            Unable to generate interface with openapi-generator-gradle-plugin
            Asked 2021-Dec-19 at 14:14

            I'm trying to generate models and controller interfaces with openapi-generator-gradle-plugin.

            The problem I'm having is that the plugin in generating classes instead of interfaces.

            A generated class looks like this:



            Answered 2021-Dec-19 at 14:14

            The java generator (simply) doesn't support (gracefully(? -> debug/verbose!)) the interfaceOnly option.

            Try generatorName = "spring" or refer to one of the generators documented in the parent directory.

            SpringBoot2 Configuration JOOQ MariaDB: "required a bean of type 'javax.sql.DataSource' that could not be found"
            Asked 2021-Sep-13 at 13:20

            it's not the first time this question was asked and i read a lot of article about this topic, but I can't solve this problem:

            Field dataSource in de.foo.MariaDbConfig required a bean of type 'javax.sql.DataSource' that could not be found.

            All my configurations are like in this articles. Code generation worked properly with a given ddl sql file. The database is a MariaDB. Why does this error keep appearing?

            So Simon Martinelli helped me by finding the solution inside stackoverflow. After removing the hole config class, i got this "DSLContext that could not be found" error. Then i found this question:

            How to fix "Consider defining a bean of type 'org.jooq.DSLContext' in your configuration." after update to jOOQ 3.15.0

            Which solved my problem completly. Sorry for asking a question that has already been solved, but nothing pointed into the direction of R2dbcAutoConfiguration.

            So, as Simon already said, removing the config class and, as the answer in this question already pointed out, adding @SpringBootApplication(exclude = { R2dbcAutoConfiguration.class }) solved the problem.

            Request validation doesn't happen in camel rest
            Asked 2021-May-23 at 20:33

            I am trying to experiment by building some simple API's with apache camel. The request body for a post request is empty but camel doesn't return bad request instead it returns 201.

            Here is what I do;

            1. Generate classes from studentreg-api.yaml [This is a valid openapi 3 yaml document]
            2. Using camel, spring boot to build REST endpoints Step
            3. Configured camel rest endpoint with clientRequestValidation(true)
            4. Start the server
            5. Open /api-docs and validated if the mandatory attributes are marked appropriately
            6. From postman made request to the POST endpoint with blank request body

            Expected: 400 - Bad request Actual: 201

            I couldn't figure out what is that I am missing.




            Answered 2021-May-23 at 20:33

            ok! I have figured out a simpler way to handle validation. Adding a route to bean-validator solved the problem! If we need to build custom error messages or if you need to build error model based on failures, you can use camel processor and javax.validator.

            Migrating from Tomcat to Undertow org.springframework.web.servlet lib issues
            Asked 2021-May-03 at 15:08

            I've searched Stack and google looking for an answer to no luck. So I'm hoping someone can help me here.

            I have a Spring Boot API which is currently using Tomcat, now I've read about some of the performance improvements in Undertow so I wanted to give it a go and see for myself.

            Now, I've removed my spring-boot-web-starter dependancy and added undertow however I'm getting the following errors in a few classes and I can't seem to find how to resolve them:



            Answered 2021-May-03 at 15:08

            By excluding spring-boot-starter-web you did exclude all its dependencies, which are necessary to run a Spring Boot project in a servlet environment. Most notably you did exclude spring-web, which contains most of the classes you find in the error messages.

            As its name suggests spring-boot-starter-web isn't centered around Tomcat, only its dependency spring-boot-starter-tomcat is. So you should exclude the latter artifact and include spring-boot-starter-undertow to pull the necessary Undertow dependencies into the project:

            OpenAPI Maven Plugin for Java Generating Inconsistent Classes
            Asked 2021-Apr-21 at 21:59

            We are using the openapi-generator-maven-plugin version 5.0.1 to generate our APIs. I am trying to specify a request that includes a DTO and also a file.

            The first weird thing is that the generated code doesn't use the DTO, it basically flattens the fields, so that the API expects each of the fields to be specified. However, we're not really too concerned about this issue, because we can just specify each field (although it would be nice if it worked as expected).

            The problem that is killing us is that the generated classes for the API and the API Delegate are not consistent with each other. The generated API treats each of the fields as a String. However, the API Delegate treats them as Optional. So when we try to compile the code, the API gets a compile error because it's passing String to the Delegate, and the Delegate wants Optional.

            Here is our POM, with the related dependencies and plugin config:



            Answered 2021-Apr-21 at 21:59

            Using allOf combines all schema listed in one. The properties of EmailRequestDTO and those of the inline defined object are generated as parameters and not as a DTO. See https://swagger.io/docs/specification/data-models/oneof-anyof-allof-not/#allof

            If you don't want Optional String are generated as parameter in the delegate, remove useOptional configuration. See https://openapi-generator.tech/docs/generators/spring/

            Disable JSR-303 annotation processing in springdoc
            Asked 2021-Apr-01 at 10:13

            How can I disable JSR-303 annotation processing in springdoc for specific fields?

            I have the following request class MyRequestTO where the field name is actually optional. The @NotBlank annotation is only applied to the unwrapped JsonNullable. This means the user is allowed to omit the field when sending MyRequestTO but if set it must not be blank. However the open api doc marks the name field as required. Changing the @Schema annotation to @Schema(type = "string", required = false) does not help.

            I want to avoid a solution where I have to write my own annotation and make use of org.springdoc.core.customizers.OpenApiCustomiser. The desired solution should also work for other types like JsonNullable annotated with @NotNull.



            Answered 2021-Mar-26 at 10:03

            This is not working as @NotBlank allow null values

            The @NotNull class isValid() method is called after the @NotBlank class isValid(), hence forbidding null values.

            So you can try with @Pattern with validation of not black string as follows :

            Openapi codegen by gradle plugin: UI not showing correctly
            Asked 2021-Feb-19 at 09:11

            I'm trying to test openapi codegenerator via gradle plugin. So, I have .yml file with documentation (ran it in https://editor.swagger.io/ , looks cool)



            Answered 2021-Feb-19 at 09:11

            The ui you see is not generated from the documentation .yml file you use to generate your code. Instead, the ui is generated from the generated code, which has it's own annotations that currently are springfox annotations, which are swagger2 annotations instead of openapi 3 annotations (although your original file is openapi 3).

            Generated openapi 3 annotations support is coming soon, but in any case, in short, you should have to complete missing annotations and necessary beans yourself, but this way makes it very hard to match the resulting openapi definition to your original documentation file.

            Luckily there's a better alternative: Just add your yml file in src/main/resources/static and add this line to your application.properties file:

            When I build my war via my gradle build file, can I include the classes autogenerated from Avro schema?

            Look at the war file when its exploded it doesnt seem to include those classes.

            I'm having an issue with getting my Kafka / confluent spring boot with gradle project up and running. I originally had just a producer in this test project and everything was running well. I then added a Kafka consumer and now I get an exception on start up. Would anyone be able to spot the problem here:

            Firstly this is the stacktrace



            Answered 2021-Jan-22 at 20:37

            Boot 2.3 uses spring-kafka 2.5 by default (and kafka-clients 2.5.0); since you have overridden its prescribed spring-kafka version to 2.6.5, you must override all of the kafka dependencies to match

            kafka-clients 2.6.1, kafka-streams 2.6.1 (if you are using them).

            If you are using the embedded Kafka broker in tests, there are a bunch of other jars you need. See https://docs.spring.io/spring-kafka/docs/current/reference/html/#update-deps

            2.6.x is used by Boot 2.4 and will bring in all the right versions.

            Confluent 5.4 uses Kafka 2.4.

            You should use the version of confluent that matches Spring Boot's prescribed versions of spring-kafka, kafka-clients.

            If you use Boot 2.4.x, use confluent 6.0.
