1. 本示例在第一篇架构基础上添加代码
2. 首先，在dwr.xml文件里添加对象转换器
3. 编写Person实体类
1 package com.skyer.vo; 2 3 import java.util.Arrays; 4 5 public class Person { 6 private String name; 7 private int age; 8 private String[] hobby; 9 10 public String getName() { 11 return name; 12 } 13 public void setName(String name) { 14 this.name = name; 15 } 16 public int getAge() { 17 return age; 18 } 19 public void setAge(int age) { 20 this.age = age; 21 } 22 public String[] getHobby() { 23 return hobby; 24 } 25 public void setHobby(String[] hobby) { 26 this.hobby = hobby; 27 } 28 29 @Override 30 public String toString() { 31 return "Person [name=" + name + ", age=" + age + ", hobby=" + Arrays.toString(hobby) + "]"; 32 } 33 }
4. 在核心控制器（CoreServlet.java）里添加如下方法：
1 public Person printPerson(Person person) { 2 System.out.println(person); 3 return person; 4 }
5. 编写测试的jsp页面：
1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 2 <% 3 String path = request.getContextPath(); 4 String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; 5 %> 6 7 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 8 <html> 9 <head> 10 <base href="<%=basePath%>"> 11 12 <title>dwr</title> 13 <script type=‘text/javascript‘ src=‘dwr/engine.js‘></script> 14 <script type=‘text/javascript‘ src=‘dwr/util.js‘></script> 15 <script type=‘text/javascript‘ src=‘dwr/interface/CoreServlet.js‘></script> 16 </head> 17 <body> 18 <div style="margin-top: 20px" align="center"> 19 <button onclick="printPerson();">点击</button> 20 </div> 21 </body> 22 <script type="text/javascript"> 23 function printPerson() { 24 var person = { 25 name: "skyer", 26 age: 18, 27 hobby: [ "爱好1", "爱好2", "爱好3" ] 28 }; 29 30 CoreServlet.printPerson(person, function(data) { 31 alert(data.name + ":" + data.age + ":" + data.hobby); 32 }); 33 } 34 </script> 35 </html>
6. 测试
