Struts2入门教程

最近闲来无事，学习s2sh框架，这里先写一点struts2的入门

我的环境

eclipse 4.3.2

tomcat 7.0.52

jdk 1.7.0_45

struts2 2.3.16.3

在eclipse中配置好tomcat，安装好struts2（将基本jar包拷到WebContent-->WEB-INFO-->lib中）

在WEB-INFO中配置好web.xml（可以在struts2的apps里面找到，修改一下）注意web.xml的路径

web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app id="WebApp_9" 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">
 3     <filter>
 4         <filter-name>struts2</filter-name>
 5         <!--  <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>-->
 6         <!-- org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter -->
 7         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
 8     </filter>
 9 
10     <filter-mapping>
11         <filter-name>struts2</filter-name>
12         <url-pattern>/*</url-pattern>
13     </filter-mapping>
14     <welcome-file-list>
15         <welcome-file>index.jsp</welcome-file>
16     </welcome-file-list>
17 
18 </web-app>

在WebContent下面新建一个login.jsp页面

login.jsp

 1 <%@ page language="java" contentType="text/html; charset=UTF-8" import="java.util.*"
 2     pageEncoding="UTF-8"%>
 3 <%@ taglib uri="/struts-tags" prefix="s" %>
 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 5 <html>
 6 <head>
 7 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
 8 <title>Login Page</title>
 9 </head>
10 <body>
11     <s:form action="login" method="post" >
12         <s:textfield name="username"/>
13         <s:textfield name="password" type="password"/>
14         <s:submit value="login"/>
15     </s:form>
16 </body>
17 </html>

新建一个Action类，这里我建的类路径为com.gxf.struts2.LoginAction

LoginAction.java

 1 package com.gxf.struts2;
 2 
 3 import com.opensymphony.xwork2.ActionSupport;
 4 
 5 @SuppressWarnings("serial")
 6 public class LoginAction extends ActionSupport {
 7     private String username;
 8     private String password;
 9     @Override
10     public String execute() throws Exception {
11         if(username.equals("luckygxf") && password.equals("luckygxf")){
12             return SUCCESS;
13         }
14         else{
15             return INPUT;
16         }
17     }
18     
19     public String getUsername() {
20         return username;
21     }
22     public void setUsername(String username) {
23         this.username = username;
24     }
25     public String getPassword() {
26         return password;
27     }
28     public void setPassword(String password) {
29         this.password = password;
30     }
31     
32     
33 }

在src目录下面新建一个struts.xml（这里也可以在下载的struts2中找到，修改一下就可以了）

struts.xml

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE struts PUBLIC
 3     "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
 4     "http://struts.apache.org/dtds/struts-2.3.dtd">
 5 
 6 <struts>
 7     <package name="login" namespace="/" extends="struts-default">
 8         <action name="login" class="com.gxf.struts2.LoginAction">
 9             <result name="success">/success.jsp</result>
10             <result name="input">/login.jsp</result>
11         </action>
12 
13     </package>
14 
15 </struts>

在WebContent下面新建一个success.jsp页面

success.jsp

 1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
 2     pageEncoding="ISO-8859-1"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
 7 <title>success.jsp</title>
 8 </head>
 9 <body>
10     <h1>success.jsp</h1>
11 </body>
12 </html>

ok，所有的配置已经写好。将项目部署到tomcat中，启动tomcat。查看控制台的输出信息，没有错误。在浏览器中输入http://localhost:8080/Struts2/login.jsp

用户名和秘密都输入luckygxf。登陆成功，跳转到success.jsp页面。
