Struts2 小例子 --第二弹

apps：war格式的例子文件

lib：引用jar包文件

src：源码文件

docs：帮助文档

小例子：

1.创建web工程：struts

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app id="starter" version="2.4"
 3          xmlns="http://java.sun.com/xml/ns/j2ee"
 4          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 5          xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 6   
 7    <!-- START SNIPPET: filter -->
 8    <filter>
 9         <filter-name>struts2</filter-name>
10         <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
11     </filter>
12     <!-- START SNIPPET: filter -->
13   
14   <filter-mapping>
15       <filter-name>struts2</filter-name>
16       <url-pattern>/*</url-pattern>
17   </filter-mapping>
18   
19    <!-- Welcome file lists -->
20     <welcome-file-list>
21         <welcome-file>login.jsp</welcome-file>
22     </welcome-file-list>
23 </web-app>

WEB.xml

2.页面文件 login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'login.jsp' starting page</title>
    
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->

  </head>
  
  <body>
    
    <form action="login.action">
    
    username: <input type="text" name="username"><br>
    password: <input type="password" name="password"><br>
    age: <input type="text" name="age"><br>
    date: <input type="text" name="date"><br>
    
    <input type="submit" value="submit">
    
    </form>
       
  </body>
</html>

3.Struts配置文件(struts.xml默认是在src文件夹下)

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE struts PUBLIC
 3         "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
 4         "http://struts.apache.org/dtds/struts-2.5.dtd">
 5 <struts>
 6     
 7     <package name="struts2" extends="struts-default">
 8         <action name="login" class="com.shengsiyuan.struts2.LoginAction">
 9             <result name="success">/result.jsp</result>
10         </action>
11     </package>
12     
13 </struts>

struts.xml

4.调用文件

 1 package com.shengsiyuan.struts2;
 2 
 3 import java.util.Date;
 4 
 5 public class LoginAction
 6 {
 7     private String username;
 8     
 9     private String password;
10     
11     private int age;
12     
13     private Date date;
14     
15     public Date getDate()
16     {
17         return date;
18     }
19 
20     public void setDate(Date date)
21     {
22         this.date = date;
23     }
24 
25     public int getAge()
26     {
27         return age;
28     }
29 
30     public void setAge(int age)
31     {
32         this.age = age;
33     }
34 
35     public String getUsername()
36     {
37         return username;
38     }
39 
40     public void setUsername(String username)
41     {
42         this.username = username;
43     }
44 
45     public String getPassword()
46     {
47         return password;
48     }
49 
50     public void setPassword(String password)
51     {
52         this.password = password;
53     }
54     
55     public String execute()
56     {
57         return "success";
58     }
59 }

LoginAction

5.返回请求响应页

 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>My JSP 'result.jsp' starting page</title>
13     
14     <meta http-equiv="pragma" content="no-cache">
15     <meta http-equiv="cache-control" content="no-cache">
16     <meta http-equiv="expires" content="0">    
17     <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
18     <meta http-equiv="description" content="This is my page">
19     <!--
20     <link rel="stylesheet" type="text/css" href="styles.css">
21     -->
22 
23   </head>
24   
25   <body>
26    
27    username: ${requestScope.username }<br>
28    password: ${requestScope.password }<br>
29    age: ${requestScope.age }<br>
30    date: ${requestScope.date } 
31   </body>
32 </html>

result.jsp

代码结构

引用jar文件：struts-2.5.14.1-all.zip 文件中内容

额外注意：需要xwork-core-2.2.1.1.jar(不能上传文件)
