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。
