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 ）：

 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 ）

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)

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 

package com.zking.entity;

import java.io.Serializable;
/**
 * t_oa_meeting_feedback   Meeting feedback form 
 *  Entity class ： Meeting feedback 
 * @author  President Yang

 */
public class MeetingFeedBack implements Serializable {

	private String id;
	private Long meetingId;
	private Integer personType;
	private Long personId;
	private Integer result;
	private String reason;

	//  The title of the meeting 
	private String title;

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public Long getMeetingId() {
		return meetingId;
	}

	public void setMeetingId(Long meetingId) {
		this.meetingId = meetingId;
	}

	public Integer getPersonType() {
		return personType;
	}

	public void setPersonType(Integer personType) {
		this.personType = personType;

	}

	public void setPersonId(Long personId) {
		this.personId = personId;
	}

	public Integer getResult() {
		return result;
	}

	public void setResult(Integer result) {
		this.result = result;
	}

	public String getReason() {
		return reason;
	}

	public void setReason(String reason) {
		this.reason = reason;
	}

	public MeetingFeedBack() {
		super();
		// TODO Auto-generated constructor stub
	}

	@Override
	public String toString() {
		return "MeetingFeedBack [id=" + id + ", meetingId=" + meetingId + ", personType=" + personType + ", personId="
				+ personId + ", result=" + result + ", reason=" + reason + "]";
	}

}

MeetingFeedBackDao：

package com.zking.dao;

import java.sql.SQLException;
import java.util.List;
import java.util.Map;

import com.zking.entity.MeetingFeedBack;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;

public class MeetingFeedBackDao extends BaseDao<MeetingFeedBack>{

	// Meeting notice query 
	public List<Map<String, Object>> queryMeetingFeedBackByUserId(MeetingFeedBack back, PageBean pageBean)
			throws SQLException, InstantiationException, IllegalAccessException {
		String sql="SELECT\r\n" + 
				"	IFNULL(f.result,-1) result,t1.*\r\n" + 
				" FROM\r\n" + 
				" (SELECT * from t_oa_meeting_info where FIND_IN_SET("+back.getPersonId()+",CONCAT(canyuze,',',liexize,',',zhuchiren)) and state=4) t1\r\n" + 
				" LEFT JOIN t_oa_meeting_feedback f on t1.id=f.meetingId\r\n" + 
				" and f.personId="+back.getPersonId()+"\r\n" + 
				" ORDER BY result";
		
	return super.executeQuery(sql, pageBean);
	}
//	back.getPersonId()
}

MeetingFeedBackAction：

package com.zking.web;

import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.zking.dao.MeetingFeedBackDao;
import com.zking.entity.MeetingFeedBack;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;

public class MeetingFeedBackAction extends ActionSupport implements ModelDriver<MeetingFeedBack>{
	private MeetingFeedBack back=new MeetingFeedBack();
	private MeetingFeedBackDao backDao=new MeetingFeedBackDao();
	@Override
	public MeetingFeedBack getModel() {
		return back;
	}

//	 Meeting notice query 
	public String queryMeetingFeedBackByUserId(HttpServletRequest req, HttpServletResponse resp) {
		try {
			PageBean pageBean=new PageBean();
			pageBean.setRequest(req);
			List<Map<String, Object>> infos = backDao.queryMeetingFeedBackByUserId(back, pageBean);
//		 Be careful ：layui Format of data table in 
			ResponseUtil.writeJson(resp, R.ok(0, " Meeting notification data query succeeded ",pageBean.getTotal(),infos));
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.error(0, " Meeting notification data query failed "));
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
		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 {
		String sql="select \r\n" + 
				" t.result,GROUP_CONCAT(t.name) names\r\n" + 
				" from\r\n" + 
				" (select \r\n" + 
				" t1.name,IFNULL(f.result,-1) result\r\n" + 
				" from\r\n" + 
				" (SELECT * from t_oa_user where FIND_IN_SET(id,	(SELECT CONCAT(canyuze,',',liexize,',',zhuchiren) from\r\n" + 
				"	t_oa_meeting_info \r\n" + 
				"	where id="+back.getMeetingId()+"))) t1\r\n" + 
				" left join t_oa_meeting_feedback f on t1.id=f.personId and f.meetingId="+back.getMeetingId()+") t\r\n" + 
				" GROUP BY t.result";
				return super.executeQuery(sql, pageBean);
	}

MeetingFeedBackAction：

// Meeting feedback details 
	public String queryMeetingBackByMeetingId(HttpServletRequest req, HttpServletResponse resp) {
		try {
			PageBean pageBean=new PageBean();
			pageBean.setRequest(req);
			List<Map<String, Object>> lst = backDao.queryMeetingBackByMeetingId(back, pageBean);
//		 Be careful ：layui Format of data table in 
			ResponseUtil.writeJson(resp, R.ok(0, " Meeting feedback details data query succeeded ",pageBean.getTotal(),lst));
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.error(0, " Meeting feedback details data query failed "));
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
		return null;
	}

Running effect ：

For example, log in here （ Zhang Qiang ） account number , Yes   The first 8 strip   Give feedback ： 

  It shows that Zhang Qiang is absent .
