DWR第四篇之对象传参

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>
