一.导入jar包

<!--获取ServletAPI--><dependency>  <groupId>javaee</groupId>  <artifactId>javaee-api</artifactId>  <version>5</version></dependency><dependency>  <groupId>org.apache.struts</groupId>  <artifactId>struts2-core</artifactId>  <version>2.3.4.1</version></dependency><dependency>  <groupId>org.apache.struts.xwork</groupId>  <artifactId>xwork-core</artifactId>  <version>2.3.4.1</version></dependency>

二.web.xml

配置struts核心过滤器

<filter>  <filter-name>struts2</filter-name>  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter>  <filter-mapping>    <filter-name>struts2</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>

三.Action类

public class LoginAction implements Action {        private String name;        private String password;            public String execute() throws Exception {        if ("admin".equals(name)&&"123".equals(password)){            return "success";        }        return "input";    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }}

四.struts.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"        "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <constant name="struts.devMode" value="true"/>    <package name="default" namespace="/" extends="struts-default">         <action name="loginAction" class="cn.action.LoginAction">            <result name="success">/success.jsp</result>        </action>    </package></struts>

五.login.jsp页面

<%@page language="java" contentType="text/html; utf-8" %><%@taglib uri="/struts-tags" prefix="s"%><title>登录</title><html><body><s:form name="form1" namespace="/" method="POST" action="loginAction">    用户名：<s:textfield name="name"></s:textfield>    密码：  <s:textfield name="password"></s:textfield>    <s:submit value="登录"></s:submit></s:form></body></html>
