因为之前没有记录，所以还要看代码进行寻找，比较费劲，所以今天记录一下：
1、后端
SysAnnouncementController
下面函数增加待办的几个显示内容给前端用
具体代码如下：
/**
* @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、前端
HeaderNotice.vue 文件
获取系统消息里增加待办内容
同时显示的地方做调整，包括样式与内容显示
消息通知弹出
具体代码如下：
<template>
<a-popover
trigger="click"
placement="bottomRight"
:autoAdjustOverflow="true"
:arrowPointAtCenter="true"
overlayClassName="header-notice-wrapper"
@visibleChange="handleHoverChange"
:overlayStyle="{ width: '400px', top: '50px' }">
<template slot="content">
<a-spin :spinning="loadding">
<a-tabs>
<a-tab-pane :tab="msg1Title" key="1">
<!--<a-list>
