更正应用程序的类路径，使其包含org.springframework.plugin.core.PluginRegistry的一个兼容版本

我浏览了很多链接，比如-，但我还是发现了下面的错误-

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:

    org.springframework.data.rest.core.support.UnwrappingRepositoryInvokerFactory.<init>(UnwrappingRepositoryInvokerFactory.java:57)

The following method did not exist:

    'org.springframework.plugin.core.PluginRegistry org.springframework.plugin.core.PluginRegistry.of(java.util.List)'

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

    jar:file:/C:/Users/pc/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

The class hierarchy was loaded from the following locations:

    org.springframework.plugin.core.PluginRegistry: file:/C:/Users/pc/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar


Action:

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

源代码在这里-

让我们看看您的依赖关系树（

mvn-dependency:tree

）：

看来

springfox-swagger2

正在引入

spring插件元数据：jar:1.2.0.RELEASE

。该依赖关系需要

spring-plugin-core:jar:1.2.0.RELEASE

，该版本被跳过，因为您明确请求使用不同的版本

您需要：

• 在

  springfox-swagger2

  依赖项声明中排除

  spring插件元数据

  ，添加对

  spring插件元数据：2.0.0.RELEASE

  的显式依赖项，并希望

  spring插件元数据：2.0.0.RELEASE

  和

  spring插件元数据：1.2.0.RELEASE

  具有兼容的API（他们可能不会）
• 将

  spring-plugin-core

  的依赖版本更改为

  1.2.0.RELEASE
