目录
前言
上一篇讲述了本次项目的背景，开发的目的等。
编码工作完成了会议的发布功能，本次分享的内容为我的会议功能。
一、功能需求
我的会议：
登录后，当前账号是会议的主持人则，将该会议查询并展示。
数据查询通过主次人字段查询
由我的会议产品原型图可以得知，审批人使用的是姓名而不是编号，而会议状态应该是文字描述而不是状态的编号。
而且当我的会议中，会议没有审批人时，也要显示会议。存在我发布了会议，但还在考虑会议的合理、是否需要新增内容等，暂未选择审批人的情况。
数据库中startTime和endTime 是datetime类型，页面会显示一串数字，我们需要将其进行格式化。
结合以上情况
编写SQL语句进行数据查询，
SELECT a.id, a.title, a.content, a.canyuze, a.liexize, a.zhuchiren, b.NAME zhuchirenname, a.location, DATE_FORMAT( a.startTime, '%Y-%m-%d %H-%m-%s' ) startTime, DATE_FORMAT( a.endTime, '%Y-%m-%d %H-%m-%s' ) endTime, a.state, ( CASE a.state WHEN 0 THEN '取消会议' WHEN 1 THEN '新建' WHEN 2 THEN '待审核' WHEN 3 THEN '驳回' WHEN 4 THEN '待开' WHEN 5 THEN '进行中' WHEN 6 THEN '开启投票' WHEN 7 THEN '结束会议' ELSE '其他' END ) meetingstate, a.seatPic, a.remark, a.auditor, c.NAME auditorname FROM t_oa_meeting_info a INNER JOIN t_oa_user b ON a.zhuchiren = b.id LEFT JOIN t_oa_user c ON a.auditor = c.id
既然需求分析完，数据查询也差不多了，就开始我的会议功能的编码了。
二、编码（我的会议）
1、后台编码
MeetingInfoDao
package com.zking.dao;
import java.sql.SQLException;
import java.util.List;
import java.util.Map;
import com.zking.entity.MeetingInfo;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;
import com.zking.util.StringUtils;
public class MeetingInfoDao extends BaseDao<MeetingInfo>{
// 会议信息新增
public int add(MeetingInfo t) throws Exception {
String sql = "insert into t_oa_meeting_info"
+ "(title,content,canyuze,liexize,zhuchiren,location,startTime,endTime,remark) "
+ "values(?,?,?,?,?,?,?,?,?)";
return super.executeUpdate(sql, t, new String[] {"title","content","canyuze","liexize","zhuchiren","location","startTime","endTime","remark"});
}
//我的会议、其他菜单会用到。
private String getSQL() {
return "SELECT a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,b.`name`,a.location\r\n" +
",DATE_FORMAT(a.startTime,'%Y-%m-%d %H:%i:%s') as startTime\r\n" +
",DATE_FORMAT(a.endTime,'%Y-%m-%d %H:%i:%s') as endTime\r\n" +
",a.state\r\n" +
",(case a.state\r\n" +
"when 0 then '取消会议'\r\n" +
"when 1 then '新建'\r\n" +
"when 2 then '待审核'\r\n" +
"when 3 then '驳回'\r\n" +
"when 4 then '待开'\r\n" +
"when 5 then '进行中'\r\n" +
"when 6 then '开启投票'\r\n" +
"else '结束会' end\r\n" +
") as meetingState\r\n" +
",a.seatPic,a.remark,a.auditor,c.`name` as auditorName\r\n" +
"FROM t_oa_meeting_info a\r\n" +
"inner join t_oa_user b on a.zhuchiren = b.id\r\n" +
"left JOIN t_oa_user c on a.auditor = c.id where 1=1 ";
}
// 我的会议
public List<Map<String, Object>> myInfos(MeetingInfo info, PageBean pageBean) throws Exception {
String sql = getSQL();
String title = info.getTitle();
if(StringUtils.isNotBlank(title)) {
sql += " and title like '%"+title+"%'";
}
//根据当前登陆用户ID作为主持人字段的条件
sql+=" and zhuchiren="+info.getZhuchiren();
//按照会议ID降序排序
// sql+=" order by a.id desc";
System.out.println(sql);
return super.executeQuery(sql, pageBean);
}
// 取消会议
public int updateState(MeetingInfo info) throws Exception {
String sql = "update t_oa_meeting_info set state = 0 where id = ?";
return super.executeUpdate(sql, info,new String[] {"id"} );
}
}
MeetingInfoDaoTest
package com.zking.dao;
import static org.junit.Assert.*;
import java.sql.SQLException;
import java.util.List;
import java.util.Map;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import com.zking.entity.MeetingInfo;
import com.zking.util.PageBean;
public class MeetingInfoDaoTest {
private MeetingInfoDao infoDao = new MeetingInfoDao();
@Before
public void setUp() throws Exception {
}
@After
public void tearDown() throws Exception {
}
@Test
public void testMyInfos() {
MeetingInfo info = new MeetingInfo();
PageBean pageBean = new PageBean();
try {
List<Map<String, Object>> myInfos = infoDao.myInfos(info, pageBean);
for (Map<String, Object> map : myInfos) {
System.out.println(map);
}
System.out.println(pageBean);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
写好dao方法先测试一下，用junit。
MeetingInfoAction
package com.zking.web;
import java.util.Date;

import com.zking.util.MyDateConverter;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;
public class MeetingInfoAction extends ActionSupport implements ModelDriver<MeetingInfo>{
private MeetingInfo info = new MeetingInfo();
private MeetingInfoDao infoDao = new MeetingInfoDao();
@Override
public MeetingInfo getModel() {
// 注册一个转换器
ConvertUtils.register(new MyDateConverter(), Date.class);
return info;
}
public String add(HttpServletRequest req, HttpServletResponse resp) {
try {
// rs是sql语句执行的影响行数
int rs = infoDao.add(info);
if(rs > 0) {
ResponseUtil.writeJson(resp, R.ok(200, "会议信息数据新增成功"));
}else {
ResponseUtil.writeJson(resp, R.error(0, "会议信息数据新增失败"));
}
} catch (Exception e) {
e.printStackTrace();
try {
ResponseUtil.writeJson(resp, R.error(0, "会议信息数据新增失败"));
} catch (Exception e1) {
e1.printStackTrace();
}
}
return null;
}
// 我的会议
public String myInfos(HttpServletRequest req, HttpServletResponse resp) {
try {
PageBean pageBean = new PageBean();
pageBean.setRequest(req);
List<Map<String, Object>> list = infoDao.myInfos(info, pageBean);
// 注意：layui中的数据表格的格式
ResponseUtil.writeJson(resp, R.ok(0, "我的会议数据查询成功" , pageBean.getTotal(), list));
} catch (Exception e) {
e.printStackTrace();
try {
ResponseUtil.writeJson(resp, R.error(0, "我的会议数据查询失败"));
} catch (Exception e1) {
e1.printStackTrace();
}
}
return null;
}
// 取消会议
public String del(HttpServletRequest req, HttpServletResponse resp) {
try {
PageBean pageBean = new PageBean();
pageBean.setRequest(req);
int upd = infoDao.updateState(info);
// 注意：layui中的数据表格的格式
if(upd > 0) {
ResponseUtil.writeJson(resp, R.ok(200, "会议取消成功"));
}else {
ResponseUtil.writeJson(resp, R.error(0, "会议取消失败"));
}
} catch (Exception e) {
e.printStackTrace();
try {
ResponseUtil.writeJson(resp, R.error(0, "会议取消失败"));
} catch (Exception e1) {
e1.printStackTrace();
}
}
return null;
}
}
2、前端编码

let layer,table,$,form;
var row;
layui.use(['layer','table','jquery','form'],function(){
layer=layui.layer,
table=layui.table,
form=layui.form,

initTable();
//查询事件
$('#btn_search').click(function(){
query();
});
});
//1.初始化数据表格
function initTable(){
table.render({ //执行渲染
elem: '#tb', //指定原始表格元素选择器（推荐id选择器）
height: 400, //自定义高度
loading: false, //是否显示加载条（默认 true）
cols: [[ //设置表头
{field: 'id', title: '会议编号', width: 90},

{field: 'seatPic', title: '会议排座', width: 120,
templet: function(d){
if(d.seatPic==null || d.seatPic=="")
return "尚未排座";
else
return "<img width='120px' src='"+d.seatPic+"'/>";
}
},
{field: 'auditorName', title: '审批人', width: 120},
{field: '', title: '操作', width: 200,toolbar:'#tbar'},
]]
});
}
//2.点击查询
function query(){
table.reload('tb', {
url: 'info.action', //请求地址
method: 'POST', //请求方式，GET或者POST
loading: true, //是否显示加载条（默认 true）
page: true, //是否分页
where: { //设定异步数据接口的额外参数，任意设
'methodName':'myInfos',
'zhuchiren':$('#zhuchiren').val(),
'title':$('#title').val(),
},
request: { //自定义分页请求参数名
pageName: 'page', //页码的参数名称，默认：page
limitName: 'rows' //每页数据量的参数名，默认：limit
},
done: function (res, curr, count) {
console.log(res);
}
});
//工具条事件
table.on('tool(tb)', function(obj){ //注：tool 是工具条事件名，test 是 table 原始容器的属性 lay-filter="对应的值"
row = obj.data; //获得当前行数据
var layEvent = obj.event; //获得 lay-event 对应的值（也可以是表头的 event 参数对应的值）
var tr = obj.tr; //获得当前行 tr 的 DOM 对象（如果有的话）
console.log(row);
if(layEvent === 'seat'){ //会议排座
layer.msg('会议排座');
} else if(layEvent === 'send'){ //送审
layer.msg('送审');
} else if(layEvent==="back"){ //反馈详情
layer.msg('反馈详情');
} else {
layer.confirm('确认取消会议吗?', {icon: 3, title:'提示'}, function(index){
$.post('info.action',{
'methodName':'del',
'id':row.id
},function(rs){
if(rs.success){
//调用查询方法刷新数据
query();
}else{
layer.msg(rs.msg,function(){});
}
},'json');
layer.close(index);
});
}
});
}将会议排座，由文字变为图片
运行效果如下：
