springMVC的RequestMapping请求不到路径的解决

@Controller 
public class UserController { 
 private UserService service = new UserServiceImpl();  
 @RequestMapping(value="/list",method=RequestMethod.GET)
 public String list(Model model) throws Exception {
  List<User> list = service.getAll(); 
  model.addAttribute("list", list); 
  return "list"; 
 } 
}
