@红薯你好，想跟你请教个问题：

ztree 后台从webservece里面获取数据获取的数据类型是List<org>，org字段如下

private String id;
private String name;
private String desc;
List<Org> childOrg;

现在想递归List<org> 这个数据成Json格式，返回前台显示成树，求思路。

List<Org> list = null;
       DTAuthorityDataSourceFactory factory = new DTAuthorityDataSourceFactory();
       try {
           list = factory.getAuthorityDataSource("http://172.16.60.143/manager/rpc/ws/orgserver/getAllOrgInfo?wsdl").getAllOrgs();
       } catch (MalformedURLException e) {
          e.printStackTrace();
       }
       if (list.size()==0)
            {
              return null;
            }
        String orgs = list.toString();
        Document doc = StringUtils.parthStringXml(orgs);
        NodeList orgNodes = doc.getChildNodes();
        resolveOrgXml(orgNodes, orgs);
       System.out.println(list.size());
       PrintWriter out = response.getWriter();
       String str = JSON.toJSONString(list);
       System.out.println(JSON.toJSONString(str));
       out.print(new String(str.getBytes("utf-8"),"8859_1"));
       out.close();
       return null;
   }
   private void resolveOrgXml(NodeList orgNodes, Org parentOrg)
      {
        if (orgNodes.getLength() == 0)
        {
          return;
        }
        for (int i = 0; i < orgNodes.getLength(); i++)
        {
          Node tempNode = orgNodes.item(i);
          NamedNodeMap tempNnm = tempNode.getAttributes();
          String tempId = tempNnm.getNamedItem("id").getNodeValue();
          String tempName = tempNnm.getNamedItem("name").getNodeValue();
          Node tempDescNode = tempNnm.getNamedItem("desc");
          Org org = new Org();
          org.setId(tempId);
          org.setName(tempName);
          if (tempDescNode != null)
          {
            org.setDesc(tempDescNode.getNodeValue());
          }
          if (parentOrg == null)
          {
            this.orgs.add(org);
          } else {
            List childOrg = parentOrg.getChildOrg();
            if (childOrg == null)
            {
              childOrg = new ArrayList();
              childOrg.add(org);
              parentOrg.setChildOrg(childOrg);
            } else {
              parentOrg.getChildOrg().add(org);
            }
          }
          NodeList childNodeList = tempNode.getChildNodes();
          if ((childNodeList == null) || (childNodeList.getLength() <= 0))
            continue;
          resolveOrgXml(childNodeList, org);
        }
