在H5里面写好程序接口，这儿使用的是Hbuilder软件

在index文件里面写如下代码

<!DOCTYPE html><html><head>    <meta charset="utf-8">    <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />    <title></title>    <script src="js/mui.min.js"></script>    <link href="css/mui.min.css" rel="stylesheet"/></head><body><script>mui.plusReady(function(){     mui.ajax('http://10.5.15.10:8080/test/servlet/test',{data:{category:'news'},dataType:'json',//服务器返回json格式数据type:'post',//HTTP请求类型 ......success:function(data){alert(data.result);}});});</script></body></html>

在web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <display-name></display-name>  <servlet>    <description>This is the description of my J2EE component</description>    <display-name>This is the display name of my J2EE component</display-name>    <servlet-name>test</servlet-name>    <servlet-class>com.test.test</servlet-class>  </servlet>  <servlet-mapping>    <servlet-name>test</servlet-name>    <url-pattern>/servlet/test</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

在java中写好

package com.test;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class test extends HttpServlet {/** * Constructor of the object. */public test() {super();}/** * Destruction of the servlet. <br> */public void destroy() {super.destroy(); // Just puts "destroy" string in log// Put your code here}/** * The doGet method of the servlet. <br> * * This method is called when a form has its tag value method equals to get. *  * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {this.doPost(request, response);}/** * The doPost method of the servlet. <br> * * This method is called when a form has its tag value method equals to post. *  * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {//response.setContentType("text/html");PrintWriter out = response.getWriter();out.println("{\"result\":\"sucess\"}");out.flush();out.close();}/** * Initialization of the servlet. <br> * * @throws ServletException if an error occurs */public void init() throws ServletException {// Put your code here}}
