SSH 框架整合（maven版本 xml配置方式 连接池c3p0）

如何整合Struts2 Hibernate 和Spring 首先你必须了解三个框架是如何独立运行的：
代码下载：http://download.csdn.net/detail/zhanglinlang/9775160

Struts2 是通过在web.xml 中 Filter拦截器来启动自己的核心类StrutsPrepareAndExecuteFilter，完成事件的分发。

Spring 是通过 在web.xml 注册监听器来监听ContextLoaderListener，监听web应用的启动事件来完成自己的框架启动工作。

Hibernate 是通过创建SessionFactory工厂手动加载配置文件来完成启动工作，Hibernate是可以通过代码创建SessionFactory，就可以交给Spring通过ioc来控制该类的实例化。

下面就是整合代码：目录结构如下

首先在resource目录下创建 config目录方便管理：
首先配置
Hibernate ：

<hibernate-configuration>
    <session-factory name="foo">

        
        <property name="hibernate.show_sql">trueproperty>
        <property name="hibernate.format_sql">trueproperty>
        
        <property name="hbm2ddl.auto">updateproperty>

        
        <property name="connection.isolation">4property>

        
        
        
        

        
        <mapping resource="com/zll/entity/User.hbm.xml"/>
        <mapping resource="com/zll/entity/Student.hbm.xml"/>

    session-factory>
hibernate-configuration>

Struts.xml

<struts>
     <package name="person" namespace="/" extends="struts-default">
        
        <action name="userAction" class="userAction" />
     package>
struts>

Spring.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

    <tx:annotation-driven transaction-manager="transactionManager"/>

    
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate">
        <property name="sessionFactory" ref="sessionFactory">property>

    <import resource="classpath:config/testTemple.xml"/>

testTemple.xml（这个不重要，看看如何配置就行）

整合细节知识点(了解)：
Struts2 和 Spring整合：就是将action的创建交由Spring管理。配置文件中class只需要配置Spring中bean的id就可以。

 name="userAction" class="SpringBeanId" />

Hibernate和Spring整合：
1、创建连接池的对象交由spring管理
2、Spring提供了SessionFactory的封装类LocalSessionFactory，配置该类，并将数据源配置给它。
3、配置Spring的HibernateTemplate，将SessionFactory配置给他。替代session完成数据操作。
4、spring 事务管理配置，替代Hibernate事务管理
