}

public class UserServerImp extends ServiceImpl<UserRepository, User> implement UserServer{ @Autowired
    private UserRepository userMapper;
   public JSONObject listUser(com.alibaba.fastjson.JSONObject params) {
        //返回值
        com.alibaba.fastjson.JSONObject outcome = new com.alibaba.fastjson.JSONObject();
        //转换实体
        User item = JSON.toJavaObject(params, User.class);
        
        //处理信息并设置返回分页信息
        IPage<User> userPage = this.UserMapper.selectUserPage(
                new Page(params.getLongValue(FIELD_CURRENT),
                        params.getLongValue(FIELD_SIZE)), item);
        
        outcome.put("user", userPage);
        return outcome;
  }
