为什么启动类要加注解@EnableWebMvc

SpringBoot启动类为什么要添加@EnableWebMvc？

See docs.spring.io/spring/docs/current/spring-framework-reference/…. Does it work, yes, is it sufficient it might. But the version you use still has the old DefaultAnnotationHandlerMapping instead of the newer more powerful/flexible RequestMappingHandlerMapping and other classes. – M. Deinum Sep 16 '16 at 13:42

知道大概为啥了，但是并不知道这个RequestMappingHandlerMapping这个有什么高级的特性

具体这个注解是干嘛的？看这个（需要梯子），https://stackoverflow.com/questions/19291329/enablewebmvc-annotation-meaning，这里有官方文档的连接
