问jquery easyUI json格式问题，与struts2生成的 json问题

Question

jquery easyUI tree要的 json数据格式为：
[{
"id":1,
"text":"Folder1"
},{
"id":3,
"text":"Folder1"
},{
"id":"402884cf279834ad01279834afde0001","text":"一级"
}]

而我用struts2生成的 json格式为

action 代码:
private List> items;

public List<Map<String, Object>> getItems() {
    return items;
}

public void setItems(List<Map<String, Object>> items) {
    this.items = items;
}

public String list() {
    items = treeService.findNode("0");
    return "SUCCESS";
}

输入为：
{"items":[{"id":"402884cf278f43ff01278f4401bc0001","text":"一级","state":"closed"},{"id":"402884cf278f4dcc01278f4dd00d0001","text":"一级","state":"closed"},{"id":"402884cf278f4dd801278f4dda9d0001","text":"一级","state":"closed"},{"id":"402884cf279834a201279834a6030001","text":"一级","state":"closed"},{"id":"402884cf279834ad01279834afde0001","text":"一级","state":"closed"}]}

struts2生成的json带了个"items":所以tree不认这个数据格式，有啥办法能让他俩兼容一下呢，如果struts2生成的json不带"items":该怎么弄呢，谢谢

在action把object对象toString后（或者先转化为字符串），再把字符串（而不是对象）传输到前台
