用户列表管理

查询用户列表

业务逻辑

判断page和pageSize是否合法
根据前端传入的参数进行查询

    @Override
    public GraceJSONResult queryAll(String nickname, Integer status, String startDate, String endDate, Integer page, Integer pageSize) {
        if (page == null) {
            page = 0;
        }

        if (pageSize == null) {
            pageSize = 10;
        }

        PageGridResult pageGridResult = appUserMngService.queryAllAppUserListByPage(nickname, status, startDate, endDate, page, pageSize);

        return GraceJSONResult.ok(pageGridResult);
    }

service业务逻辑

判断参数是否为空如果不为空直接拼接用户名模糊查询时间大于小于查询即可最后order by排序
然后分页查询将分页查询复制个result返回即可

  @Override
    public PageGridResult queryAllAppUserListByPage(String nickname, Integer status, String startDate, String endDate, Integer page, Integer pageSize) {


        QueryWrapper<AppUser> queryWrapper = new QueryWrapper<>();
        if (StringUtils.isNotBlank(nickname)) {
            queryWrapper.like("nickname", nickname);
        }

        if (status != null && status != 9) {
            queryWrapper.eq("active_status", status);
        }

        if (StringUtils.isNotBlank(startDate) && StringUtils.isNotBlank(endDate)) {
            queryWrapper.gt("created_time", startDate);
            queryWrapper.le("   created_time", endDate);
        }

        queryWrapper.orderByAsc("created_time");

        Page<AppUser> appUserPage = new Page<>(page, pageSize);

        Page<AppUser> appUserPageList = userMapper.selectPage(appUserPage, queryWrapper);

        PageGridResult pageGridResult = new PageGridResult();
        pageGridResult.setPage(appUserPageList.getCurrent());
        pageGridResult.setRows(appUserPageList.getRecords());
        pageGridResult.setTotal(appUserPageList.getTotal());
        pageGridResult.setRecords(appUserPageList.getTotal());

        return pageGridResult;
    }

用户详情

根据用户id查询用户并返回即可没什么好说的

    @Override
    public GraceJSONResult userDetail(String userId) {
        if (StringUtils.isBlank(userId)) {
            GraceException.display(ResponseStatusEnum.FAILED);
        }

        AppUser user = appUserService.getUser(userId);

        return GraceJSONResult.ok(user);
    }

   @Override
   public AppUser getUser(String userId) {
      return userMapper.selectById(userId);
   }

用户冻结/解冻

业务逻辑:

判断穿越如用户id是否为空
根据用户id查询用户对象
修改用户对象中的状态码
首先考虑用户在冻结和解冻之后肯定不能在进行之后的操作了所以要进行刷新一下将redis中保存的用户token删除用户进行操作时需要重新登录

    @Override
    public GraceJSONResult freezeUserOrNot(String userId, Integer doStatus) {
        if (StringUtils.isBlank(userId)) {
            GraceException.display(ResponseStatusEnum.FAILED);
        }

        if (doStatus == null) {
            GraceException.display(ResponseStatusEnum.FAILED);
        }

        AppUser user = appUserService.getUser(userId);
        if (user == null) {
            GraceException.display(ResponseStatusEnum.USER_NOT_EXIST_ERROR);
        }

        user.setActiveStatus(doStatus);

        appUserService.updateUser(user);

        // 修改状态后 清空session 当用户进行操作时 需要重新登录
        redisOperator.del(REDIS_USER_CACHE + ":" + userId);
        redisOperator.del(REDIS_USER_CACHE + ":" + userId);

        return GraceJSONResult.ok();
    }
