集成spring3

复制jar到WEB-INF/lib目录：
复制，并添加到java build path：

org.springframework.aop-3.1.0.M1.jar
org.springframework.asm-3.1.0.M1.jar
org.springframework.beans-3.1.0.M1.jar
org.springframework.context-3.1.0.M1.jar
org.springframework.core-3.1.0.M1.jar
org.springframework.expression-3.1.0.M1.jar
org.springframework.web-3.1.0.M1.jar

	aop:

============================================

配置applicationContext.xml，并配置LoginAction的bean

普通bean配置,注意加上scope="prototype"

注解方式配置：<context:component-scan base-package="org.skzr.demo"/>
applicationContext.xml:

<?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" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<bean id="loginAction" class="org.skzr.demo.action.LoginAction" scope="prototype"/>
	
	<context:component-scan base-package="org.skzr.demo"/>
</beans>

添加注解到LoginAction.java，注意：@Component("loginActionComponent") @Scope("prototype")

package org.skzr.demo.action;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

import com.opensymphony.xwork2.ActionSupport;

/**
 * 登录检测
 * @author <a href="mailto:skzr.org@gmail.com">skzr.org</a>
 * @version 1.0.0
 * @since JDK1.6
 */
@Component("loginActionComponent")
@Scope("prototype")
public class LoginAction extends ActionSupport {
	private static final long serialVersionUID = 1L;
	/** 用户名 */
	private String userName;
	/** 密码 */
	private String password;
	
	/**
	 * @return {@link #userName}
	 */
	public String getUserName() {
		return userName;
	}
	/**
	 * @param userName {@link #userName}
	 */
	public void setUserName(String userName) {
		this.userName = userName;
	}
	/**
	 * @return {@link #password}
	 */
	public String getPassword() {
		return password;
	}
	/**
	 * @param password {@link #password}
	 */
	public void setPassword(String password) {
		this.password = password;
	}

	/**
	 * 登录验证
	 * @return 验证后页面视图
	 */
	public String check() {
		return "admin".equals(userName) ? "welcome" : "success";
	}
}

修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">

	</filter-mapping>
	
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

启动web查看后台输出是不是正常初始化spring

修改struts.xml的action从spring中获取

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
	<package name="demo" extends="struts-default" namespace="/">
		<action name="loginAction" class="org.skzr.demo.action.LoginAction">
			<result>/WEB-INF/jsp/login.jsp</result>
			<result name="welcome">/WEB-INF/jsp/welcome.jsp</result>
		</action>
		<!-- 来自spring配置的bean -->
		<action name="loginActionSpring" class="loginAction">
			<result>/WEB-INF/jsp/login.jsp</result>
			<result name="welcome">/WEB-INF/jsp/welcome.jsp</result>
		</action>
		<!-- 来自spring注解配置的bean -->
		<action name="loginActionSpringComponent" class="loginActionComponent">
			<result>/WEB-INF/jsp/login.jsp</result>
			<result name="welcome">/WEB-INF/jsp/welcome.jsp</result>
		</action>
	</package>
</struts>

哈哈struts运行不正常了，无法使用spring的：

修改struts.properties添加spring支持：struts.objectFactory=spring
复制struts2-spring-plugin-2.2.3.jar到lib，并添加到java build path

重新运行系统即可正常登录了。
新的登录页面login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
