spring GraphQL Java：带有springboot的GraphQL Java不加载游乐场http://localhost:3001/playground

Question

我有一个java spring boot graphql项目

我在^{中的依赖项：

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>com.graphql-java-kickstart</groupId>
            <artifactId>graphql-spring-boot-starter</artifactId>
            <version>12.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.graphql-java-kickstart</groupId>
            <artifactId>playground-spring-boot-starter</artifactId>
            <version>5.10.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

当我运行应用程序并访问http://localhost:3001/playground我收到一张空白的纸，上面写着

"Loading GraphQL Playground"

这可能是我的问题
