整合Spring，换句话说，也就是让spring的IOC功能为我们的struts action注入逻辑组件

首先需要加载struts2-spring-plugin-2.0.6.jar这个包，这个是关键，他可以帮我们把struts2和spring仅仅整合在一起

首先是web.xml

<?xmlversion="1.0"encoding="utf-8"?>

<web-appversion="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/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/bean.xml</param-value>

</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<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>

<filter-name>aaa</filter-name>

<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>

</filter>

<filter-mapping>

<filter-name>aaa</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</web-app>

其次是struts2.xml

<?xmlversion="1.0"encoding="GBK"?>

<!DOCTYPEstrutsPUBLIC

"-//ApacheSoftwareFoundation//DTDStrutsConfiguration2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<packagename="lee"extends="struts-default">

<actionname="login"class="loginAction">

<resultname="error">/error.jsp</result>

<resultname="success">/welcome.jsp</result>

</action>

</package>

</struts>

最关键的是bean.xml，完成为struts2 action的注入

<?xmlversion="1.0"encoding="GBK"?>

<beansxmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd">

<beanid="myService"class="lee.MyServiceImpl"/>

<beanid="loginAction"class="lee.LoginAction"scope="prototype">

<propertyname="ms"ref="myService"/>

</bean>

</beans>

LoginAction

packagelee;

importcom.opensymphony.xwork2.Action;

publicclassLoginActionimplementsAction{

privateStringusername;

privateStringpassword;

privateStringtip;

privateMyServicems;

publicStringgetUsername(){

returnusername;

}

publicvoidsetUsername(Stringusername){

this.username=username;

}

publicStringgetPassword(){

returnpassword;

}

publicvoidsetPassword(Stringpassword){

this.password=password;

}

publicStringgetTip(){

returntip;

}

publicvoidsetTip(Stringtip){

this.tip=tip;

}

publicStringexecute()throwsException{

if(ms.valid(this.getUsername(),this.getPassword())){

returnSUCCESS;

}

else{

returnERROR;

}

publicMyServicegetMs(){

returnms;

}

publicvoidsetMs(MyServicems){

this.ms=ms;

}

MyService及实现

packagelee;

publicinterfaceMyService

{

booleanvalid(Stringusername,Stringpass);

}

packagelee;

publicclassMyServiceImplimplementsMyService

{

publicbooleanvalid(Stringusername,Stringpass)

{System.out.println(username);

if(username.equals("高")&&pass.equals("1234"))

{

returntrue;

}

returnfalse;

}

struts.properties

struts.i18n.encoding=gb2312

　　 <%@ page contentType="text/html; charset=gb2312"%>

welcome.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>成功页面</title>
</head>
<body>
您已经登录!
<s:property value="username"/>
<s:property value="tip"/>
</body>
</html>

error.jsp

<%@ page language="java" contentType="text/html; charset=GBK"%>
<html>
<head>
<title>错误页面</title>
</head>
<body>
