目录
首先我们先来分析待开会议需要的SQL语句,分析得到的SQL代码如下:
- -- 待开会议与我的会议区别就是需要匹配三个数据库列段
- select CONCAT(
- canyuze,',',liexize,',',zhuchiren),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 '其它' 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 where 1=1
- and state = 4 and FIND_IN_SET(1,CONCAT(
- canyuze,',',liexize,',',zhuchiren))
然后我们分析所有会议的SQL语句和待开会议极为相似,就是多了一个审批者的数据库字段;所以我们就copy一份上面分析的来的SQL代码,修改一下就好啦。
就是要注意:要用IF NULL判断,不然就会因为有为空的审批人而丢失数据!
- -- 所有会议
- 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 '其它' 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 where 1=1
- and FIND_IN_SET(1,CONCAT(
- a.canyuze,',',a.liexize,',',a.zhuchiren,',',IFNULL(a.auditor,-1)))

3.2所有会议 meetingAll.js

- ]]
- });
- }
-
- //2.查询所有会议
- function query(){
- table.reload('tb_meeting', {
- 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

- limitName: 'rows' //每页数据量的参数名,默认:limit
- },
- done: function (res, curr, count) {
- //查询完成的回调函数
- }
- });
- }
我们编写Dao方法:
- //待开会议
- public List
- String sql = "select CONCAT(\r\n" +
- " canyuze,',',liexize,',',zhuchiren),a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,\r\n" +
- " b.`name` zhuchirenname,\r\n" +
- " a.location,\r\n" +
- " DATE_FORMAT(a.startTime,'%y-%m-%d %h-%M-%s') startTime,\r\n" +
- " DATE_FORMAT(a.endTime,'%y-%m-%d %h-%M-%s') endTime,\r\n" +
- " a.state,\r\n" +
- " (\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" +
- " when 7 then '结束会议'\r\n" +
- " else '其它' end \r\n" +
- " ) meetingstate,\r\n" +
- " a.seatPic,a.remark,a.auditor,\r\n" +
- " c.`name` auditorname 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\r\n" +
- " and state = 4 and FIND_IN_SET("+mi.getZhuchiren()+",CONCAT(\r\n" +
- " canyuze,',',liexize,',',zhuchiren))";
- return super.executeQuery(sql, pageBean);
- }
再就是Action层:
- //待开会议
- public String queryMeetingInfoByState(HttpServletRequest req, HttpServletResponse resp) {
- try {
- PageBean pageBean = new PageBean();
- //初始化
- pageBean.setRequest(req);
- List
- ResponseUtil.writeJson(resp, R.ok(0, "待开会议数据查询成功" ,pageBean.getTotal() ,list));
- } catch (Exception e) {
- e.printStackTrace();
- try {
- ResponseUtil.writeJson(resp, R.ok(0, "待开会议数据查询失败"));
- } catch (Exception e1) {
- e1.printStackTrace();
- }
- }
- return null;
- }
然后就是所有会议查询的后台代码了,这个和上面的待开会议的后台代码是一样步骤的:
依然是先写Dao方法:
- //所有会议
- public List
- String sql = "select a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,\r\n" +
- " b.`name` zhuchirenname,\r\n" +
- " a.location,\r\n" +
- " DATE_FORMAT(a.startTime,'%y-%m-%d %h-%M-%s') startTime,\r\n" +
- " DATE_FORMAT(a.endTime,'%y-%m-%d %h-%M-%s') endTime,\r\n" +
- " a.state,\r\n" +
- " (\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" +
- " when 7 then '结束会议'\r\n" +
- " else '其它' end \r\n" +
- " ) meetingstate,\r\n" +
- " a.seatPic,a.remark,a.auditor,\r\n" +
- " c.`name` auditorname 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\r\n" +
- " and FIND_IN_SET("+mi.getZhuchiren()+",CONCAT(\r\n" +
- " a.canyuze,',',a.liexize,',',a.zhuchiren,',',IFNULL(a.auditor,-1)))";
- return super.executeQuery(sql, pageBean);
- }
然后就是Action层:
- //所有会议
- public String allInfos(HttpServletRequest req, HttpServletResponse resp) {
- try {
- PageBean pageBean = new PageBean();
- //初始化
- pageBean.setRequest(req);
- List
- ResponseUtil.writeJson(resp, R.ok(0, "所有会议数据查询成功" ,pageBean.getTotal() ,list));
- } catch (Exception e) {
- e.printStackTrace();
- try {
- ResponseUtil.writeJson(resp, R.ok(0, "所有会议数据查询失败"));
- } catch (Exception e1) {
- e1.printStackTrace();
- }
- }
- return null;
- }
5.1 测试
上面的代码全部编写好了后,我们就可以来测试一下了!
待开会议:

所有会议:

所有会议也全部都查询出来啦~
OK,以上就是Leaf今天带来的关于会议OA项目的几个功能代码分享,喜欢的可以关注一起学习噢,有不理解的地方也可以私信来问我一起学习噢,我们下次见!!!
