本文介绍如何通过struts2-spring-plugin将Struts2与Spring框架进行整合，实现Struts2 Action的依赖注入。文章详细展示了配置过程，包括web.xml、struts2.xml和bean.xml等文件的具体设置。

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-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/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 >

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

</ listener >

< 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 >

< filter >

< 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" >

< struts >

< package name ="lee" extends ="struts-default" >

< action name ="login" class ="loginAction" >

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

< result name ="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" ?>

< beans xmlns ="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" >

< bean id ="myService" class ="lee.MyServiceImpl" />

< bean id ="loginAction" class ="lee.LoginAction" scope ="prototype" >

< property name ="ms" ref ="myService" />

</ bean >

</ beans >

LoginAction

package lee;

import com.opensymphony.xwork2.Action;

public class LoginAction implements Action ... {

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

package lee;

public interface MyService

... {

booleanvalid(Stringusername,Stringpass);

}

package lee;

public class MyServiceImpl implements MyService

... {

publicbooleanvalid(Stringusername,Stringpass)

...{System.out.println(username);

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

...{

returntrue;

}

returnfalse;

}

struts.properties

struts.i18n.encoding=gb2312
