Question

我正在研究Spring boot JPA Gridle project。当前Swagger正在运行，并且在DTO进行过程中发生错误。模块似乎相互冲突。

当我安装swagger模块，继续进行并为DTO安装模块时发生错误。以下模块会产生错误：

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

并且错误如下。

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

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

我在搜索中尝试过的内容也是如此。

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'

他们俩都没有帮助我。

有人和我有同样的问题吗？

还有其他解决方法吗？

Answer 1

问题是Swagger和Hateoas模块之间存在冲突。许多搜索结果找到了解决方案。

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));
    }

}
