QUESTION
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.
...ANSWER
Answered 2022-Mar-24 at 08:19I 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:
QUESTION
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:

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
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:

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

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

QUESTION
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:
...ANSWER
Answered 2021-Oct-05 at 15:36Find 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
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
...ANSWER
Answered 2021-Sep-16 at 12:40The 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 WebSocketServletContainerInitializer for the implementation you are using. (where is one of Javax, Jakarta, or Jetty)
Since it looks like you are using javax.websocket, here's the appropriate class to use.
QUESTION
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!

Answered 2021-Sep-05 at 17:48In graphql-java implementation by default, all the resolver is called sequentially.

QUESTION
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.

Answered 2021-May-25 at 09:11Information 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 tolib- I think it's the best solutionBuild 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

Install graphql-java
You can use graphql-java like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the graphql-java component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
