一、会议排座插件介绍
需求背景：
1.实现思路:
2.明确开发会议座位的意义
1.查询会议中的所有参与者。2.需要完成页面上元素的拖动功能，并将相应的参与者放在指定的位置，如：重要人员放在主位置3。保存已绘制的会议座位图，并绑定到会议数据中；
1.查找资料
2.分析现有材料的不足
3.修改现有材料的不足
4.分析现有材料，如何与业务需求相关联(最重要的一步)
5.content只有这样，我们才能通过代码来确定图片存储在哪里
六、开始写我们的会议座位
二、会议参与用户数据初始化
三、生成和展示会议排座图片
1.保存已绘制的会议座位图，并绑定到会议数据上；
四、会议送审
1.会议排座插件介绍
我们没有会议桌。考虑到简单性，我们删除了它。但是项目桌将用于公司的一些项目
需求背景：
集团公司的日常管理会议和人事任命会议
1.实现思路:
①、查找资料
做选择，哪一个素材更适合完成需求
②、素材改造
材料缺陷：
1)样式:座椅小方块重叠/太小
2)截图区域大小
3)滚动条截图的问题需要解决
思考：
a、找到js连接到当前素材的功能p
b、查看素材源码，分析作者是依靠屏幕大小截屏还是html元素定位截屏（优先考虑）
③、代码预演
④、前后台代码整合
⑤、功能微调及实现
⑥、变种需求的完成
2.明确了开发会议排座的意义
思考如何去完成这个功能？
2.页面上元素的拖动功能（特殊的功能） 出发点：可以自己写、网上会有素材 流程：先找网上素材，改动素材中的源码，变为自己想要的 1.找网上素材，多找几个，挑出一个最适合的 2.分析现有素材的不足 ①、发现元素重叠，无法判定有几个人参会 ②、元素块太小看不清 3.修改现有素材的不足 4.分析现有素材，怎么与业务需求进行关联（最重要的一步） 其实需要做的是，查看源代码，分析图片生成的原因/步骤 下载 按钮是绑定了一个方法，这个主要的方法是downloadFile方法 downloadFile方法有两个参数：FileName、content，接下就是思考哪个参数与图片有关系 结论：通过分析downloadFile方法中content参数就代表了那张图片-前端
5.content需要传递到后台，并且生成图片，只有这样，我们才能通过代码决定图片存放在哪里 ①、怎么传后台-$.post $.get(不行的，因为参数太大) 错 ②、String content 字符串要转换成图片
1.查找资料
1.找网上素材，多找几个，挑出一个最适合的
可以去网上搜索如图所示：
点进去里有div还有HTML代码还有css还有js方法，通过这种方法找到几种案例如图所示：
第一种：
第二种：
第二种可以拖动但它是移到下面去了如图所示：这种就不符合
但第一种的可以：它添加的座位就会被覆盖，不太友好，但可以拖动，所以说我们从网上拿到的素材不一定符合，所以我们要改把改把。
2.分析现有素材的不足
①、发现元素重叠，无法判定有几个人参会 ②、元素块太小看不清
3.修改现有素材的不足
这个方块的样式取决于谁如图所示：
我们就来改变它的展示形式如图所示：
最终素材改造如图所示：
我们可以下载一下如图所示：就贴近了我们最上面的那张图了，就是没有桌子
4.分析现有素材，怎么与业务需求进行关联（最重要的一步）
但我们下载的时候它是指定位置，而不能我想下载哪里就下载哪里
其实需要做的是，查看源代码，分析图片生成的原因/步骤
下载 按钮是绑定了一个方法，这个主要的方法是downloadFile方法 downloadFile方法有两个参数：FileName、content，接下就是思考哪个参数与图片有关系 结论：通过分析downloadFile方法中content参数就代表了那张图片-前端
5.content需要传递到后台，并且生成图片，只有这样，我们才能通过代码决定图片存放在哪里

我们数据库里有一个Base64ImageUtils.java代码块,
我们最终要改的效果如图所示：
运行一下：
六、开始写我们的会议排座
当我们点击会议排座的时候是不是要弹出一个页面出来所以我们就新建一个jsp

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',
'title':$('#title').val(),
'zhuchiren':$('#zhuchiren').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
}
});
}
//打开会议排座对话框
function open(id){
layer.open({
type: 2, //layer提供了5种层类型。可传入的值有：0（信息框，默认）1（页面层）2（iframe层）3（加载层）4（tips层）
title: '会议排座', //对话框标题
area: ['460px', '340px'], //宽高
skin: 'layui-layer-rim', //样式类名
content: $("#ctx").val()+'/jsp/meeting/seatPic.jsp?id='+id, //弹出内容。可以传入普通的html内容，还可以指定DOM，更可以随着type的不同而不同
});
}运行结果就出来了：
我们现在希望我查询了那些人就绑定上去，现在我们这个是手动添加上去的吧
二、会议参与用户数据初始化
1.将 会议排座3.html 转变成jsp页面，本质上就是将某一条会议数据的所有参与人员查询出来 点击会议排座应该要默认初始化参会人员
-- 会议排座用户查询
select * from t_oa_meeting_info where id=6
-- 最终希望查询出这样的结果
select * from t_oa_user where id in (1,2,3,4,5)
-- 这行代码就等价于上面的 1,2,3,4,5
select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id=6
-- 实际结果
select * from t_oa_user where id in ('1,2,3,4,5')
select * from t_oa_user where id in (select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id=6)
-- FIND_IN_SET
-- 第一个参数：数据库列段
-- 第二个参数：是列段的条件
select * from t_oa_user where FIND_IN_SET(id,(select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id=6))
最终想要的结果如图所示：
我们就要去UserAction里面写这个方法:

UserDao.java代码块：
package com.zking.dao;
import java.sql.SQLException;

return users==null || users.size()==0?null:users.get(0);
// return super.executeQuery(sql, clz, pageBean);

// 查询用户信息及对应的角色，角色是通过case when得来的
public List<Map<String, Object>> list(User user,PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException{

}
我们在运行一下如图所示：
导入资料中的三个文件进入工程
第一个就是seatPic.jsp代码块我们copy了
第二个就是 html12canvas.js
第三个就是 jqury-3.3.1.min.js
我所放在的位置如图所示：
我们赋值过去就要对应好位置放入这张图就是我们F12检查出来的如图所示：
现在我们在来测试一下如图所示：
三、会议排座图片生成及展示
当我们点击下载的时候图片的字符串要传递到后台去，而这个字符串的字节很长如图所示：
$.get(不行的，因为参数太大）
①、怎么传后台-$.post
所以说我们要用post提交，当我们点击下载的时候是不是触发了这个事件如图所示：
通过这个方法调用里面的这个方法帮我把这个图片保存到后台的某一个磁盘里面去
保存在哪里面就是这个里面：
dirPath=E:/temp/images/T280/ serverPath=/test_layui/upload/paizuo/ dirPathSign=E:/temp/images/T280/sign/ serverPathSign=/test_layui/upload/sign/我们就把这个保存在如图所示:
在通过我们之前学过的映射，实际就是通过浏览器访问就相当于查询访问如图所示：
