在@controller加入@RequestMapping，运行时后台无报错，但页面会显示404错误，看看是哪的问题，代码如下：
@Controller
@RequestMapping("/Cabinet")
public class CabinetListController{

@Autowired
private CabinetService cabinetService;

  @RequestMapping("/queryCabinet")
public ModelAndView queryCabinet() throws Exception {
// TODO Auto-generated method stub
List<CabinetHeadExtend> cabinetList =cabinetService.findCabinetHeadList(null);


ModelAndView modelAndView = new ModelAndView();

modelAndView.addObject("cabinetList",cabinetList );
modelAndView.setViewName("cabinet/cabinetList");
return modelAndView;
}

DEBUG时如下，访问controller正常，并且成功访问数据库，并且成功返回ModelAndView
