这个部分是这个单元最后内容了，就是点击消息更多的一些代码与逻辑。
1、需要在我的个人中心里增加一个菜单我的消息
2、同时角色里进行授权给相应用户
3、增加后端代码
首先因为需要联合多表查询，所以需要进行一个新的数据结构如下：
/*** NoticeSendModel 用户通告阅读标记表** @author nbacheng* @date 2023-09-20*/
@Data
public class NoticeSendModel {/**id*/private java.lang.Long sendId;/**通告id*/private java.lang.Long noticeId;/**用户id*/private java.lang.Long userId;/**标题*/private java.lang.String noticeTitle;/**内容*/private java.lang.String noticeContent;/**发布人*/private java.lang.String sender;/**优先级（L低，M中，H高）*/private java.lang.String priority;/**阅读状态*/private java.lang.String readFlag;/**发布时间*/@JsonFormat(timezone = "GMT+8",pattern = "yyyy-MM-dd HH:mm:ss")@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")private java.util.Date sendTime;/**页数*/private java.lang.Integer pageNo;/**大小*/private java.lang.Integer pageSize;/*** 消息类型1:通知公告2:系统消息3:待办*/private java.lang.String noticeType;
}
同时mapper.xml文件需要增加下面sql联合查询
<resultMap id="NoticeSendModel" type="com.ruoyi.system.model.NoticeSendModel" ><result column="send_id" property="sendId" jdbcType="BIGINT"/><result column="notice_id" property="noticeId" jdbcType="BIGINT"/><result column="user_id" property="userId" jdbcType="BIGINT"/><result column="notice_title" property="noticeTitle" jdbcType="VARCHAR"/><result column="notice_content" property="noticeContent" jdbcType="VARCHAR"/><result column="sender" property="sender" jdbcType="VARCHAR"/><result column="priority" property="priority" jdbcType="VARCHAR"/><result column="notice_type" property="noticeType" jdbcType="VARCHAR"/><result column="send_time" property="sendTime" jdbcType="TIMESTAMP"/></resultMap><select id="getMyNoticeSendList" parameterType="Object" resultMap="NoticeSendModel">selectsns.send_id,sns.notice_id,sns.user_id,sns.read_flag,sa.notice_title as notice_title,sa.notice_content as notice_content,sa.sender as sender,sa.priority as priority,sa.notice_type as notice_type,sa.send_time as send_timefrom sys_notice_send snsleft join sys_notice sa ON sns.notice_id = sa.notice_idwhere sa.send_status = '1'and sa.status = '0'and sns.user_id = #{noticeSendModel.userId}<if test="noticeSendModel.noticeTitle !=null and noticeSendModel.noticeTitle != ''">and sa.notice_title LIKE concat(concat('%',#{noticeSendModel.noticeTitle}),'%')</if><if test="noticeSendModel.sender !=null and noticeSendModel.sender != ''">and sa.sender LIKE concat(concat('%',#{noticeSendModel.sender}),'%')</if><if test="noticeSendModel.readFlag !=null and noticeSendModel.readFlag != ''">and sns.read_flag = #{noticeSendModel.readFlag}</if><if test="noticeSendModel.noticeType !=null and noticeSendModel.noticeType != ''">and sa.notice_type = #{noticeSendModel.noticeType}</if>order by sns.read_flag,sa.send_time desc</select>
control接口层增加下面代码
/*** 获取我的消息* @return*/@SaCheckPermission("system:noticeSend:list")@PostMapping(value = "/getMyNoticeSend")public R<Page<NoticeSendModel>> getMyNoticeSend(@RequestBody JSONObject json) { LoginUser loginUser = commonService.getLoginUser();Long userId = loginUser.getUserId();Integer pageNum = json.getInteger("pageNum");Integer pageSize = json.getInteger("pageSize"); NoticeSendModel noticeSendModel = new NoticeSendModel();noticeSendModel.setUserId(userId);noticeSendModel.setPageNo((pageNum-1)*pageSize);noticeSendModel.setPageSize(pageSize);Page<NoticeSendModel> pageList = new Page<NoticeSendModel>(pageNum,pageSize);pageList = iSysNoticeSendService.getMyNoticeSendPage(pageList, noticeSendModel);return R.ok(pageList);}对应的实现就是调用mapper里sql
@Overridepublic Page<NoticeSendModel> getMyNoticeSendPage(Page<NoticeSendModel> pageList, NoticeSendModel noticeSendModel) {return pageList.setRecords(baseMapper.getMyNoticeSendList(pageList, noticeSendModel));}因为上面noticeSendModel是个sql参数，所以需要注意mapper接口层的写法如下，需要增加一个@Param("noticeSendModel")这样的参数：
/*** 用户公告阅读标记Mapper接口** @author nbacheng* @date 2023-09-21*/
public interface SysNoticeSendMapper extends BaseMapperPlus<SysNoticeSendMapper, SysNoticeSend, SysNoticeSendVo> {List<NoticeSendModel> getMyNoticeSendList(Page<NoticeSendModel> pageList, @Param("noticeSendModel")NoticeSendModel noticeSendModel);}
4、前端增加
我的消息页面
<template><div class="app-container"><el-form :model="queryParams" ref="queryForm" size="small" :inline="true" v-show="showSearch" label-width="68px"><el-form-item label="公告标题" prop="noticeTitle"><el-inputv-model="queryParams.noticeTitle"placeholder="请输入公告标题"clearable@keyup.enter.native="handleQuery"/></el-form-item><el-form-item label="操作人员" prop="createBy"><el-inputv-model="queryParams.createBy"placeholder="请输入操作人员"clearable@keyup.enter.native="handleQuery"/></el-form-item><el-form-item label="类型" prop="noticeType"><el-select v-model="queryParams.noticeType" placeholder="公告类型" clearable><el-optionv-for="dict in dict.type.sys_notice_type":key="dict.value":label="dict.label":value="dict.value"/></el-select></el-form-item><el-form-item><el-button type="primary" icon="el-icon-search" size="mini" @click="handleQuery">搜索</el-button><el-button icon="el-icon-refresh" size="mini" @click="resetQuery">重置</el-button></el-form-item></el-form><el-row :gutter="10" class="mb8"><el-col :span="1.5"><el-buttontype="success"plainicon="el-icon-edit"size="mini":disabled="single"@click=""v-hasPermi="['system:noticeSend:list']">全部标注已读</el-button></el-col><right-toolbar :showSearch.sync="showSearch" @queryTable="getList"></right-toolbar></el-row><el-table v-loading="loading" :data="noticeList" @selection-change="handleSelectionChange"><el-table-column type="selection" width="55" align="center" /><el-table-column label="序号" align="center" prop="noticeId" width="100" /><el-table-columnlabel="消息标题"align="center"prop="noticeTitle":show-overflow-tooltip="true"/><el-table-column label="消息类型" align="center" prop="noticeType" width="100"><template slot-scope="scope"><dict-tag :options="dict.type.sys_notice_type" :value="scope.row.noticeType"/></template></el-table-column><el-table-column label="发布人" align="center" prop="sender" width="100" /><el-table-column label="发布时间" align="center" prop="sendTime" width="100" /><el-table-column label="优先级" align="center" prop="priority" width="100"><template slot-scope="scope"><dict-tag :options="dict.type.sys_priority" :value="scope.row.priority"/></template></el-table-column><el-table-column label="阅读状态" align="center" prop="readFlag" width="100"><template slot-scope="scope"><dict-tag :options="dict.type.sys_readflag" :value="scope.row.readFlag"/></template></el-table-column><el-table-column label="操作" align="center" class-name="small-padding fixed-width"><template slot-scope="scope"><el-buttonsize="mini"type="text"icon="el-icon-view"@click="handleSee(scope.row)"v-hasPermi="['system:noticeSend:list']">查看</el-button></template></el-table-column></el-table><paginationv-show="total>0":total="total":page.sync="queryParams.pageNum":limit.sync="queryParams.pageSize"@pagination="getList"/><!-- 添加或修改公告对话框 --><el-dialog :title="title" :visible.sync="open" width="780px" append-to-body><el-form ref="form" :model="form" :rules="rules" label-width="80px"><el-row><el-col :span="12"><el-form-item label="公告标题" prop="noticeTitle"><el-input v-model="form.noticeTitle" placeholder="请输入公告标题" /></el-form-item></el-col><el-col :span="12"><el-form-item label="公告类型" prop="noticeType"><el-select v-model="form.noticeType" placeholder="请选择公告类型"><el-optionv-for="dict in dict.type.sys_notice_type":key="dict.value":label="dict.label":value="dict.value"></el-option></el-select></el-form-item></el-col><el-col :span="24"><el-form-item label="状态"><el-radio-group v-model="form.status"><el-radiov-for="dict in dict.type.sys_notice_status":key="dict.value":label="dict.value">{{dict.label}}</el-radio></el-radio-group></el-form-item></el-col><el-col :span="24"><el-form-item label="内容"><editor v-model="form.noticeContent" :min-height="192"/></el-form-item></el-col></el-row></el-form><div slot="footer" class="dialog-footer"><el-button type="primary" @click="">确 定</el-button><el-button @click="cancel">取 消</el-button></div></el-dialog></div>
</template><script>
import { listNotice, getMyNoticeSend, getNotice, updateNotice } from "@/api/system/notice";export default {name: "MyNotice",dicts: ['sys_readflag', 'sys_notice_type','sys_priority'],data() {return {// 遮罩层loading: true,// 选中数组ids: [],// 非单个禁用single: true,// 非多个禁用multiple: true,// 显示搜索条件showSearch: true,// 总条数total: 0,// 公告表格数据noticeList: [],// 弹出层标题title: "",// 是否显示弹出层open: false,// 查询参数queryParams: {noticeSendModel: {},pageNum: 1,pageSize: 10},// 表单参数form: {},// 表单校验rules: {noticeTitle: [{ required: true, message: "公告标题不能为空", trigger: "blur" }],noticeType: [{ required: true, message: "公告类型不能为空", trigger: "change" }]}};},created() {this.getList();},methods: {/** 查询公告列表 */getList() {this.loading = true;console.log("this.queryParams",this.queryParams);getMyNoticeSend(this.queryParams).then(res => {console.log("getMyNoticeSend res", res);this.noticeList = res.data.records;this.total = res.data.total;this.loading = false;});},// 取消按钮cancel() {this.open = false;this.reset();},// 表单重置reset() {this.form = {noticeId: undefined,noticeTitle: undefined,noticeType: undefined,noticeContent: undefined,status: "0"};this.resetForm("form");},handleSee(row) {},/** 搜索按钮操作 */handleQuery() {this.queryParams.pageNum = 1;this.getList();},/** 重置按钮操作 */resetQuery() {this.resetForm("queryForm");this.handleQuery();},// 多选框选中数据handleSelectionChange(selection) {this.ids = selection.map(item => item.noticeId)this.single = selection.length!=1this.multiple = !selection.length}}
};
</script>点击更多的跳转工作如下：
toMyNotice() {this.$router.push({path: '/personal/mynotice'});},
5、效果如下：
