使用这些依赖项，我收到以下错误：

    *************************** 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:/home/md7zn4/.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

    It was loaded from the following location:

        file:/home/md7zn4/.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

如果我删除 Hal Browser Dependency 一切正常：

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-rest-hal-browser</artifactId>
            <version>3.2.5.RELEASE</version>
        </dependency>

我试图更新spring-plugin-core到，2.0.0-RELEASE但这次我收到以下错误：

***************************
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.Plugin org.springframework.plugin.core.PluginRegistry.getPluginFor(java.lang.Object, org.springframework.plugin.core.Plugin)'

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

    jar:file:/home/md7zn4/.m2/repository/org/springframework/plugin/spring-plugin-core/2.0.0.RELEASE/spring-plugin-core-2.0.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

我也检查这个。

我认为spring-plugin-core 如何解决这个问题存在冲突？

Answer 1

原因

显示此错误时：

The following method did not exist:

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

这意味着 spring-plugin-core 1.2.0 已生效。这对 springfox-swagger2 v2.9.2 很好，但是，其他一些组件在 spring-plugin-core 中找不到 PluginRegistry.of(java.util.List)，因为它是在更高版本中定义的。

显示此错误时：

The following method did not exist:

'org.springframework.plugin.core.Plugin org.springframework.plugin.core.PluginRegistry.getPluginFor(java.lang.Object, org.springframework.plugin.core.Plugin)'

这意味着 spring-plugin-core 2.0.0 已生效。这一次，springfox-swagger2 v2.9.2遇到了问题，因为PluginRegistry.getPluginFor(java.lang.Object, org.springframework.plugin.core.Plugin)从这个版本中被删除了。

解决方案

您可以使用 springfox 库的快照版本来解决此问题。它已升级为使用较新版本的 spring-plugin-core。

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>3.0.0-SNAPSHOT</version>
</dependency>

请添加存储库定义以使用此快照版本：

<repositories>
  <repository>
    <id>jcenter-snapshots</id>
    <name>jcenter</name>
    <url>http://oss.jfrog.org/artifactory/oss-snapshot-local/</url>
  </repository>
</repositories>

还请用@EnableSwagger2WebMvc 替换@EnableSwagger2。

Answer 2

就我而言，我只是升级了我的 swagger 版本，并且它起作用了。

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>3.0.0</version>
</dependency>

Answer 3

Spring Plugins 版本低，将这个添加到 pom.xml 中。

<dependency>
        <groupId>org.springframework.plugin</groupId>
        <artifactId>spring-plugin-core</artifactId>
        <version>2.0.0.RELEASE</version>
 </dependency>
