后台接收主要代码：

//设置请求编码
req.setCharacterEncoding("UTF-8");
//获取编辑数据这里获取到的是json字符串
String deleted = req.getParameter("deleted");
String inserted = req.getParameter("inserted");
String updated = req.getParameter("updated");

if(deleted != null){
    //把json字符串转换成对象
    List<Bean> listDeleted = JSON.parseArray(deleted, Bean.class);
    //TODO 下面就可以根据转换后的对象进行相应的操作了
}

if(inserted != null){
//把json字符串转换成对象
List<Bean> listInserted = JSON.parseArray(inserted, Bean.class);
}

if(updated != null){
//把json字符串转换成对象
List<Bean> listUpdated = JSON.parseArray(updated, Bean.class);
}
