【问题描述】：

我正在处理Spring boot JPA Gridle project。当前Swagger 正在运行，而DTO 正在进行时发生错误。模块似乎相互碰撞。

当我安装 swagger 模块时发生错误，继续大摇大摆，并为 DTO 安装模块。以下模块产生错误：

compile 'org.springframework.boot:spring-boot-starter-hateoas'

而且报错如下。

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

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

    springfox.documentation.spring.web.plugins.DocumentationPluginsManager.createContextBuilder(DocumentationPluginsManager.java:152)

The following method did not exist:

    org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;Lorg/springframework/plugin/core/Plugin;)Lorg/springframework/plugin/core/Plugin;

The method's class, org.springframework.plugin.core.PluginRegistry, is available from the following locations:

    jar:file:/Users/****/.gradle/caches/modules-2/files-2.1/org.springframework.plugin/spring-plugin-core/2.0.0.RELEASE/95fc8c13037630f4aba9c51141f535becec00fe6/spring-plugin-core-2.0.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

It was loaded from the following location:

    file:/Users/****/.gradle/caches/modules-2/files-2.1/org.springframework.plugin/spring-plugin-core/2.0.0.RELEASE/95fc8c13037630f4aba9c51141f535becec00fe6/spring-plugin-core-2.0.0.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.plugin.core.PluginRegistry


Process finished with exit code 1

我通过搜索尝试的东西也是如此。

compile group: 'org.springframework.plugin', name: 'spring-plugin-core', version: '2.0.0.RELEASE'

compile group: 'io.springfox', name: 'springfox-data-rest', version: '2.9.2'

他们都没有帮助我。

有没有人和我一样的问题？

有没有其他方法可以解决这个问题？

【解决方案1】：

问题是 Swagger 和 Hateoas 模块之间的冲突。多条搜索结果都找到了解决办法。

解决方案是添加一个新模块并为其注册Bean。

compile group: 'org.springframework.plugin', name: 'spring-plugin-core', version: '1.2.0.RELEASE'

SwaggerConfig.java

public class SwaggerConfig {

    @Bean
    public LinkDiscoverers discoverers() {
        List<LinkDiscoverer> plugins = new ArrayList<>();
        plugins.add(new CollectionJsonLinkDiscoverer());
        return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
    }

}

【解决方案2】：

对我来说，问题在于 JPA 和 Hateoas 依赖项之间的冲突。

我的解决方案是删除 JPA 依赖项，因为我有兴趣改用 Hateoas 模块。

改变了这个：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
    </dependency>

到这里：

    <dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
    </dependency>
