ajax动态加载json数据并详细解析

效果图

jsp代码

servlet代码

//get
public void doGet(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {

  response.setContentType("text/html");
  response.setCharacterEncoding("utf-8");
  response.setContentType("text/html;charset=utf-8");
  String name = request.getParameter("name");
  String age = request.getParameter("age");
  if (name == null || name == "") {
   name = "测试名字admin";
  }

  if (age == null || age == "") {
   age = "测试年龄100";
  }
  user user = new user(1, name, age);
  PrintWriter out = response.getWriter();

  JSonObject jsonObj = JSONObject.fromObject(user);

  out.print(jsonObj);

  out.flush();
  out.close();
 }

//post
public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {

  // response.setContentType("text/html");

  request.setCharacterEncoding("utf-8");
  response.setCharacterEncoding("utf-8");
  response.setContentType("text/html;charset=utf-8");
  String name = request.getParameter("name");
  if (name == null || name == "") {
   name = "测试名字admin";
  }
  String age = request.getParameter("age");
  if (age == null || age == "") {
   age = "测试年龄100";
  }
  user user = new user(1, name, age);
  PrintWriter out = response.getWriter();

  JSonObject jsonObj = JSONObject.fromObject(user);

  out.print(jsonObj);

  out.flush();
  out.close();
 }
