这是用jquery ztree做的二级权限树，互联二版代码，原理主要：
1.框架基于struts2、spring3、ibatIS2.3
2.主要是TEmployeePriv表的三个字段(PRIV_NUM、MENU_ID_1、PRIV_TYPE)：
?? privNum为id(子id)，menuId1为pId(父id)，
?? privType为权限菜单类型[权限菜单(60),权限集合(61),权限动作(62)]即60一级菜单、61二级菜单、62三级菜单
?
一、action代码
/**
* 打开授权
*/
public String openImpower()
{
role = service.queryById(roleNum);
TRolePriv rp = new TRolePriv();
rp.setRoleNum(roleNum);
List<TRolePriv> rpList = service.queryRolePriv(rp);//权限中间表List
List<TEmployeePriv> privList = service.queryAllPriv(new TEmployeePriv());//查询所有TEmployeePriv
/**合成权限树*/
List<PrivJSON> jsonList = new ArrayList<PrivJSON>();
for( TEmployeePriv priv : privList ){
if("60".equals(priv.getPrivType())){
PrivJSON json = new PrivJSON();//一级菜单
json.setId(priv.getPrivNum());
json.setpId("0");
json.setName(priv.getPrivName());
json.setOpen(false);//默认不展开
jsonList.add(json);
}
else{
PrivJSON json2 = new PrivJSON();
json2.setId(priv.getPrivNum());
json2.setpId(priv.getMenuId1());
json2.setName(priv.getPrivName());
json2.setPrivNum(priv.getPrivNum());
for(TRolePriv trp : rpList){
if(trp.getPrivNum().equals(priv.getPrivNum())){
json2.setOpen(false);//默认不展开
json2.setChecked(true);
}
}
jsonList.add(json2);
}
}
JSONArray myjsonObj = JSONArray.fromObject(jsonList);//将权限集合，转成JSON数组
this.getRequest().setAttribute("myjsonObj",myjsonObj);
successPath = "/jsp/phone/priv/role/impowerRole.jsp";
return SUCCESS;
}
?
二、jsp页面代码
