在 Spring Boot 中解析 graphql 模式时出错，如何解决？

Question

我有一个项目使用 Springboot 和 GraphQL。

我正在使用 Java11 和 Gradle 5.6.2。

在我的模块中，我为 GraphQl 添加了这些依赖项。

    // GraphQl
    implementation 'com.graphql-java-kickstart:graphql-spring-boot-starter:5.10.0'
    implementation 'com.graphql-java:graphiql-spring-boot-starter:5.0.2'
    implementation 'com.graphql-java-kickstart:voyager-spring-boot-starter:5.10.0'
    implementation 'com.graphql-java-kickstart:graphql-java-tools:5.6.1'

在我的src/main/java/no.domain.project 我有我的 SpringbootApplication。我还有一个名为 RootResolver 的文件夹，我在其中添加了以下类：

@Component
public class RootResolver implements GraphQLQueryResolver{

    public String getHello() {
        return "Hello World";
    }
}

我的schema.graphqls 有以下查询：

type Query {
    hello: String!
}

我可以使用 404 访问localhost:8080/grapiql。

但是当我运行项目时，我得到以下错误：

我缩短了错误消息。

是什么导致了这个问题。我看到它没有拾取我的架构，但为什么会这样？我看过很多教程都做了同样的事情，但我得到了这个错误。

有什么建议吗？

感谢您的帮助！

我想通了 :) 我需要添加一个gradle.properties 文件并添加kotlin.version=1.3.50，因为当您启动SpringApplication 时，您将收到错误NoClassDefFoundException，因为Spring Boot 覆盖了库正在使用的Kotlin 版本。
