权限管理（java+struts2(自定义标签)实现）--------->全代码演示

地址：http://blog.chinaunix.net/uid-24343152-id-3673026.html

最近由于项目不是很紧所以总结了之前做了n遍的权限管理功能。以便之后系统copy之用。
之前做过权限绑定给具体人的操作，而这次做的是权限绑定给角色，人员去选择角色。
废话不多说,先看效果
1.页面展示(新建角色，绑定权限)

2.权限管理数据库设计

3. 页面代码
注意：此处tree用到的dtree,基于javascript写的。而本人用过zTree后更推荐使用ztree，基于jquery的代码（功能点多，api详细）
因此必须先下载dtree，此处省略下载。

下载后将dtree自带的css和图片存放在项目制定路径下。

本人主要修改了dtree的js代码：实现checkbox，和异步访问功能
