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
是浏览器的访问路径没填对
比如说这是你的controller 里面写的访问路径
@RequestMapping(value = {"/hello","/hi"} ,method = RequestMethod.GET)
这时访问localhost:8080/springboot/hi
就会报这个错，应该访问http://localhost:8080/hi
