最重要的文件：struts-config.xml配置文件
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
"http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
<form-beans name="loginFrom" type=""></form-beans>
<action-mappings>
<action path="/login" name="loginFrom" type="">
<forward name="loginSuccess" path="/loginSuccess.jsp"></forward>
<forward name="loginFailure" path="/loginFailure.jsp"></forward>
</action>
</action-mappings>
</struts-config>
Web.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

登录界面 login.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'login.jsp' starting page</title>
</head>
<body>
<form action="<%=request.getContextPath()%>/login.do" method="post">
username ： <input type="text" name="username"><br><br>
password ： <input type="text" name="password"><br><br>
<input type="submit" value="login">
</form>
</body>
</html>
登录成功后的界面loginSuccess和失败后的界面loginFailure在这里不再赘述，就是输出成功或失败的两句话。
From文件，相当于javabean
package itcast.family.cn;
import org.apache.struts.action.ActionForm;
public class LoginFrom extends ActionForm {
private String userName = null;
private String password = null;
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;
}
}
Action文件，相当于servlet
package itcast.family.cn;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class LoginAction extends Action {
//execute是现在struts2常用方法，以前老版本的叫做：perform
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
//第一步强制转换为自己的类
LoginFrom loginFrom = (LoginFrom)form;
//业务逻辑处理
String returnURLKeyWord = null;
if(loginFrom.getUserName().equals("yangkai")){
returnURLKeyWord ="loginSuccess";
}else{
returnURLKeyWord ="loginFailure";
}
//跳转关键字
return mapping.findForward(returnURLKeyWord);
}
}
