Exception with GraphiQlHandler

[mehhras]

Hi All,

I recently faced a problem with GraphiQlHandler, but It used to be OK until yesterday. The problem is that when I want to run my project I see this exception:

***************************
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:

    org.springframework.graphql.boot.GraphQlWebMvcAutoConfiguration.graphQlRouterFunction(GraphQlWebMvcAutoConfiguration.java:120)

The following method did not exist:

    'void org.springframework.graphql.web.webmvc.GraphiQlHandler.<init>(java.lang.String)'

The method's class, org.springframework.graphql.web.webmvc.GraphiQlHandler, is available from the following locations:

    jar:file:/C:/Users/mehhr/.gradle/caches/modules-2/files-2.1/org.springframework.graphql/spring-graphql/1.0.0-SNAPSHOT/7c920987c7c8e6c9c00dc95c411dad7d12c69336/spring-graphql-1.0.0-SNAPSHOT.jar!/org/springframework/graphql/web/webmvc/GraphiQlHandler.class

The class hierarchy was loaded from the following locations:

    org.springframework.graphql.web.webmvc.GraphiQlHandler: file:/C:/Users/mehhr/.gradle/caches/modules-2/files-2.1/org.springframework.graphql/spring-graphql/1.0.0-SNAPSHOT/7c920987c7c8e6c9c00dc95c411dad7d12c69336/spring-graphql-1.0.0-SNAPSHOT.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.graphql.web.webmvc.GraphiQlHandler

Thank you in advance.

Are you still using the experimental starter? This starter is now defunct and you should use the official Spring Boot starter from now on: https://docs.spring.io/spring-boot/docs/2.7.0-SNAPSHOT/reference/html/web.html#web.graphql

[mehhras]

Thank you for your response. I changed it to what this link says.

But my project cannot find RuntimeWiringConfigurer. Is this file in another library?

[mehhras]

And when I commented the line, my builder says:

Could not find org.springframework.boot:spring-boot-starter-graphql:. Should I add another configuration?

[bclozel]

Do you have a sample application we can take a look at? It's probably a build configuration issue.

[mehhras]

Sure. It's my build.gradle

[bclozel]

You'll need Spring Boot 2.7.0-SNAPSHOT for that. This is why the starter cannot be found in your project.
