2.4</version>
    </dependency>
    <dependency>
        <groupId>com.graphql-java</groupId>
        <artifactId>graphiql-spring-boot-starter</artifactId>
        <version>5.0.2</version>
    </dependency>

Is there any way I can do it using Custom error handler? Something like this -

public class CustomGraphqlErrorHandler implements GraphQLErrorHandler {

@Override
public List<GraphQLError> processErrors(List<GraphQLError> errors) {
    
    List<GraphQLError> errorList = new ArrayList<>();
    
    errors.stream()
            .forEach( e -> {
                if(this.isServerError(e)) {
                    GraphqlDremioClientException gexp = new GraphqlDremioClientException(e.getMessage());
                    gexp.setStackTrace(null); /* This causes failure Bad POST request: parsing failed
                                                 java.lang.NullPointerException: null
                                                 at java.base/java.lang.Throwable.setStackTrace(Throwable.java:865) */
                    errorList.add(gexp);
                } else {
                    errorList.add(e);
                }
            });
    
    return errorList;
}

private boolean isServerError(GraphQLError error) {
    return (error instanceof ExceptionWhileDataFetching || error instanceof Throwable);
}

@Override
public boolean errorsPresent(List<GraphQLError> errors) {
    return !CollectionUtils.isEmpty(errors);
}

}

Answered 2022-Mar-24 at 08:19

I wanted to prevent GraphQL to show stack trace in the error response. One simple solution to it was to add a custom GraphQL error handler to handle the exceptions thrown from my services. I then, created a custom Exception class which could enable or disable stack trace during construction.

Custom Exception class:

public class GraphqlDremioClientException extends RuntimeException implements GraphQLError {

    private static final long serialVersionUID = 1L;
    
    private final String message;
    
    private boolean writeStacktrace = false;

    @Override
    public String getMessage() {
        return message;
    }
    /* other constructors */
        
    public GraphqlDremioClientException(String message, boolean writeStacktrace) {
        super(message, null, false, writeStacktrace);
        this.writeStacktrace = writeStacktrace;
        this.message = message;
    }
    
    public GraphqlDremioClientException(String message, Exception ex) {
        super();
        this.message = message;
    }

    @Override
    public List<SourceLocation> getLocations() {
        return null;
    }

    @Override
    public ErrorType getErrorType() {
        return null;
    }       
}

Custome GraphQL error handler:

@Slf4j
@Component
public class CustomGraphqlErrorHandler implements GraphQLErrorHandler {

    @Override
    public List<GraphQLError> processErrors(List<GraphQLError> list) {
        return list.stream().map(this::getNested).collect(Collectors.toList());
    }
    
    private GraphQLError getNested(GraphQLError error) {
        log.error(error.getMessage(), error);
        
        if (error instanceof ExceptionWhileDataFetching) {
            ExceptionWhileDataFetching exceptionError = (ExceptionWhileDataFetching) error;
            if (exceptionError.getException() instanceof GraphQLError) {
                return new GraphqlDremioClientException(exceptionError.getMessage(), false);
            }
        }
        return error;
    }
}

The error response now:

{
    "data": {
        "CommercialAsset": null
    },
    "errors": [
        {
            "cause": null,
            "stackTrace": [],
            "message": "Exception while fetching data (/CommercialAsset) : Asset not fround in Data source",
            "writeStacktrace": false,
            "locations": null,
            "errorType": null,
            "path": null,
            "extensions": null,
            "suppressed": [],
            "localizedMessage": "Exception while fetching data (/CommercialAsset) : Asset not fround in Data source"
        }
    ]
}

QUESTION

Spring Boot GraphQLQueryResolver won't run, runs on test project

Asked 2022-Feb-09 at 10:11

So I'm new into GraphQL and i got stuff running by manually setup a schemaparser and datafetchers. But I want to refactor and try out by implementing GraphQLQueryResolver to a class and controll my queries from there.

I get it to work by making a new project, but with the same dependencies and should be same implementation, It doesn't run. When I delete the query-methods which reflects the schema, I'll get the error that I need to add methods based on the Queries in the schema, so I get the confirmation it reaches the class-file with the implementation of the GraphQLQueryResolver. But I still get this error when i add the rights methods:

-- Solved --

So I ran my default project on Spring Boot 2.7.0 and 2.6.3 on my test project. When I changed to 2.6.3 on default, it ran. So it seems like the latest GrahpQL isn't fully compatible with Spring Boot 2.7.0 yet. Which might be obvious because it was released in the last month.

QUESTION

graphql-spring-boot-starter Application with only websockets

Asked 2021-Nov-10 at 14:48

I am building a graphql application with spring-boot-starter-webflux 2.5.6 and com.graphql-java-kickstart:graphql-spring-boot-starter:12.0.0. At this point the application is running fine since com.graphql-java-kickstart is easy to start with. With http-Requests I can call Queries and run Mutations and I am even able to create and get updates via Subscriptions over websockets.

But for my application Queries and Mutations also have to run via websocket.

It seems that in com.graphql-java-kickstart:graphql-spring-boot-starter you can only configure a subscription endpoint as websocket. Adding an additional websocket via 'extends Endpoint' and '@ServerEndpoint' did nothing at all.

I also tried to add my own HandlerMapping:

@PostConstruct
public void init()
{
    Map<String, Object> map = new HashMap<String, Object>(
            ((SimpleUrlHandlerMapping) webSocketHandlerMapping).getUrlMap());
    
    map.put("/mysocket", myWebSocketHandler);
    //map.put("/graphql", myWebSocketHandler);

    ((SimpleUrlHandlerMapping) webSocketHandlerMapping).setUrlMap(map);
    ((SimpleUrlHandlerMapping) webSocketHandlerMapping).initApplicationContext();

}

This seems to work with the /mysocket Topic but how do I enable it for /graphql, it seems like there is already a handler listening on:

WARN 12168 --- [ctor-http-nio-2] notprivacysafe.graphql.GraphQL : Query failed to parse : ''

And how to connect the websocket with my GraphQLMutationResolvers?

ANSWER

Answered 2021-Nov-10 at 14:48

My entry point to a solution for this problem was to create a RestController and connect the ServerWebExchange to a WebSocketHandler in the WebSocketService like this:

@RestController
@RequestMapping("/")
public class WebSocketController
{

    private static final Logger logger = LoggerFactory.getLogger(WebSocketController.class);

    private final GraphQLObjectMapper objectMapper;

    private final GraphQLInvoker graphQLInvoker;

    private final GraphQLSpringInvocationInputFactory invocationInputFactory;

    private final WebSocketService service;

    @Autowired
    public WebSocketController(GraphQLObjectMapper objectMapper, GraphQLInvoker graphQLInvoker,
            GraphQLSpringInvocationInputFactory invocationInputFactory, WebSocketService service)
    {
        this.objectMapper = objectMapper;
        this.graphQLInvoker = graphQLInvoker;
        this.invocationInputFactory = invocationInputFactory;
        this.service = service;
    }

    @GetMapping("${graphql.websocket.path:graphql-ws}")
    public Mono<Void> getMono(ServerWebExchange exchange)
    {
        logger.debug("New connection via GET");
        return service.handleRequest(exchange,
                new GraphQLWebsocketMessageConsumer(exchange, objectMapper, graphQLInvoker, invocationInputFactory));
    }

    @PostMapping("${graphql.websocket.path:graphql-ws}")
    public Mono<Void> postMono(ServerWebExchange exchange)
    {
        ...
    }

}

In this prototype state the WebSocketHandler is also implementing the Consumer which is called to handle each WebSocketMessage:

public class GraphQLWebsocketMessageConsumer implements Consumer<String>, WebSocketHandler
{

    private static final Logger logger = LoggerFactory.getLogger(GraphQLWebsocketMessageConsumer.class);

    private final ServerWebExchange swe;

    private final GraphQLObjectMapper objectMapper;

    private final GraphQLInvoker graphQLInvoker;

    private final GraphQLSpringInvocationInputFactory invocationInputFactory;

    private final Sinks.Many<String> publisher;

    public GraphQLWebsocketMessageConsumer(ServerWebExchange swe, GraphQLObjectMapper objectMapper,
            GraphQLInvoker graphQLInvoker, GraphQLSpringInvocationInputFactory invocationInputFactory)
    {
        ...
        publisher = Sinks.many().multicast().directBestEffort();
    }

    @Override
    public Mono<Void> handle(WebSocketSession webSocketSession)
    {
        Mono<Void> input = webSocketSession.receive().map(WebSocketMessage::getPayloadAsText).doOnNext(this).then();
        Mono<Void> sender = webSocketSession.send(publisher.asFlux().map(webSocketSession::textMessage));
        return Mono.zip(input, sender).then();
    }

    @Override
    public void accept(String body)
    {
        try
        {
            String query = extractQuery(body);
            if(query == null)
            {
                return;
            }
            GraphQLRequest request = objectMapper.readGraphQLRequest(query);
            GraphQLSingleInvocationInput invocationInput = invocationInputFactory.create(request, swe);
            Mono<ExecutionResult> executionResult = Mono.fromCompletionStage(graphQLInvoker.executeAsync(invocationInput));
            Mono<String> jsonResult = executionResult.map(objectMapper::serializeResultAsJson);
            jsonResult.subscribe(publisher::tryEmitNext);
        } catch (Exception e)
        {
            ...
        }
    }

    @SuppressWarnings("unchecked")
    private String extractQuery(final String query) throws Exception
    {
        Map<String, Object> map = (Map<String, Object>) objectMapper.getJacksonMapper().readValue(query, Map.class);
        ...
        return queryPart;
    }

    @Override
    public List<String> getSubProtocols()
    {
        logger.debug("getSubProtocols called");
        return Collections.singletonList("graphql-ws");
    }

}

This solution does not yet touch security aspects like authentication or session handling.

QUESTION

Spring Boot application failed to start when using GraphQL Java Tools

Asked 2021-Oct-08 at 21:14

I just setup a new Spring Boot application with GraphQL Java Tools. The precise versions in my Maven pom.xml file are:

com.graphql-java-kickstart:graphql-spring-boot-starter:12.0.0
com.graphql-java-kickstart:graphiql-spring-boot-starter:11.1.0
com.graphql-java-kickstart:graphql-java-tools:12.0.0

Although my application compiles, when I start my Spring Boot application, it fails with the following cryptic error:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    graphql.kickstart.tools.resolver.FieldResolverScanner.findResolverMethod(FieldResolverScanner.kt:92)

The following method did not exist:

    'java.lang.String kotlin.text.CharsKt.titlecase(char)'

The method's class, kotlin.text.CharsKt, is available from the following locations:

    jar:file:/C:/Users/c-martind/.m2/repository/org/jetbrains/kotlin/kotlin-stdlib/1.3.61/kotlin-stdlib-1.3.61.jar!/kotlin/text/CharsKt.class

It was loaded from the following location:

    file:/C:/Users/c-martind/.m2/repository/org/jetbrains/kotlin/kotlin-stdlib/1.3.61/kotlin-stdlib-1.3.61.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of kotlin.text.CharsKt

I am using Java instead of Kotlin so I don't know why it's having an issue with Kotlin.

ANSWER

Answered 2021-Oct-08 at 21:14

As per GraphQL Java Tools's README you need to set the Kotlin version in your <properties> section in your Maven pom.xml file:

<properties>
    <kotlin.version>1.5.0</kotlin.version>
</properties>

If you're using graphl-java-tools with Spring Boot you may run into Kotlin version mismatches because both depend on Kotlin. Specifically, Spring Boot Starter may override the version with a version lower than required by GraphQL Java Tools. Setting the above property will bump the Kotlin version to the appropriate version. If you don't override this version you will run into an error like NoClassDefFoundError or the one you encountered during application startup.

GraphQL Input type declaration for Mutation

Asked 2021-Oct-05 at 15:36

I'm new to GraphQL and after some coding I bumped into a problem with declaring an Input type for a Mutation. Here's my Schema:

type Test {
  id: ID!
  label: String!
}

extend type Query {
  test(id : ID!): Test
  listTests (where: myWhereCondition, orderBy: myOrderByCondition): [Test!]!
}

extend type Mutation {
  createTest(label: String!, testTypes: TestTypesInput): Test!
}

input TestTypesInput {
  testTypes: [IdInput]
}

input IdInput {
  id: ID!
}

When I run my app, I get the error

Caused by: graphql.kickstart.tools.SchemaError: Expected type 'IdInput' to be a GraphQLInputType, but it wasn't! Was a type only permitted for object types incorrectly used as an input type, or vice-versa? at graphql.kickstart.tools.SchemaParser.determineType(SchemaParser.kt:400) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.SchemaParser.determineInputType(SchemaParser.kt:417) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.SchemaParser.determineInputType(SchemaParser.kt:410) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.SchemaParser.createInputObject(SchemaParser.kt:179) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.SchemaParser.parseSchemaObjects(SchemaParser.kt:79) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.SchemaParser.makeExecutableSchema(SchemaParser.kt:112) ~[graphql-java-tools-11.0.1.jar:na] at graphql.kickstart.tools.boot.GraphQLJavaToolsAutoConfiguration.graphQLSchema(GraphQLJavaToolsAutoConfiguration.java:143) ~[graphql-kickstart-spring-boot-autoconfigure-tools-11.1.0.jar:na]

I can't understand what I'm missing, to me the "IdInput" is well declared as input and reading some other examples it looks correct to me, but it clearly isn't. I tried to declare che IdInput as type insted of input, but it obviously doesn't work. How can I pass a list of input objects into an input array? If you need more informations I'll add them, at the moment I'm just mixing some declaration to come up with the correct one, with no success. Thank you in advance for your help!

Find out this was a misleading error, since the GraphQL schema couldn't fetch with the Mutation Resolver's signature method. Instead of pointing out that part, it kept to break in the GraphQL Schema declaration. Once declared the signature method accordingly to the Schema, everything worked out like a charm. Hope it may help someone with this misleading error handling.

QUESTION

GraphQL subscription with Jetty 10 embedded

Asked 2021-Sep-16 at 12:40

My objective is to have a functional version of the latest Graphql-java mixed with jetty version 10.

I have done a lot of tests, using different methods, and now I am stuck with the difference of the WebSocket implementation (on Jetty) between the version 9.4 and 10.0.6.

To test the implementation I am working on the example from the graphQL repository sample.

My tests are on the subproject servlet-hello-world, where a simple graphQL subscription is done and working on jetty 9.4

I have updated gradle to use the latest version

def jettyVersion = '9.4.43.v20210629'

dependencies {
    implementation "com.graphql-java-kickstart:graphql-java-servlet:$LIB_GRAPHQL_SERVLET_VER"
    implementation "io.projectreactor:reactor-core:3.4.9"
    implementation 'ch.qos.logback:logback-classic:1.2.5'
    implementation 'org.slf4j:slf4j-simple:2.0.0-alpha4'
    implementation "org.eclipse.jetty:jetty-webapp:${jettyVersion}"
    implementation "org.eclipse.jetty:jetty-annotations:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:websocket-api:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:websocket-server:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:javax-websocket-server-impl:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:websocket-common:${jettyVersion}"
}

def jettyVersion = '10.0.6'

dependencies {
    implementation "com.graphql-java-kickstart:graphql-java-servlet:$LIB_GRAPHQL_SERVLET_VER"
    implementation "io.projectreactor:reactor-core:3.4.9"
    implementation 'ch.qos.logback:logback-classic:1.2.5'
    implementation 'org.slf4j:slf4j-simple:2.0.0-alpha4'
//    implementation "org.eclipse.jetty:jetty-webapp:${jettyVersion}"
//    implementation "org.eclipse.jetty:jetty-annotations:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:websocket-jetty-api:${jettyVersion}"
    implementation "org.eclipse.jetty.websocket:websocket-jetty-server:${jettyVersion}"
//    implementation "org.eclipse.jetty.websocket:javax-websocket-server-impl:${jettyVersion}"
//    implementation "org.eclipse.jetty.websocket:websocket-common:${jettyVersion}"
}

Then I am stuck on the changes in the API where the WebSocketServletContainerInitalizer is replaced by JettyWebSocketServletContainerInitializer:

    var server = new Server();
    var connector = new ServerConnector(server);
    connector.setPort(PORT);
    server.addConnector(connector);

    var context = new ServletContextHandler(ServletContextHandler.SESSIONS);
    context.setContextPath("/");
    context.addServlet(HelloServlet.class, "/graphql");
    server.setHandler(context);

    WebSocketServerContainerInitializer.configure(
        context,
        (servletContext, serverContainer) ->
            serverContainer.addEndpoint(
                ServerEndpointConfig.Builder.create(SubscriptionEndpoint.class, "/subscriptions")
                    .configurator(new GraphQLWSEndpointConfigurer())
                    .build()));

    server.setHandler(context);

    server.start();
    server.dump(System.err);
    server.join();
  }

The difference is the configurator that has changed the type of the configurator from ServletContainer to a JettyWebSocketServerContainerand there is no addEndpoint method anymore to connect my SubscriptionEndpoint to.

I have absolutely no clue how to connect my GraphQLWebsocketServlet.

The old version of Jetty was websocket implementation neutral (core, javax.websocket, jetty native websocket, etc). That proved to be too complex when multiple implementations were being used at the same time.

The new Jetty 10+ implementation requires you to use the appropriate <Impl>WebSocketServletContainerInitializer for the implementation you are using. (where <Impl> is one of Javax, Jakarta, or Jetty)

Since it looks like you are using javax.websocket, here's the appropriate class to use.

JavaxWebSocketServletContainerInitializer.configure(context, (servletContext, wsContainer) ->
{
    // This lambda will be called at the appropriate place in the
    // ServletContext initialization phase where you can initialize
    // and configure  your websocket container.

    // Configure defaults for container
    wsContainer.setDefaultMaxTextMessageBufferSize(65535);

    // Add WebSocket endpoint to javax.websocket layer
    wsContainer.addEndpoint(
        ServerEndpointConfig.Builder.create(
            SubscriptionEndpoint.class, "/subscriptions")
            .configurator(new GraphQLWSEndpointConfigurer())
        .build());
});

QUESTION

Should multi-threading always be used in GrpahQL's DataFetcher?

Asked 2021-Sep-05 at 17:48

I am using GraphQL java implementation.

Although one of GraphQL's strengths is fetching different fields in parallel, I found that only one thread is in use if I do not use multi-threading methods like CompletableFuture in DataFetchers.

So my question is, should I always use multi-threading in DataFetcher as shown below in the official doc, even if it is just fetching from one source (a database for example) instead of multiple sources?

It seems that this is the recommended approach and will do no harm at least.

But I would like to hear from more experienced devs.

Thanks in advance!

In graphql-java implementation by default, all the resolver is called sequentially.

Consider below schema

type Query {
 allPost: [Post!]
}

type Post {
  id: ID!
  tittle: String!
  postDetail: PostDetail!
  comments: [Comments!]
}

type PostDetail {
  id: ID!
  # This can be converted into enum
  postMediaType: String! 
  postUrl: String!
}

type Comment{
 id:ID!
 name: String!
 description: String!
}

And this is the query over the schema given above

{
  allPost{
    id
    tittle
    postDetail {
     id
     postMediaType
     postUrl
    }
    comments{
     id
     name
     description
    }
  }
}

When the server will execute this query first Post resolver will be called and if Post resolver does not returns comments or postDetail data then graphQL will try to search for there respective resolvers if it does not find it the server will fail during boot up.

Now graphQL server will first call the PostDetail resolver and it will wait for its completion and then it will call Comments Resolver to get the list of all the comments for that post.

As we can see resolvers are called sequentially even though PostDetail resolver and Comments resolver does not depend on each other. This is where we can use CompletableFuture to make the PostDetail resolver and Comments resolver asynchronous.

In this case first Post resolver will be called after that graphql will call PostDetail resolver which will return CompletableFuture and then it will call Comments resolver which will also return CompletableFuture and later when both of these future will complete it will send a response back to the client.

So it does not depend upon the number of Datasource you have GraphQL does not care about different types of data sources it just cares about the wiring of Datafecters for the type/field.

You can run your resolvers in parallel if there is no dependency between them.

QUESTION

BigDecimal not present when resolving type

Asked 2021-Aug-26 at 04:31

I'm "up the middle" Spring Boot 2.5.4 with graphql-java-16.2 brought in via some org.springframework.experimental/graphql-spring-boot-starter dependency. The GraphQL Java Documentation suggests that I can just BigDecimal something up in my Schema: https://www.graphql-java.com/documentation/v16/scalars/

...
type TemplateLineItemAction {
    type: String!
    quantity: BigDecimal!
}
...

The runtime begs to differ. The operative portion of the giant stacktrace is...

...SchemaProblem{errors=[The field type 'BigDecimal' is not present when resolving type 'TemplateLineItemAction' [@5:1]]}...

I tried just adding scalar BigDecimal to the schema.graphqls file to no avail; same stacktrace.

The pom.xml is like...

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.experimental</groupId>
            <artifactId>graphql-spring-boot-starter</artifactId>
            <version>1.0.0-M1</version>
        </dependency>

Note the graphql-spring-boot-starter starter comes by way of Spring (org.springframework.experimental/graphql-spring-boot-starter), not com.graphql-java/graphiql-spring-boot-starter, which is where many google results point me. It really shouldn't matter, that BigDecimal mapping is supposed to be a function of graphql-java-16.2. But, who knows?

That starter brought in...

I can see it has some GraphQLScalarType...

    public static final GraphQLScalarType GraphQLBigDecimal = GraphQLScalarType.newScalar()
            .name("BigDecimal").description("Built-in java.math.BigDecimal").coercing(new GraphqlBigDecimalCoercing()).build();

... along with some deprecation that it may move someday, but its there now: https://github.com/graphql-java/graphql-java/blob/v16.2/src/main/java/graphql/Scalars.java#L108. I just can't figure out how to use it.

What do I have to do in my schema.graphqls file or project to get to use BigDecimal on my GraphQL Types?

QUESTION

Schema input type always "LinkedHashMap cannot be cast..."

Asked 2021-Aug-24 at 11:35

My schema.grapqls looks like...

scalar BigDecimal
...
input TemplateLineItemInput {
    partMasterId: String!
    partMasterIdPath: String!
    actionType: String!
    actionQuantity: BigDecimal!
}
...
type Mutation {
    ...
    createLineItem(id: ID! input: TemplateLineItemInput!): TemplateBom
}

My POJOs are all Lombok-ie and were working great until I tried to create that input.

import lombok.Builder;
import lombok.Data;

import java.math.BigDecimal;

@Data
@Builder
public class TemplateLineItemInput {
  private final String partMasterId;
  private final String partMasterIdPath;
  private final String actionType;
  private final BigDecimal actionQuantity;
}

I believe I have the mutation it wired up correctly...

@Component
public class TemplateBomDataWiring  implements RuntimeWiringBuilderCustomizer {
  private static final Logger LOG = LoggerFactory.getLogger(TemplateBomDataWiring.class);

  private final TemplateBomService templateBomService;

  public TemplateBomDataWiring(TemplateBomService templateBomService) {
    this.templateBomService = templateBomService;
  }

  @Override
  public void customize(RuntimeWiring.Builder builder) {
    builder.scalar(Scalars.GraphQLBigDecimal);
    builder.scalar(GraphQLDate);
    builder.type("Query", typeWiring -> typeWiring.dataFetcher("templateBom", env -> {
      final String id = env.getArgument("id");
      return templateBomService.getTemplateBom(id);
    }));
    builder.type("Mutation", typeWiring -> typeWiring.dataFetcher("create", env -> {
      final String partMasterId = env.getArgument("partMasterId");
      return templateBomService.createTemplateBom(partMasterId);
    }));
    builder.type("Mutation", typeWiring -> typeWiring.dataFetcher("createLineItem", env -> {
      final String id = env.getArgument("id");
      final TemplateLineItemInput input = env.getArgument("input");
      return templateBomService.createTemplateLineItem(id, input);
    }));
  }

But I can't get the query to parse in GraphiQL. I get no stacktrace server side, I just get this in the GraphiQL UI...

{
  "errors": [
    {
      "message": "class java.util.LinkedHashMap cannot be cast to class com.example.boa.domain.TemplateLineItemInput (java.util.LinkedHashMap is in module java.base of loader 'bootstrap'; com.example.boa.domain.TemplateLineItemInput is in unnamed module of loader org.springframework.boot.devtools.restart.classloader.RestartClassLoader @617a9621)",
      "locations": [
        {
          "line": 42,
          "column": 3
        }
      ],
      "path": [
        "createLineItem"
      ],
      "extensions": {
        "classification": "INTERNAL_ERROR"
      }
    }
  ],
  "data": {
    "createLineItem": null
  }
}

I'm working pretty much off the https://www.graphql-java.com/documentation/v16/ docs

How do I get my input type to map into the TemplateLineItemInput POJO on graphql-java:16.2?

You can use spring boot to automatically define your runtime wiring. And you can write query fetchers or mutation fetchers by implementing

GraphQLQueryResolver
GraphQLMutationResolver

If you are doing the runtime wiring, the complex input parameters other than basic types will always be passed as key, value pairs in a LinkedHashmap. So you have to convert the passed linkedHashmap into the class you expect as below.

ObjectMapper objectMapper = new ObjectMapper();
            String input = objectMapper.writeValueAsString(env.getArgument("input"));
            final String arg = env.getArgument("input");
            return templateBomService.createTemplateLineItem(id, objectMapper.readValue(arg,TemplateLineItemInput.class));

QUESTION

Gradle api transitive dependencies not working

Asked 2021-May-25 at 09:11

I have a library project that I use to hold some setup for my other projects that has a lot of utility classed and also utility libraries included. So, I changed all my "implementation" calls in the library's build.gradle to "api" calls so I don't need to reimport the dependencies again and again. After building the library and moving the jar from my library folder to the lib folder inside my main project, I can access all the classes in my library, but the transitive dependencies are not available in my main project.

I also tried using implementation and transitive = true, but no luck.

I'm using AdoptOpenJDK 16 and Gradle 7.0 and I already tried to rebuild everything after cleaning the cache.

library's build.gradle

Information about transitive dependencies isn't included in Your jar. When You publish libraries to a repository via Maven or Gradle, there are several files being published:

obviously .jar file with all compiled code
pom.xml file (it contains transitive dependencies definitions)
some files with checksums

When You just copy Your library jar to lib directory, Your application has no information about it's dependencies. There are several solutions:

Publish Your library to Maven Repository (Sonatype Nexus or JFrog Artifactory are most popular products to set up self hosted repository, but You can also use mavenLocal()) instead of copying jar to lib - I think it's the best solution
Build library as fatJar (jar file with compiled code and all it's dependencies - Creating a Fat Jar in Gradle)
Copy all of Your library dependencies to lib folder
