記錄一下基于jeecg-boot3.0的待辦消息移植記錄

? ? 因為之前沒有記錄，所以還要看代碼進行尋找，比較費勁，所以今天記錄一下：

1、后端

SysAnnouncementController

下面函數增加待辦的幾個顯示內容給前端用

?具體代碼如下：

	/*** @功能：補充用戶數據，并返回系統消息* @return*/@RequestMapping(value = "/listByUser", method = RequestMethod.GET)public Result<Map<String, Object>> listByUser(@RequestParam(required = false, defaultValue = "5") Integer pageSize) {Result<Map<String,Object>> result = new Result<Map<String,Object>>();LoginUser sysUser = (LoginUser)SecurityUtils.getSubject().getPrincipal();String userId = sysUser.getId();// 1.將系統消息補充到用戶通告閱讀標記表中LambdaQueryWrapper<SysAnnouncement> querySaWrapper = new LambdaQueryWrapper<SysAnnouncement>();querySaWrapper.eq(SysAnnouncement::getMsgType,CommonConstant.MSG_TYPE_ALL); // 全部人員querySaWrapper.eq(SysAnnouncement::getDelFlag,CommonConstant.DEL_FLAG_0.toString());  // 未刪除querySaWrapper.eq(SysAnnouncement::getSendStatus, CommonConstant.HAS_SEND); //已發布querySaWrapper.ge(SysAnnouncement::getEndTime, sysUser.getCreateTime()); //新注冊用戶不看結束通知//update-begin--Author:liusq  Date:20210108 for：[JT-424] 【開源issue】bug處理--------------------querySaWrapper.notInSql(SysAnnouncement::getId,"select annt_id from sys_announcement_send where user_id='"+userId+"'");//update-begin--Author:liusq  Date:20210108  for： [JT-424] 【開源issue】bug處理--------------------List<SysAnnouncement> announcements = sysAnnouncementService.list(querySaWrapper);if(announcements.size()>0) {for(int i=0;i<announcements.size();i++) {//update-begin--Author:wangshuai  Date:20200803  for： 通知公告消息重復LOWCOD-759--------------------//因為websocket沒有判斷是否存在這個用戶，要是判斷會出現問題，故在此判斷邏輯LambdaQueryWrapper<SysAnnouncementSend> query = new LambdaQueryWrapper<>();query.eq(SysAnnouncementSend::getAnntId,announcements.get(i).getId());query.eq(SysAnnouncementSend::getUserId,userId);SysAnnouncementSend one = sysAnnouncementSendService.getOne(query);if(null==one){SysAnnouncementSend announcementSend = new SysAnnouncementSend();announcementSend.setAnntId(announcements.get(i).getId());announcementSend.setUserId(userId);announcementSend.setReadFlag(CommonConstant.NO_READ_FLAG);sysAnnouncementSendService.save(announcementSend);}//update-end--Author:wangshuai  Date:20200803  for： 通知公告消息重復LOWCOD-759------------}}// 2.查詢用戶未讀的系統消息Page<SysAnnouncement> anntMsgList = new Page<SysAnnouncement>(0, pageSize);anntMsgList = sysAnnouncementService.querySysCementPageByUserId(anntMsgList,userId,"1");//通知公告消息Page<SysAnnouncement> sysMsgList = new Page<SysAnnouncement>(0, pageSize);sysMsgList = sysAnnouncementService.querySysCementPageByUserId(sysMsgList,userId,"2");//系統消息Page<SysAnnouncement> todealMsgList = new Page<SysAnnouncement>(0, pageSize);todealMsgList = sysAnnouncementService.querySysCementPageByUserId(todealMsgList,userId,"3");//待辦消息Map<String,Object> sysMsgMap = new HashMap<String, Object>();sysMsgMap.put("sysMsgList", sysMsgList.getRecords());sysMsgMap.put("sysMsgTotal", sysMsgList.getTotal());sysMsgMap.put("anntMsgList", anntMsgList.getRecords());sysMsgMap.put("anntMsgTotal", anntMsgList.getTotal());sysMsgMap.put("todealMsgList", todealMsgList.getRecords());sysMsgMap.put("todealMsgTotal", todealMsgList.getTotal());result.setSuccess(true);result.setResult(sysMsgMap);return result;}

2、前端

HeaderNotice.vue 文件

獲取系統消息里增加待辦內容

同時顯示的地方做調整，包括樣式與內容顯示

消息通知彈出

?具體代碼如下：
