Java Servlet生成JSON格式数据并用jQuery显示的方法 本文实例讲述了Java Servlet生成JSON格式数据并用jQuery显示的方法。分享给大家供大家参考，具体如下： 1、Servlet通过json-lib生成JSON格式的数据 import java.io.IOException; import java.io.PrintWriter; import java.util.*; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import json.Person; import net.sf.json.JSONArray; import net.sf.json.JSONObject; @WebServlet("/JSONServlet") public class JSONServlet extends HttpServlet { public JSONServlet() { super(); } public void destroy() { super.destroy(); // Just puts "destroy" string in log // Put your code here } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("application/x-json"); response.setCharacterEncoding("GBK"); PrintWriter out = response.getWriter(); ArrayList items=new ArrayList(); items.add(new Person(2,"jack")); items.add(new Person(2,"bob")); items.add(new Person(2,"alex")); JSONArray jsonArray=new JSONArray(); jsonArray.addAll(items); out.print(jsonArray.toString()); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request,response); } public void init() throws ServletException { // Put your code here } } 2、前端页面代码 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> Insert title here
jQuery也可以用.getJSON实现异步数据获取 希望本文所述对大家JSP程序设计有所帮助。
