JAVA framework SpringMVC RequestMapping explanation

1. Narrow the request mapping

Do RequestMapping annotation on the class.

Benefits: Avoid duplication of urls with other people in the same project, resulting in request confusion, and easy management.

1 @Controller
2 @RequestMapping(value = "/goods")
3 public class goodsController {
4     @Resource(name="goodsServiceImpl")
5     private goodsService goodsService;
