解决Correct the classpath of your application so that it contains compatible versions

• springboot启动失败
• 报错Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.web.servlet.handler.AbstractHandlerMethodMapping and org.springframework.web.method.HandlerMethod

排查发现：pom依赖同时引用了两个不同版本的web包。

删掉一个web依赖重新构建以后问题直接解决。
