前言
上一章讲解了关于会议oa项目的排座功能，其中使用到了html2cavas插件,今天我们同样也会使用一款插件来完成我们的会议审批功能，当然，本片还会连同叫讲解送审以及会议反馈功能
功能演示
功能分析
送审功能
- 点击我的会议界面时，页面自动加载下拉框选项人员
- 当用户点击送审弹出送审界面，中间内嵌一个div包裹一个下拉框
- 点击确认送审时，用户向后端发送请求，携带参数会议id，以及送审人的id，用此传到后端来修改会议的状态以及审批人，然后刷新列表
审批功能
- 当用户点击我的审批，前端会自动往后端发送请求，将当前用户的id传达后端，如果当前用户的id是会议中的审批人id，那么就将这个会议查询出来
- 当用户点击审批功能时，获取到行数据，以及行id，弹出添加审核界面，子页面会继承父页面传过来的行参数，从而赋值，但是此时需要注意的是，如果需要赋值，那么此时子页面的name属性必须和传过来的行参数中的键名一样
if(parent.row!=null){ form.val('audit',$.extend({}, parent.row||{})); }
- 当用户点击审批通过时，因为子页面中的方法获取到了图像数据，但是审批通过按钮是基于父页面的，所以要从父页面调取子页面的方法
$(layero).find("iframe")[0].contentWindow.save();
- 我们将其封装成一个对象，然后再往这个对象中添加数据参数，一个是行id，一个是审批人的id，行id是打开审批界面的方法中传递过来的，此时审批人也就是登录的人是很早就保存在域对象中的，所以获取审批人的id也很容易，最后将封装好的对象，传递到后台进行逻辑处理
- 后面的图片下载的方法就和会议排座得方法一样了，看我的sql分析以及源码吧
会议通知功能
当用户登录打开会议通知时，用户会看到当前自己需要参加的还没有开始的会议，并且它的反馈信息是未读
会议反馈功能
当用户点击是否参会时，前端拿到数据往后台传送，在会议反馈表中新增一条会议反馈数据
反馈详情功能
当用户点击反馈详情时，浏览器从后端获取数据回显到前端，根据他们的反馈id分组
数据表分析
审批表，审批者点击审批通过的审批数据存放
反馈表，参会人员反馈时的信息存放处
会议表 会议管理的核心表
sql分析
送审sql
//修改会议审批人（会议送审） public int updateAuditorById(MeetingInfo info) throws Exception { String sql="update t_oa_meeting_info set auditor=?,state=2 where id=?"; return super.executeUpdate(sql, info, new String[] {"auditor","id"}); }
会议审批sql
public void add(MeetingAudit audit) { //1.新增会议审批记录 String sql="insert into t_oa_meeting_audit(meetingId,auditor,sign)" + " values("+audit.getMeetingId()+","+audit.getAuditor()+",'"+audit.getSign()+"')"; //2.根据会议ID更新会议的状态（3=驳回，4=待开） int state=StringUtils.isBlank(audit.getSign())?3:4; String sql1="update t_oa_meeting_info set state="+state+" where id="+audit.getMeetingId(); //如何一次执行两条SQL，使用数据库事务？ super.executeUpdateBatch(new String[] {sql,sql1}); }
这里一个方法用到了两条sql语句，解释起来有点麻烦，需要的兄弟在我的工具类中有basedao，直接去copy就OK了，
会议通知sql语句
public List<Map<String,Object>> queryMeetingFeedBackByUserId(MeetingFeedBack back,PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException{ String sql="select t1.*,ifnull(f.result,-1) result from \r\n" + "(select * from t_oa_meeting_info where " + "find_in_set('"+back.getPersonId()+"',concat(canyuze,',',liexize,',',zhuchiren))) t1 \r\n" + "left join t_oa_meeting_feedback f on " + "t1.id=f.meetingId and personId="+back.getPersonId()+" where f.result is null "; sql += " order by t1.id desc"; System.out.println(sql); return super.executeQuery(sql, pageBean); }
这段sql其实是比较复杂的了，需要熟悉两张表的结构才能够看得懂
现在将sql语句拆解来讲解
SELECT * FROM t_oa_meeting_info WHERE find_in_set('" + back.getPersonId() + "', concat(canyuze, ',', liexize, ',', zhuchiren)) and state =4
这段代码就是子查询部分，意思是查出当前登录的用户，在会议表中是参与者，列席者，主持者的所有待开会议，刚好满足我们的需求，因为我们的会议通知就是要做到，只看到自己需要参加的会议,
SELECT t1.*, IFNULL(f.result, -1) result FROM (子查询) t1 LEFT JOIN t_oa_meeting_feedback f ON t1.id = f.meetingId AND personId = '" + back.getPersonId() + "' WHERE f.result IS NULL
主查询部分其实就是在原有的基础上，还要根据另外一张反馈表，通过条件查询，只拿到我们还没有读的会议信息，因为这才叫做通知
反馈详情
1.1、先拿到所有参与人员的id
select concat (canyuzhe,',',liexizhe,',',zhuchiren)from t_oa_meeting_info where id=?
1.2、再拿到对应参与人员的姓名
select * from t_oa_user where find_in_set(id,(select concat (canyuzhe,',',liexizhe,',',zhuchiren)from t_oa_meeting_info where id=?))
2、连接反馈表，拿到对应的反馈情况
select t1.name,if(f.result,-1)result from (select * from t_oa_user where find_in_set(id,(select concat (canyuzhe,',',liexizhe,',',zhuchiren)from t_oa_meeting_info where id=?))) t1 left join t_oa_meeting_freeback f on t1.id = f.personid and f.meeting id=?
3、根据反馈情况进行分组
select t.result,group_concat(t.name)names form (select t1.name,if(f.result,-1)result from (select * from t_oa_user where find_in_set(id,(select concat (canyuzhe,',',liexizhe,',',zhuchiren)from t_oa_meeting_info where id=?))) t1 left join t_oa_meeting_freeback f on t1.id = f.personid and f.meeting id=?) t group by t.result
新增反馈
insert into t_oa_meeting_feedback values(?,?,?,?,?,?)

审批完成后就是会议通知和会议反馈了

反馈界面.jsp--用户点击是否参会的弹出的界面层
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@include file="/common/public.jsp"%> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript" src="${pageContext.request.contextPath }/static/js/meeting/addFeedBack.js"></script> </head> <style> body{ margin:5px; } </style> <body> <div style="padding:10px;"> <form class="layui-form layui-form-pane" lay-filter="back"> <!-- <div class="layui-form-item"> <button type="submit" class="layui-btn" lay-submit="" lay-filter="meeting">立即提交</button> <button id="reset" type="reset" class="layui-btn layui-btn-primary">重置</button> </div> --> <input type="hidden" name="meetingId" value="${param.id }"/> <input type="hidden" name="personId" value="${sessionScope.user.id }"/> <div class="layui-form-item"> <label class="layui-form-label">人员类型</label> <div class="layui-input-block"> <select id="personType" name="personType"> <option value="">请选择人员类型</option> <option value="1">参会</option> <option value="2">列席</option> </select> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">反馈结果</label> <div class="layui-input-block"> <select id="result" name="result"> <option value="">请选择反馈结果</option> <option value="1">参加</option> <option value="2">不参加</option> </select> </div> </div> <div class="layui-form-item layui-form-text"> <label class="layui-form-label">不参与会议的原因</label> <div class="layui-input-block"> <textarea placeholder="请输入内容" name="reason" class="layui-textarea"></textarea> </div> </div> </form> </div> </body> </html>
反馈界面js--内存在获取表单信息的方法
let form,$; layui.use(['form','jquery'],function(){ form=layui.form, $=layui.jquery; }); function getData(){ return form.val('back'); }
至此，所有的前端代码就展示到这里了，再理一遍流程吧
- 用户点击送审，弹出对话框，内嵌div，点击确认送审，直接更改会议数据
- 审批人登录之后，点击我的审批，查看到所有自己需要审批的会议，点击审批，弹出对话框，中间嵌套一个审批界面，一切签字操作都由审批界面js完成，但是审批通过是对话框中的，所以通过操作由我的审批界面js向后端发送请求，图像数据从子页面获取
- 审批通过之后，后台会增加一条审批数据，中间包含了审批人的id，审批会议id，还有签名信息，并且改变会议的审批人和状态信息
- 当用户登录进入系统，抓取到用户的id，到后端进行查询，如果这个用户是会议中的一员，就将这个会议查询出来，而且这个会议是待开状态中，而且这个人对这个会议的状态还是未读的
- 当用户点击是否参会时，弹出反馈界面，通过父亲调儿子的方法，获取子页面的值，然后添加进入反馈表中
- 最后当发布人进入我的会议时，点击反馈详情，然后弹出对话框，内嵌一个div，浏览器发送请求，根据会议的id，查询出整个会议的反馈情况，
