上一篇说的是如何配置：https://blog.csdn.net/zhuwei_clark/article/details/104359187

但是在配置好之后启动总是报错，报错内容如下：

***************************
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:154)

The following method did not exist:

    org.springframework.plugin.core.PluginRegistry.getPluginOrDefaultFor(Ljava/lang/Object;Lorg/springframework/plugin/core/Plugin;)Lorg/springframework/plugin/core/Plugin;

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

    jar:file:/C:/work/maven/mymaven/repo/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:/C:/work/maven/mymaven/repo/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

其实标题就是问题的重点了，我们抓住重点进行查看，才发现引入的

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。

有目标就好解决，查了下maven仓库，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

第一步修改pom文件，去掉1.2.0：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${swagger.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.plugin</groupId>
                    <artifactId>spring-plugin-core</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework.plugin</groupId>
                    <artifactId>spring-plugin-metadata</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-spring-webflux</artifactId>
            <version>${swagger.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.plugin</groupId>
                    <artifactId>spring-plugin-core</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework.plugin</groupId>
                    <artifactId>spring-plugin-metadata</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>${swagger.version}</version>
        </dependency>

第二步引入：2.0.0

  <!-- 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，所以最后要放在前缀的POM文件里面，这样才能起效，也是往上大部分人说引入了没效果的原因。
