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

 <?xml version="1.0" encoding="UTF-8"?>

 <web-app id="starter" version="2.4"

          xmlns="http://java.sun.com/xml/ns/j2ee"

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <!-- START SNIPPET: filter -->

    <filter>

         <filter-name>struts2</filter-name>

         <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

     </filter>

     <!-- START SNIPPET: filter -->

   <filter-mapping>

       <filter-name>struts2</filter-name>

       <url-pattern>/*</url-pattern>

   </filter-mapping>

    <!-- Welcome file lists -->

     <welcome-file-list>

         <welcome-file>login.jsp</welcome-file>

     </welcome-file-list>

 </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)

 <?xml version="1.0" encoding="UTF-8"?>

 <!DOCTYPE struts PUBLIC

         "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"

         "http://struts.apache.org/dtds/struts-2.5.dtd">

 <struts>

     <package name="struts2" extends="struts-default">

         <action name="login" class="com.shengsiyuan.struts2.LoginAction">

             <result name="success">/result.jsp</result>

         </action>

     </package>

 </struts>

struts.xml

4.调用文件

 package com.shengsiyuan.struts2;

 import java.util.Date;

 public class LoginAction

 {

     private String username;

     private String password;

     private int age;

     private Date date;

     public Date getDate()

     {

         return date;

     }

     public void setDate(Date date)

     {

         this.date = date;

     }

     public int getAge()

     {

         return age;

     }

     public void setAge(int age)

     {

         this.age = age;

     }

     public String getUsername()

     {

         return username;

     }

     public void setUsername(String username)

     {

         this.username = username;

     }

     public String getPassword()

     {

         return password;

     }

     public void setPassword(String password)

     {

         this.password = password;

     }

     public String execute()

     {

         return "success";

     }

 }

LoginAction

5.返回请求响应页

 <%@ 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 'result.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>

    username: ${requestScope.username }<br>

    password: ${requestScope.password }<br>

    age: ${requestScope.age }<br>

    date: ${requestScope.date }

   </body>

 </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)

http://localhost:8080/struts2/login.jsp 访问地址
