SSH整合過程

1.引入所需要的jar包
2.配置web.xml，增加struts2的所需要的過濾器配置。

         <filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
		<init-param>
			<param-name>config</param-name>
			<param-value>struts-default.xml,struts-plugin.xml,/resources/conf/struts.xml</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

3. 修改web.xml文件，配置Spring監聽器，和上下文變量。

<!-- 1、指定spring的配置文件，默認從web根目錄尋找配置文件， 我們可以通過spring提供的classpath:前綴指定從類路徑下尋找 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:/resources/conf/appContext*.xml</param-value>
	</context-param>
	<!-- 對Spring容器進行實例化 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

4. 編寫spring配置文件，配置管理hibernate的sessionFactory和事務管理、datasource等，以及actionBean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

	<!-- 配置數據庫信息 -->
	<!-- 數據庫連接池 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" 	destroy-method="close">
		<property name="driverClass" value="com.mysql.jdbc.Driver" />
		<property name="jdbcUrl"
			value="jdbc:mysql://localhost:3306/rabbit?useUnicode=true&characterEncoding=UTF-8" />
		<property name="user" value="rabbit" />
		<property name="password" value="19870924" />
		<!--初始化時獲取的連接數，取值應在minPoolSize與maxPoolSize之間。Default: 3 -->
		<property name="initialPoolSize" value="1" />
		<!--連接池中保留的最小連接數。 -->
		<property name="minPoolSize" value="1" />
		<!--連接池中保留的最大連接數。Default: 15 -->
		<property name="maxPoolSize" value="300" />
		<!--最大空閒時間,60秒內未使用則連接被丟棄。若爲0則永不丟棄。Default: 0 -->
		<property name="maxIdleTime" value="60" />
		<!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。Default: 3 -->
		<property name="acquireIncrement" value="5" />
		<!--每60秒檢查所有連接池中的空閒連接。Default: 0 -->
		<property name="idleConnectionTestPeriod" value="60" />
	</bean>


	<!-- 通過配置文件配置sessionFactory 
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="mappingResources">
			<list>
				<value>resources/conf/hibernate.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.format_sql">false</prop>
			</props>
		</property>
	</bean>-->
	<!-- 通過annotationSessionFactoryBean使用annotation-->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="packagesToScan">
			<value>com.**.entity.**</value>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.format_sql">false</prop>
			</props>
		</property>
	</bean>


	<!-- 事務控制 -->
	<bean id="transactionController"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>


	<!-- 使用攔截器進行事務控制 -->
	<bean id="transactionInterceptor"
		class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager">
			<ref bean="transactionController" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="save*">PROPAGATION_REQUIRED</prop>
				<prop key="update*">PROPAGATION_REQUIRED </prop>
				<prop key="add*">PROPAGATION_REQUIRED </prop>
				<prop key="execute*">PROPAGATION_REQUIRED </prop>
				<prop key="newTran*">PROPAGATION_REQUIRES_NEW</prop>
			</props>
		</property>
	</bean>


	<!-- 自動代理 -->
	<bean id="autoproxy"
		class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<list>
				<value>*Manager</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>
	<bean id="baseDao" class="com.base.dao.impl.BaseDAOImpl">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<bean id="baseManager" class="com.base.manager.impl.BaseManagerImpl">
		<property name="dao" ref="baseDao"></property>
	</bean>
</beans>

5. 配置hibernate配置文件，如果使用annotation，則配置entity
6. 配置struts2配置文件
