1. 报错背景介绍

笔者由于黑鸭子扫描结果需要，对本组的项目进行springboot版本进行升级，由于之前项目所用版本较低，为1.5.3，需要升级到2.2.x，结果出现如下错误：

 1 Description:

20 Action:
21 
22 Correct the classpath of your application so that it contains a single, compatible version of org.springframework.plugin.core.PluginRegistry

2. 解决方案：

从报错信息

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

可知，spring-plugin-core是1.2.0版本，但是在这个版本里面是没有上述方法。通过查看maven仓库-https://mvnrepository.com/，发现这个jar包就几个版本，不是在低版本就是在高版本中。查验之后发现这个方法是在2.0.0版本中存在的。所以目标明确，去掉1.2.0，引入2.0.0版本，maven依赖如下：

1）修改原pom文件，去掉swagger中引入的1.2.0版本

 1 <dependency>
 2             <groupId>io.springfox</groupId>
 3             <artifactId>springfox-swagger2</artifactId>
 4             <version>2.9.2</version>
 5             <exclusions>
 6                 <exclusion>
 7                     <groupId>org.springframework.plugin</groupId>
 8                     <artifactId>spring-plugin-core</artifactId>
 9                 </exclusion>
10                 <exclusion>
11                     <groupId>org.springframework.plugin</groupId>
12                     <artifactId>spring-plugin-metadata</artifactId>
13                 </exclusion>
14             </exclusions>
15         </dependency>
16         <dependency>
17             <groupId>io.springfox</groupId>
18             <artifactId>springfox-swagger-ui</artifactId>
19             <version>2.9.2</version>

2）新引入spring-plugin-core的2.0.0版本

<!-- https://mvnrepository.com/artifact/org.springframework.plugin/spring-plugin-core -->
        <dependency>
            <groupId>org.springframework.plugin</groupId>
            <artifactId>spring-plugin-core</artifactId>
            <version>2.0.0.RELEASE</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.springframework.plugin/spring-plugin-metadata -->
        <dependency>
            <groupId>org.springframework.plugin</groupId>
            <artifactId>spring-plugin-metadata</artifactId>
            <version>2.0.0.RELEASE</version>
        </dependency>

但是注意一点，这个jar需要提前引入，所以最好要放在父POM文件里面，这样才能起效，否则可能会没效果。
