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

<constant name="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

<%@ 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>

<%@ 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

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;
}
}

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

package com.struts2.service;
public interface LoginService {
boolean isLogin(String userName,String password);
}

package com.struts2.service;

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

写一个Service的实现

Java代码

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;
}
}

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

<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>

    <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

<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>

    <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。
