上面呢，是jsp页面的代码，因为是纯插件测试，可以直接复制过去使用的，

action层代码，可以直接复制使用

public void getMenusById(){

List list=null;

try {

list=ztreeService.getMenusById(ztree);

} catch (Exception e) {

e.printStackTrace();

}

super.writeJson(list);

}

public List getMenusById(Ztree ztree) throws Exception;

//接口

//service代码，几本都可以复制使用

package com.jk.service.impl;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

@Override

public List queryList(Ztree ztree) throws Exception {

String hql=" from Ztree where 1=1 ";

//传的对象是否为空，拼接sql+id

if(ztree.getId()!=null){

hql+=" and id = :id ";

}

return ztreeDao.queryList(hql, params);

}

//递归查询
