嵌套返回result ,返回success

 public Result<Integer> readUnread(@RequestParam(name="employeeId",required=true) String employeeId) {
        Result<Integer> result = new Result<Integer>();
        int num = 0;
        QueryWrapper<SysAnnouncement> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("user_ids",employeeId);
        queryWrapper.eq("del_flag",AppInfoConstant.READ_0);
        queryWrapper.in("titile", "会议信息通知","家属信箱信息通知","请假审批提醒","加班调休审批提醒", "报警提醒");
        List<SysAnnouncement> sysAnnouncements = sysAnnouncementService.list(queryWrapper);
        for (SysAnnouncement sysAnnouncement : sysAnnouncements) {
            //删除通告阅读标记表
            QueryWrapper<SysAnnouncementSend> qs = new QueryWrapper<>();
            qs.eq("annt_id",sysAnnouncement.getId());
