我正在使用Spring Cloud将一个模块化应用程序迁移到一个微服务应用程序中，当我完成将一个模块迁移到微服务并运行它时，出现了一个问题：

更正应用程序的类路径，使其包含单一兼容版本的org.springframework.plugin.core.PluginRegistry
这是错误：

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.of(Ljava/util/List;)Lorg/springframework/plugin/core/PluginRegistry;

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

    jar:file:/~/.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:/~/.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

将此依赖项添加到您的依赖项部分解决了问题：

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

对我来说，我使用的是spring fox版本2.9.2，在springFox版本做了一些更改后，我发现解决这个问题的最佳方法是使用 springfox-starter 版本，它为你做了所有的事情。

<dependency>
 <groupId>io.springfox</groupId>
 <artifactId>springfox-boot-starter</artifactId>
</dependency>

为什么你缺少Sping Boot starter插件。它负责所有匹配的依赖版本。如果它由Spring管理，请不要显式指定任何jar版本。有一个Spring- Boot -dependency jar浏览它以查找Spring管理的版本。您也可以参考Spring文档页面https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#dependency-versions-coordinates。

与SprintBoot 2.3.3.只有这解决了我：

这是我在使用Spring-boot 2.3.4-RELEASE版本配置SWAGGER 2.9.2时遇到的相同问题。如果我将SWAGGER版本指向3.0.0，我会遇到白色标签错误的问题。最后，我修复了这个问题并记录了配置SWAGGER 3.0.0的步骤
当多个版本的SPRING-CORE-PLUGIN作为依赖项下载的一部分被下载时，将发生此问题。

以前我的pom.xml文件父是

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.2.0</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

字符串
当我改变我的pom.xml文件父版本3.2.0降级到2.7.17。然后应用程序的工作。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.17</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

型
当降级时，我们需要更换这些包

import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.Table;

型
成

import javax.persistence.*;

型
在完成这些事情后，我的应用程序开始正常工作

swagger 更正应用程序的类路径，使其包含一个兼容的org.springframework.plugin.core.PluginRegistry版本
