public class UserManageController {
 
    @Autowired
    private UserService userService;
 
    
    @RequestMapping("/list")
    public String findUserListByPage(UserVo vo){
        LayuiTableDataResult userListByPage = userService.findUserListByPage(vo);
        return JSON.toJSONString(userListByPage);
    }
 
    
    @RequestMapping("/add")
    public String addUser(UserVo vo){
        Map<String, Object> map = userService.addUser(vo);
        return JSON.toJSONString(map);
