spring boot ---Whitelabel Error Page

想试一下spring boot的hello world，可是出错了

错误：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

No message available

 

 

404？？访问资源没找到。怎么可能呢

 

经过网上搜索终于找到原因了，controller必须在spring boot的启动程序的包或子包

 

 新建一个包com.exammple.demo.controller

将IndexController.java移到com.example.demo.controller下

然后访问http://localhost:8080/

 

 ok啦
