请问jquery-easyui+struts2 实现tree的后台怎么实现

Question

1、前台
<br> $(function(){<br> $(&#39;#tt&#39;).tree({<br><br> url:&#39;menu2_find&#39;,<br> lines:true,<br> });<br> });<br>

Answer 1

public class Tree {

private int id;
private String text;
private boolean leaf;
private List children;
}

Action:
List trees = new ArrayList();

Tree root = new Tree();    
root.setText("root");  
root.setLeaf(false);    
root.setId(1);    
trees.add(root);    

List<Tree> childrenList = new ArrayList<Tree>();    
benzList.add...   

childrenList.setChildren(childrenList);    

JSONArray jsonObject = JSONArray.fromObject(trees); 

大概这样
