Springboot 3 and GraphQL compatibility

I am upgrading my spring boot application from 2.1.6.RELEASE to 3.0.0 After resolving all the errors, the graphql apis are returning null and even the breakpoints are not getting triggered in any of the classes.

Does Spring boot 3 have support for GraphQL?

The following post kind of indicates that the support is not available but need some confirmation. https://spring.io/blog/2022/11/22/spring-for-graphql-1-0-3-released

Solution 
  • Upgrade to Spring Boot 3 and Java 17

Migrated to spring boot version 3.0.0 from 2.1.6.RELEASE
Migrated to Java 17 from Java 8
Removed GraphQLQueryResolver and GraphQLMutationResolver -  as they were not working
Used the following instead:
    Added @QueryMapping and @MutationMapping
    Changed Query and Mutation classes from @Component to @Controller
    Added jakarta.persistence-api dependency
    @Argument keyword added to the parameters in functions

Used the following dependency
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-graphql</artifactId>
        </dependency>
