bootStrap Treeview插入+struts2+jQuery+ajax实现动态树

根据网上查询资料，经过测试，完成一个简单的树，涉及以下三个页面：tree.jsp

一、tree.jsp页面关键代码

1、引入文件

2、tree容器

3、js代码

//选择名称为treeview的DIV容器，加载树

$("#treeview")
   .treeview({
   data: "["+getNodesData()+"]",
   icon: "glyphicon glyphicon-stop",
   selectedIcon: "glyphicon glyphicon-stop",
   collapseIcon: "glyphicon glyphicon-minus",
   expandIcon: "glyphicon glyphicon-plus",
   color: "#000000",
   backColor: "#FFFFFF",
   showIcon: true,
   showCheckbox: false,
   onhoverColor: "#E8E8E8",
   showBorder: true,
   showTags: true,
   highlightSelected: true,
   highlightSearchResults: false,
   selectedBackColor: "#8D9CAA",
   levels: 3,
   tags: ['available'],
   onNodeSelected: function(event, data) { //选择节点后的事件处理代码
       alert("Hello");
   }
   });

二、Class类文件，实现数据读取，此处直接返回一个固定值，需进一步书写

package com.kehai.action;

import javax.servlet.http.HttpServletRequest;

import net.sf.json.JSONObject;

import org.apache.struts2.interceptor.ServletRequestAware;

import com.opensymphony.xwork2.ActionSupport;

public class TreeAction extends ActionSupport implements ServletRequestAware{
private static final long serialVersionUID = 1L;

   private HttpServletRequest request;
   private String result;

   public String getResult() {
       return result;
   }

   public void setResult(String result) {
       this.result = result;
   }

   public String getNodesData(){
       result="{text:'p1'}" ;
       JSONObject json = JSONObject.fromObject(result);
       result = json.toString();
       return SUCCESS;
   }

   public HttpServletRequest getRequest() {
       return request;
   }

   @Override
   public void setServletRequest(HttpServletRequest request) {
           this.request=request;
   }

}

三、struts.xml文件

       <action name="tree" class="com.kehai.action.TreeAction">
               <result type="json">
                  <param name="root">result</param>
                </result>
       </action>
