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">
	   select
	   		sns.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_time
	   from sys_notice_send sns
	   left join sys_notice sa ON sns.notice_id = sa.notice_id
	   where 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

@Override
	public 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>
      <el-form-item label="操作人员" prop="createBy">

<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!=1
      this.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：
