JSON解析

服务器端：

ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();

HashMap<String,String> map1 = new HashMap<String,String>();
map1.put("name","violet");
map1.put("sex","nv");
list.add(map1);
JSONObject jo = new JSONObject();
jo.put("stulist",list);

PrintWriter pw = response.getWriter();
pw.priintln(jo);
pw.flush();
pw.close();

客户端：

JSONObject jo = new JSONObjet(data);

JSONArray ja = jo.getJSONArray();

for(int i=0;i<ja.length();i++){
    JSONObject jtemp = ja.getJSONObject(i);
    String name = jtemp.getString("name");
    String sex = jtemp.getString("sex");
}
