以前に記録がないため、コードを見て見つけるのは難しいため、今日記録します。
1. バックエンド
Sysアナウンスコントローラー
以下の関数はフロントエンドに行うべきいくつかの表示内容を追加します。
具体的なコードは次のとおりです。
/**
* @功能：补充用户数据，并返回系统消息
* @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.将系统消息补充到用户通告阅读标记表中
LambdaQueryWrapper<SysAnnouncement> querySaWrapper = new LambdaQueryWrapper<SysAnnouncement>();
querySaWrapper.eq(SysAnnouncement::getMsgType,CommonConstant.MSG_TYPE_ALL); // 全部人员
querySaWrapper.eq(SysAnnouncement::getDelFlag,CommonConstant.DEL_FLAG_0.toString()); // 未删除
querySaWrapper.eq(SysAnnouncement::getSendStatus, CommonConstant.HAS_SEND); //已发布
querySaWrapper.ge(SysAnnouncement::getEndTime, sysUser.getCreateTime()); //新注册用户不看结束通知
//update-begin--Author:liusq Date:20210108 for：[JT-424] 【开源issue】bug处理--------------------
querySaWrapper.notInSql(SysAnnouncement::getId,"select annt_id from sys_announcement_send where user_id='"+userId+"'");
//update-begin--Author:liusq Date:20210108 for： [JT-424] 【开源issue】bug处理--------------------
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： 通知公告消息重复LOWCOD-759--------------------
//因为websocket没有判断是否存在这个用户，要是判断会出现问题，故在此判断逻辑
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： 通知公告消息重复LOWCOD-759------------
}
}
// 2.查询用户未读的系统消息
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");//系统消息
Page<SysAnnouncement> todealMsgList = new Page<SysAnnouncement>(0, pageSize);
todealMsgList = sysAnnouncementService.querySysCementPageByUserId(todealMsgList,userId,"3");//待办消息
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. フロントエンド
Header Notice.vue ファイル
取得システム メッセージに ToDo コンテンツを追加する
同時に、スタイルやコンテンツの表示など、表示される場所を調整します
メッセージ通知ポップアップ
具体的なコードは次のとおりです。
