本文介绍了一个使用Struts2与Spring框架整合的例子，包括登录页面的创建、配置文件的设置、Action及Service层的实现等步骤。

首先把spring和struts的jar包加进去，注意看jar包有没有冲突，否则tomcat可能启不来，在做本例的过程中，借鉴了一些网友的代码，在此表示感谢，本人开通这个博客，是用来做笔记，有不当之处，请踊跃提意见。

第一步：创建登陆页面login.jsp


<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>用户登陆</title>
</head>
<body>
    <s:form action="Login" method="post">
        <s:textfield name="userName" label="userName"></s:textfield>
        <s:password name="password" label="password"></s:password>
        <s:submit label="submit"></s:submit>
    </s:form>
</body>
</html>

第二步：创建返回页面result.jsp


<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    您的用户名是：<s:property value="userName"/><br/>
    您的密码是：<s:property value="password"/>
</body>
</html>

第三步：配置web.xml文件


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

	 <context-param>
	     <param-name>contextConfigLocation</param-name>
	     <param-value>classpath*:applicationContext*.xml</param-value>
	 </context-param>

     <filter>
         <filter-name>struts2</filter-name>
         <filter-class>
             org.apache.struts2.dispatcher.FilterDispatcher
         </filter-class>
     </filter>
     <filter-mapping>
         <filter-name>struts2</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>
     <listener>
         <listener-class>
             org.springframework.web.context.ContextLoaderListener
         </listener-class>
     </listener>
     <welcome-file-list>
         <welcome-file>index.html</welcome-file>
     </welcome-file-list>
 </web-app>

第四步：配置struts.xml文件


<!DOCTYPE struts PUBLIC
     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
     "http://struts.apache.org/dtds/struts-2.0.dtd">
 <struts>

     <package name="struts2" extends="struts-default">
        <action name="Login" class="loginAction">
            <result name="success">/s2/result.jsp</result>
            <result name="input">/s2/login.jsp</result>
        </action>
    </package>

 </struts>

第五步：配置application-hello.xml文件


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xmlns:aop="http://www.springframework.org/schema/aop"
		xmlns:tx="http://www.springframework.org/schema/tx"
		xsi:schemaLocation="
			http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
			http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
			http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

        <import resource="applicationContext-jdbc.xml"/>

        <bean id="loginService" class="cleversoft.struts2.s2s2.LoginServiceImpl"></bean>
        <bean id="loginAction" class="cleversoft.struts2.s2s2.LoginAction" scope="prototype">
            <property name="loginService" ref="loginService"></property>
        </bean>

</beans>

第六步：创建action文件LoginAction.java


package cleversoft.struts2.s2s2;

import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class LoginAction extends ActionSupport {
	private LoginService loginService;
	private String userName;
	private String password;
	public void setLoginService(LoginService loginService) {
		this.loginService = loginService;
	}
	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;
	}
	@Override
	public String execute() throws Exception {
		if(loginService.isLogin(userName, password))
			return SUCCESS;
		else
			return INPUT;
	}
}

第七步：创建service接口类LoginService.java


package cleversoft.struts2.s2s2;

public interface LoginService {
	boolean isLogin(String userName, String password);
}

第八步：创建service实现类LoginServiceImpl.java


package cleversoft.struts2.s2s2;

public class LoginServiceImpl implements LoginService {

	public boolean isLogin(String userName, String password) {
		if("marry".equals(userName) && "123".equals(password))
			return true;
		else 
			return false;
	}
}

第九步：运行tomcat，输入marry和123，返回如下页面表示成功


您的用户名是：marry
您的密码是：123
