One 、 Meeting notice query SQL

Two 、 Meeting feedback details SQL

3、 ... and 、 Meeting notification background code implementation

Four 、 Meeting feedback function is realized

5、 ... and 、 The feedback details function is realized

One 、 Meeting notice query SQL（ difficulty ）

Sign in xx account number , Find out what xx It's the participants 、 Sit here as nonvoting delegates 、 One of the hosts , Then find out

Query criteria ： The logged in user id 2

analysis （ Tables involved ）：

Meeting information sheet ：t_oa_meeting_info

Meeting feedback form ：t_oa_meeting_feedback

example ： 1、 Query and bring xx id=2 Meeting information for ：
SELECT * from t_oa_meeting_info where FIND_IN_SET(2,CONCAT(canyuze,',',liexize,',',zhuchiren))
 and state=4
function SQL result ：

2、 Whether the meeting gets feedback or not , You have to find out , So choose External connection , The meeting information table is mainly ：
SELECT
    IFNULL(f.result,-1) result,t1.*
FROM
(SELECT * from t_oa_meeting_info where FIND_IN_SET(2,CONCAT(canyuze,',',liexize,',',zhuchiren)) and state=4) t1
LEFT JOIN t_oa_meeting_feedback f on t1.id=f.meetingId
and f.personId=2
 ORDER BY result;
function SQL result ：

Two 、 Meeting feedback details SQL（ difficulty ）

analysis （ Tables involved ）：

User table ：t_oa_user

Meeting information sheet ：t_oa_meeting_info

Meeting feedback form ：t_oa_meeting_feedback

Query criteria ： meeting id 12

1、 Get the meeting id by 12 Conference , Names of all participants

1） Get all the participants first id
SELECT CONCAT(canyuze,',',liexize,',',zhuchiren) from
	t_oa_meeting_info where id=12
SQL Running results ：

2) Then get the names of the corresponding participants
SELECT * from t_oa_user 
where 
FIND_IN_SET(id,	(SELECT  CONCAT(canyuze,',',liexize,',',zhuchiren)
from
t_oa_meeting_info where id=12))
SQL Running results ：

2、 Connect Meeting information feedback form , Get the corresponding feedback （ unread 、 To participate in 、 Do not participate ）

SELECT * from t_oa_user where FIND_IN_SET(id,	(SELECT CONCAT(canyuze,',',liexize,',',zhuchiren) from
	t_oa_meeting_info where id=12))

SQL Running results ：

3、 according to Group the meeting information feedback

select 
t.result,GROUP_CONCAT(t.name) names
from
(select 
t1.name,IFNULL(f.result,-1) result
from
(SELECT * from t_oa_user where FIND_IN_SET(id,	(SELECT CONCAT(canyuze,',',liexize,',',zhuchiren) from
	t_oa_meeting_info 
	where id=12))) t1
left join t_oa_meeting_feedback f on t1.id=f.personId and f.meetingId=12) t
GROUP BY t.result

SQL Running results ：

3、 ... and 、 Meeting notification background code implementation

Here is a brief mention of The front-end code ：

header.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<link rel="stylesheet" href="${pageContext.request.contextPath }/static/js/layui/css/layui.css">
<!--  introduce  layui.js -->
<script src="${pageContext.request.contextPath }/static/js/layui/layui.js"></script>
<!--  Specify the root path of the entire project  -->
<base href="${pageContext.request.contextPath }/"/>
<!--  Deposit layui Configuration file of extension module  -->
<script src="${pageContext.request.contextPath }/static/js/layui/config.js"></script>

<input id="ctx" value="${pageContext.request.contextPath }" type="hidden"/>
<title> Yuyuan studio </title>

front SQL Statements have been written , And then Start implementing background code 了：

Entity class ：MeetingFeedBack Corresponding meeting feedback form

}

MeetingFeedBackDao：

package com.zking.dao;

import java.sql.SQLException;

	return super.executeQuery(sql, pageBean);
	}
//	back.getPersonId()
}

MeetingFeedBackAction：

package com.zking.web;

		return null;
	}
	
}

mvc.xml:

<action path="/feedBack" type="com.zking.web.MeetingFeedBackAction">
	</action>

The operation effect is as follows ：

Four 、 Meeting feedback function is realized （ Whether to attend the meeting ）

MeetingFeedBackDao：

//	 Meeting feedback 
	public int add(MeetingFeedBack back) throws Exception {
		String sql="insert into t_oa_meeting_feedback values (?,?,?,?,?,?)";
		// The front desk didn't deliver id Go backstage , So generate it yourself id
		back.setId(UUID.randomUUID().toString().replace("-", ""));
		return super.executeUpdate(sql, back, new String [] {"id","meetingId","personType","personId","result","reason"});
	}

MeetingFeedBackAction：

// Meeting feedback 
	public String add(HttpServletRequest req, HttpServletResponse resp) {
		try {
//			rs yes sql Number of lines affected by statement execution 
			int rs = backDao.add(back);
			if(rs>0) {
				ResponseUtil.writeJson(resp, R.ok(200, " The feedback from the meeting was successful "));
			}else {
				ResponseUtil.writeJson(resp, R.error(0, " Meeting feedback failed "));
			}
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.error(0, " Meeting feedback failed "));
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
		return null;
	}

Next run ：

Click the meeting feedback button ：

We'll find that No 16 There is no more data , Enter the database to query Meeting information feedback form （t_oa_meeting_feedback）：

The conference feedback function has been realized ~

5、 ... and 、 The feedback details function is realized

MeetingFeedBackDao：

//	 Meeting feedback details 
	public List<Map<String, Object>> queryMeetingBackByMeetingId(MeetingFeedBack back, PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException {
