前段时间，实习时候接到一个任务，将原有后台处理留言的的所有的一级分类改版成一级分类二级分类，在试验了大半个月之后，终于用treetable勉强的实现了，上面的一章节已经说过了，但是项目经理说我那个实现的不能拖动排序，哎，人为刀俎，我为鱼肉，没办法，硬着头皮换，幸好组里有一个项目经理的帮忙实现了easyUI treegrid 现在将流程大致的步骤记录在案，以防遗忘。公司的项目是ssh三层框架，现在我对这个业务流程还是不太熟悉，准备这几天系统的看看怎么样实现的这个框架，然后再结合实际的案例做一个简单的demo，时间过的太快了，马上研究生就要开题了，我现在什么都没准备，要看看自然语言处理的一些方面的内容了，现在真是会的东西太少，要学的东西太多 首先我们改动的是后台处理分类的catalogAction 代码如下

前台方面我们引入了easyUI treegrid 包，然后在此基础上改动 下面是 catalogList.jsp 页面
<%@page import="com.trs.space.comment.Constants"%>
<%@page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
<%@include file="/WEB-INF/jsp/include/taglibs.jsp"%>
留言分类浏览
后台管理 >> 留言分类浏览
<%UserInfo info = (UserInfo) request.getSession().getAttribute(Constants.BIND_USER_INFO); %><%=info.getAdminUser().getNickName() %>
<%@include file="include/left_navigate.jsp" %>
<%@include file="include/foot_version.jsp/" %>
其中还有一个编辑的页面的实现 catalogEdit.jsp
<%@page import="com.trs.space.comment.Constants"%>
<%@page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
<%@include file="/WEB-INF/jsp/include/taglibs.jsp"%>

添加/修改留言分类
添加一个新的留言分类或者修改一个已有的留言分类。

能够实现一级拖拽 二级隐藏一级二级拖拽了
