升级Spring Boot版本与Swagger2冲突的问题

在项目从spring boot1.x升级到2.2.6时，报错

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 3 were found:
	- relProviderPluginRegistry: defined by method 'relProviderPluginRegistry' in org.springframework.hateoas.config.HateoasConfiguration
	- linkDiscovererRegistry: defined in null
	- entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry' in class path resource [org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

请检查Swagger2 的依赖版本，

升级到2.9.2版本，并且替换自带的插件版本，否则还是会报上面的错误。

pom文件如下：

  <dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-swagger-ui</artifactId>
       <version>2.9.2</version>
  </dependency>
   <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.9.2</version>
   </dependency>
   <dependency>
         <groupId>org.springframework.plugin</groupId>
         <artifactId>spring-plugin-metadata</artifactId>
         <version>2.0.0.RELEASE</version>
     </dependency>
    <dependency>

          <artifactId>spring-plugin-core</artifactId>
