List類型轉換成JSON

Java代碼塊：List<User> list = new ArrayList<User>();User user = new User();user.setId("1");user.setName("aaa");list.add(user);JSONObject userJSON = new JSONObject();try {for (Iterator iterator = list.iterator(); iterator.hasNext();) {User user = (User) iterator.next();userJSON.put("id", user.getId());userJSON.put("name", user.getName());}} catch (JSONException e) {e.printStackTrace();}request.setAttribute("userJSON", userJSON);JSP代碼塊：var userJSON = ${requestScope.userJSON};for(temp in cateJSON){  var str = temp.id + ' ' +temp.name;  alert(str);}
