报错的信息新版本的spring 跟swagger 不兼容引起的.

 解决办法1 配置文件中添加配置

spring:
#  swagger配置 必须加
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER

办法二

查看pom文件中是否添加依赖若是有的话把他排除掉

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
