用户列表管理

查询用户列表

业务逻辑

1. 判断page和pageSize是否合法
2. 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:

1. 判断穿越如用户id是否为空
2. 根据用户id查询用户对象
3. 修改用户对象中的状态码
4. 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();
    }
