03.OA项目之我的会议（查询&会议排座&送审）
目录
会议查询
会议排座
会议送审
思路：
- 关键性会议SQL的编写
- 后台实现
- 前台实现
会议查询
MeetingInfoDao.java
// 通用的会议查询SQL语句，包含会议信息表数据，主持人姓名、审批人姓名、会议状态
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> 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);
} MeetingInfoAction.java
// 我的会议
public String myInfos(HttpServletRequest req, HttpServletResponse resp) {
try {
PageBean pageBean = new PageBean();
pageBean.setRequest(req);
List> infos = meetingInfoDao.myInfos(info, pageBean);
ResponseUtil.writeJson(resp, R.ok(0, "我的会议查询成功！！！", pageBean.getTotal(), infos));
} catch (Exception e) {
e.printStackTrace();
try {
ResponseUtil.writeJson(resp, R.error(0, "我的会议查询失败！！！"));
} catch (Exception e1) {
e1.printStackTrace();
}
}
return null;

myMeeting.js
会议排座
思路
- 会议排座插件介绍
- 会议排座功能开发
- 送审功能开发
MeetingInfoDao.java
// 根据会议ID更新会议的排座图片
public int updateSeatPicById(MeetingInfo info) throws Exception {
String sql="update t_oa_meeting_info set seatPic=? where id=?";
return super.executeUpdate(sql, info, new String[] {"seatPic","id"});
}
// 根据会议ID查询相关用户
public List queryUserByMeetingId(Long meetingId) throws Exception{
String sql="select * from t_oa_user where FIND_IN_SET(id,"
+ "(select concat(canyuze,',',liexize,',',zhuchiren) "
+ "from t_oa_meeting_info where id="+meetingId+"))";
return super.executeQuery(sql, User.class, null);
} MeetingInfoAction.java
/**
* 保存排座图片到服务器的指定目录，并更新相关会议信息的排座图片字段
* @param req
* @param resp
*/
public void addArrangeSeat(HttpServletRequest req, HttpServletResponse resp) {
try {
String fName = UUID.randomUUID().toString().replace("-", "").concat(".jpg");
String path = "D:\\temp\\images\\seatPic\\uploads\\" + fName;
String base64Image = meetinginfo.getSeatPic().replace("data:image/png;base64,", "");
//生成图片
Base64ImageUtils.GenerateImage(base64Image, path);
//更新会议信息表中的排座信息，需要设置tomcat的设置增加一个扩展web模块
meetinginfo.setSeatPic("/uploads/"+fName);
service.updateSeatPicById(meetinginfo);
CommonUtil.sendResponse(0, "排座成功", resp);
} catch (Exception e) {
e.printStackTrace();
CommonUtil.sendResponse(-1, "排座失败", resp);
}
}resource.properties
String path = "D:\\temp\\images\\seatPic\\uploads\\" + fName;在tomcat中需要配置图片映射关系
myMeeting.js
seatPic.jsp
注：添加jQuery、html2canvas相关插件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
会议座位安排
会议送审
MeetingInfoDao.java
// 根据会议ID更新会议的审批人（送审）
@Override
public void updateMeetingState(Meetinginfo meetingInfo) {
String sql = "update t_oa_meeting_info set state = ? where id = ?";
DbTemplate.update(sql, new Object[] {meetingInfo.getState(), meetingInfo.getId()});
}MeetingInfoAction.java
/**
* 会议送审，能够送审的前提是该会议已经排座，否则不能送审，此外
* 对于审核通过，结束，取消，进行中等状态的会议不能执行送审
* @param rep
* @param resp
*/
public void sendAudit(HttpServletRequest rep, HttpServletResponse resp) {
try {
service.sendAudit(meetinginfo);
CommonUtil.sendResponse(0, "送审成功", resp);
} catch (Exception e) {
e.printStackTrace();
CommonUtil.sendResponse(-1, "送审失败", resp);
}
}myMeeting.js
