无法重定向到控制器，总是获得404

时间：2018-01-27 16:24:34

标签： java spring spring-mvc spring-java-config

我正在使用javaconfig来设置这个项目，但我不知道我做错了什么。我打开localhost:8080，显示"hello world "，但是当我打开localhost:8080/home或localhost:8080/blog/home时，显示404未找到。调试器没有相关信息。

  1. ide：idea 2017
  2. 服务器：tomcat 9
  3. os：mac 10.13
  4. no web.xml only java config

    5. 项目结构： structure
