使用示例

@RestController
@RequestMapping("admin/user")
public class AdminUserController extends BaseController{

    @Autowired
    private UserService userService;

    @GetMapping("/userView")
    public ModelAndView userView() {
        ModelAndView modelAndView = new ModelAndView("user/user");
        return modelAndView;
    }

    @GetMapping("/addUserView")
    public ModelAndView addUserView() {
        ModelAndView modelAndView = new ModelAndView("user/userAdd");
        return modelAndView;
    }

    @GetMapping("/updateUserView")
    public ModelAndView updateUserView(@RequestParam Long id) {
        ModelAndView modelAndView = new ModelAndView("/admin/userUpdate");
        modelAndView.addObject("user", userService.getUserDetail(id));
        return modelAndView;
    }
}
