**一、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-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-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

**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 4.01Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Insert title here</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>

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 LoginServiceloginService;

private StringuserName;

private Stringpassword;

public voidsetLoginService(LoginService loginService) \{

this.loginService =loginService;

public StringgetUserName() \{

return userName;

public voidsetUserName(String userName) \{

this.userName =userName;

public StringgetPassword() \{

return password;

public voidsetPassword(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(StringuserName,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 booleanisLogin(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

<actionname="Login" class="loginAction">

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

<resultname="input">/login.jsp</result>

</action>

</package>

在applicationContext.xml里面配置:

Xml代码

<propertyname="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。**

**Struts+Spring整合实现，接下来继续整合Hibernate**

前面已经讲述了Struts2+Spring整合，这里我们接着整合Hibernate  
整合Hibernate  
**1)****导入Hibernate3.1的jar包**:antlr-2.7.6.jar,commons-collections-3.1.jar,dom4j-1.6.1.jar,javassist-3.4.GA.jar,jta-1.1.jar,hibernate3.jar,slf4j-api-1.5.6.jar,slf4j-log4j12-1.5.6.jar,log4j-1.2.13.jar。暂时导入这些jar包，到时候需要再倒入。  
**2)****将spring的配置文件applicationContext-\*.xml文件放置在OA工程的src目录下**,这里我们有三个：  
applicationContext-action.xml,applicationContext-beans.xml,applicationContext-common.xml  
**3)****在web.xml里面配置**

Xml代码

<context-param>

<param-name>contextConfigLoaction</param-name>

<param-value>classpath\*:applicationContext-\*.xml</param-value>

</context-param>

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

</listener>

<filter-name>hibernateFilter</filter-name>

<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>hibernateFilter</filter-name>

<url-pattern>\*.action</url-pattern>

</filter-mapping>

<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>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>utf-8</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

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

</filter-mapping>

**4)spring****里面有声明式事务，它对hibernate做了封装，在applicationContext-common.xml里面配置spring的声明式事务:**

Xml代码

<beanid="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<propertyname="configLocation">

<value>classpath:hibernate.cfg.xml</value>

</property>

</bean>

<beanid="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<propertyname="sessionFactory">

<refbean="sessionFactory"/>

</property>

</bean>

<tx:adviceid="txAdvice"transaction-manager="transactionManager">

<tx:attributes>

<tx:methodname="add\*" propagation="REQUIRED"/>

<tx:methodname="delete\*" propagation="REQUIRED"/>

<tx:methodname="modify\*" propagation="REQUIRED"/>

<tx:methodname="\*" read-only="true"/>

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcutid="allManagerMethod" expression="execution(\*com.struts2.server.\*.\*(..))"/>

<aop:advisorpointcut-ref="allManagerMethod"advice-ref="txAdvice"/>

</aop:config>

用到了spring的aop,所以在applicationContext.xml配置文件中引入spring-aop.xsd。具体如下：

<beans

xmlns=*"http://www.springframework.org/schema/beans"*

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

xmlns:p=*"http://www.springframework.org/schema/p"*

xmlns:aop=*"http://www.springframework.org/schema/aop"*

xmlns:tx=*"http://www.springframework.org/schema/tx"*

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.xsd*

*       http://www.springframework.org/schema/aop                       http://www.springframework.org/schema/aop/spring-aop.xsd"*>  
  
**5)****测试Struts2+Spring+Hibernate整合是否成功**  
**第一步：测试Spring+Hibernate整合是否成功**  
写一个需要映射的值对象Person

Java代码

package com.oa.model;

/\*\*

\* @author lukuijun@hanqinet.com

\* @hibernate.classtalbe="t\_person"

\*/

public class Person \{

/\*\*

\* @hibernate.idgenerator-class="native"

\*/

private int id;

/\*\*

\* @hibernate.property

\*/

private String name;

/\*\*

\* @hibernate.property

\*/

private String sex;

/\*\*

\* @hibernate.property

\*/

private Stringaddress;

/\*\*

\* @hibernate.property

\*/

private String duty;

/\*\*

\* @hibernate.property

\*/

private String phone;

/\*\*

\* @hibernate.property

\*/

private Stringdescription;

public int getId() \{

return id;

public void setId(int id)\{

this.id = id;

public String getName()\{

return name;

public void setName(Stringname) \{

this.name = name;

public String getSex()\{

return sex;

public void setSex(Stringsex) \{

this.sex = sex;

public String getAddress()\{

return address;

public voidsetAddress(String address) \{

this.address =address;

public String getDuty()\{

return duty;

public void setDuty(Stringduty) \{

this.duty = duty;

public String getPhone()\{

return phone;

public voidsetPhone(String phone) \{

this.phone =phone;

public StringgetDescription() \{

returndescription;

public voidsetDescription(String description) \{

this.description =description;

运行ant生成Person.hbm.xml映射文件:

Xml代码

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/HibernateMapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<classtable="t\_person" name="com.oa.model.Person">

<idaccess="field" name="id">

<generatorclass="native"/>

</id>

<propertyname="sex" access="field"/>

<propertyname="address" access="field"/>

<propertyname="duty" access="field"/>

<propertyname="phone" access="field"/>

<propertyname="description" access="field"/>

</class>

</hibernate-mapping>

运行ant生成hiberante.cfg.xml文件:

Xml代码

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE hibernate-configuration PUBLIC"-//Hibernate/Hibernate Configuration DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<propertyname="hibernate.connection.driver\_class">com.mysql.jdbc.Driver</property>

<propertyname="hibernate.connection.url">jdbc:mysql://localhost:3306/oa</property>

<propertyname="hibernate.connection.username">root</property>

<propertyname="hibernate.connection.password">hanqinet</property>

<propertyname="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

<propertyname="hibernate.hbm2ddl.auto">update</property>

<mappingresource="com/oa/model/Person.hbm.xml"/>

</session-factory>

</hibernate-configuration>

接着启动Tomcat,启动完毕检查数据库里面新增加了表t\_person，Spring2+Hibernate整合成功  
**第二步：测试Struts2+Spring整合是否成功**  
参考一、Struts2+Spring整合，测试成功  
**完成这个两步成功，说明我们的框架整合成功！**
