action处理如下
public void getNodeData() {
List<Map<String, Object>> nodedata = service.getNodes(this.getId());
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
Map<String, Object> tmp = null;

tmp.put("id", map.get("id"));
tmp.put("name", map.get("name"));
tmp.put("isParent",
Integer.valueOf(map.get("cnt").toString()) > 0 ? true
: false);
list.add(tmp);
}
try {
PrintWriter out;
JSONObject jo = new JSONObject();
response.setCharacterEncoding("gbk");
response.setContentType("text/html; charset=GBK");
out = response.getWriter();
System.out.println(JSONArray.fromObject(list).toString());
out.print(JSONArray.fromObject(list).toString());
out.close();
} catch (IOException e) {
e.printStackTrace();
}
