Struts2和Spring整合,创建一个OA工程
1、整合struts2
1)导入strut2的jar包:commons-logging-1.0.4.jar,freemarker-2.3.8.jar,ognl-2.6.11.jar,struts2-core-2.0.12.jar,xwork-2.06.jar。暂时导入这些jar包，到时候需要再倒入。
2)将struts.xml文件放置在OA工程的src目录下。
3)在web.xml里面配置struts2用到的核心过滤器。

Xml代码

<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>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>

2、整合spring
1)导入spring的jar包:spring.jar
2)将applicationContext.xml文件放置在OA工程的WEB-INF目录下。
3)在web.xml里面配置spring用到的监听器。

Xml代码

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

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

4)添加struts2-spring整合的插件:struts2-spring-plugin-2.0.12.jar,如果不使用这个插件，则需要在struts.xml里面配置:

Xml代码

<constantname="struts.objectFactory"value="org.apache.struts2.spring.StrutsSpringObjectFactory"/>

<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />

3、测试struts2和spring整合对不对?
写一个jsp页面login.jsp来测试:

Html代码

<%@pagelanguage="java"contentType="text/html;charset=UTF-8"pageEncoding="UTF-8"%>
<%@taglibprefix="s"uri="/struts-tags"%>
<!DOCTYPEhtmlPUBLIC"-//W3C//DTDHTML4.01Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<metahttp-equiv="Content-Type"content="text/html;charset=UTF-8">
<title>Inserttitlehere</title>
</head>
<body>
<s:formaction="Login"method="post">
<s:textfieldname="userName"label="userName"></s:textfield>
<s:passwordname="password"label="password"></s:password>
<s:submitlabel="submit"></s:submit>
</s:form>
</body>
</html>

<%@ 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>
    <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>

写一个LoginAction

Java代码

packagecom.struts2.action;
importcom.opensymphony.xwork2.ActionSupport;
importcom.struts2.service.LoginService;
publicclassLoginActionextendsActionSupport{
privateLoginServiceloginService;
privateStringuserName;
privateStringpassword;
publicvoidsetLoginService(LoginServiceloginService){
this.loginService=loginService;
}
publicStringgetUserName(){
returnuserName;
}
publicvoidsetUserName(StringuserName){
this.userName=userName;
}
publicStringgetPassword(){
returnpassword;
}
publicvoidsetPassword(Stringpassword){
this.password=password;
}
@Override
publicStringexecute()throwsException{
if(loginService.isLogin(userName,password))
returnSUCCESS;
else
returnINPUT;
}
}

package com.struts2.action;

import com.opensymphony.xwork2.ActionSupport;
import com.struts2.service.LoginService;
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;
	}
}

写一个Service

Java代码

packagecom.struts2.service;
publicinterfaceLoginService{
booleanisLogin(StringuserName,Stringpassword);
}

package com.struts2.service;

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

写一个Service的实现

Java代码

packagecom.struts2.service.impl;
importcom.struts2.service.LoginService;
publicclassLoginServiceImplimplementsLoginService{
publicbooleanisLogin(StringuserName,Stringpassword){
if("hello".equals(userName)&&"world".equals(password))
returntrue;
else
returnfalse;
}
}

package com.struts2.service.impl;

import com.struts2.service.LoginService;
public class LoginServiceImpl implements LoginService {

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

在struts.xml里面配置:

Xml代码

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

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

在applicationContext.xml里面配置:

Xml代码

<beanid="loginService"class="com.struts2.service.impl.LoginServiceImpl"></bean>
<beanid="loginAction"class="com.struts2.action.LoginAction"scope="prototype">
<propertyname="loginService"ref="loginService"></property>
</bean>

    <bean id="loginService" class="com.struts2.service.impl.LoginServiceImpl"></bean>
    <bean id="loginAction" class="com.struts2.action.LoginAction" scope="prototype">
        <property name="loginService" ref="loginService"></property>
    </bean>

启动tomcat，分别输入hello和world，提交,结果为hello和world。说明struts2和spring整合成功。
