我正在使用 Spring Cloud 将模块化应用程序迁移到微服务应用程序中，当我完成将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，使其包含单个兼容版本的 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
这是我的pom.xml：

有人可以帮助我吗，因为我尝试了很多方法但没有任何效果。
将此依赖项添加到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>
</dependency>
对我来说，我使用了 Spring Fox 版本 2.9.2，在对 springFox 版本进行一些更改后，我遇到了同样的问题，我发现解决问题的最佳方法是使用 springfox-starter 版本，它可以完成所有操作给你的事。问题的原因是版本冲突。
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
</dependency>
为什么缺少 Spring boot starter 插件。它负责所有匹配的依赖版本。如果由 Spring 管理，则不要显式指定任何 jar 版本。有一个 Spring-boot-dependency jar，浏览它可以找到 Spring 管理的版本。您还可以参考Spring文档页面https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#dependency-versions-coordinates。
使用 SprintBoot 2.3.3。只有这个解决了我的问题：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-releasetrain</artifactId>
<version>Neumann-SR4</version>
<scope>import</scope>
<type>pom</type>
</dependency>
这与我在使用 Spring-boot 2.3.4-RELEASE 版本配置 SWAGGER 2.9.2 时遇到的问题相同。如果我将 SWAGGER 版本指向 3.0.0，我会遇到白标错误的问题。最后，我解决了问题并记录了配置步骤SWAGGER 3.0.0
作为依赖项下载的一部分下载多个版本的 SPRING-CORE-PLUGIN 时，会出现此问题。
以前我的 pom.xml 文件父级是
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.2.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
当我更改 pom.xml 文件时，父版本 3.2.0 降级到 2.7.17。然后应用程序工作。
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.17</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
降级时我们需要更换这些包
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.Table;
进入
import javax.persistence.*;
完成这些事情后，我的应用程序开始正常工作
