Struts2+Spring2.5+Hibernate3.3整合开发附源代码

第一步在Spring中配置数据源：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
		<property name="driverClass" value="org.gjt.mm.mysql.Driver"/>
		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh2?useUnicode=true&amp;characterEncoding=UTF-8"/>
		<property name="user" value="root"/>
		<property name="password" value="hjc"/>
		<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->
		<property name="initialPoolSize" value="1"/>
		<!--连接池中保留的最小连接数。-->
		<property name="minPoolSize" value="1"/>	
		<!--连接池中保留的最大连接数。Default: 15 -->
		<property name="maxPoolSize" value="300"/>
		<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
		<property name="maxIdleTime" value="60"/>	
		<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->
		<property name="acquireIncrement" value="5"/>	
		<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->
		<property name="idleConnectionTestPeriod" value="60"/>
	</bean>

 第二步集成进hibernate ：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"/>
		 <property name="mappingResources">
			    <list>
			      <value>org/ssh2/bean/Employee.hbm.xml</value>
			    </list>
		</property>
		 <property name="hibernateProperties">
			 <value>
			      hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
			      hibernate.hbm2ddl.auto=update
			      hibernate.show_sql=false
			      hibernate.format_sql=false
			  </value>
		 </property>
	</bean>

 第三步使用Spring容器管理事务服务：

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"/>
	</bean>
	<!--使用基于注解方式配置事务 -->
	<tx:annotation-driven transaction-manager="txManager"/>
