Spring 与 Hibernate集成

1)加载需要的properties配置文件
applicationContext.xml (spring2.5.6)

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" 
	parent="properties"
/>

<bean id="properties"
	class="org.springframework.beans.factory.config.PropertiesFactoryBean">
	<property name="locations">
		<list>
			<value>classpath:database.properties</value>
		</list>
	</property>
</bean>

applicationContext.xml (spring3.0.5)

<context:property-placeholder location="classpath:database.properties" />

2)数据源配置(c3p0) (仅供参考建议使用BoneCP)
applicationContext.xml

<bean id="dataSource"  
	class="com.mchange.v2.c3p0.ComboPooledDataSource"  
	destroy-method="close">  
	<property name="driverClass" value="${jdbc.driverClass}" />  
	<property name="jdbcUrl" value="${jdbc.url}" />  
	<property name="user" value="${jdbc.username}" />  
	<property name="password" value="${jdbc.password}" />  
	<property name="minPoolSize" value="${c3p0.minPoolSize}" />  
	<property name="maxPoolSize" value="${c3p0.maxPoolSize}" />  
	<property name="initialPoolSize" value="${c3p0.initialPoolSize}"/>  
</bean>

3)配置SessionFactory和事务管理器
applicationContext.xml

<bean id="sessionFactory"
	class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
	<property name="dataSource" ref="dataSource" />
	<property name="packagesToScan">
		<list>
			<value>org.yingzhuo.salary.domain</value>
		</list>
	</property>
	<property name="mappingResources">
		<list></list>
	</property>
	<property name="hibernateProperties">
		<props>
			<prop key="hibernate.dialect">${hibernate.dialect}</prop>
			<prop key="hibernate.show_sql">true</prop>
			<prop key="hibernate.format_sql">true</prop>
			<prop key="hibernate.hbm2ddl.auto">update</prop>
		</props>
	</property>
</bean>

<bean id="transactionManager"
	class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	<property name="sessionFactory" ref="sessionFactory" />
</bean>

4)配置事务

<!--
<tx:advice id="txAdvice">
	<tx:attributes>
		<tx:method name="find*" read-only="true"/>
		<tx:method name="*" propagation="REQUIRED"/>
	</tx:attributes>
</tx:advice>

<aop:config>
	<aop:pointcut expression="execution(* *..dao.impl..*(..))" id="dao-pc"/>
	<aop:pointcut expression="execution(* *..service.impl..*(..))" id="service-pc"/>
	<aop:advisor advice-ref="txAdvice" pointcut-ref="dao-pc"/>
	<aop:advisor advice-ref="txAdvice" pointcut-ref="service-pc"/>
</aop:config>
-->

<tx:annotation-driven />

<aop:aspectj-autoproxy />

6)异常转换 hibernate体系结构异常 -> spring体系结构异常

<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

※要转换的组件上要加入@Repository标注

7)数据库信息
database.properties

#====================================================================================
# jdbc infomation
#   jdbc.dirverClass              : 驱动类名
#   jdbc.url                      : 数据库统一资源描述符
#   jdbc.username                 : 数据库登录用户名

# c3p0 setting
#   c3p0.minPoolSize              : 连接池最小保存的连接数量
#   c3p0.maxPoolSize              : 连接池最大保存的连接数量
#   c3p0.initialPoolSize          : 连接池被创建时保存的连接数量
#   c3p0.maxIdleTime              : 连接的最大空闲时间，超时不被使用则丢弃
#   c3p0.acquireIncrement         : 当连接耗尽时每次申请的连接数量
#   c3p0.idleConnectionTestPeriod : 每间隔一定秒数秒检查所有连接池中的空闲连接
#   c3p0.acquireRetryAttempts     : 定义在从数据库获取新连接失败后重复尝试的次数
#====================================================================================
c3p0.minPoolSize=5
c3p0.maxPoolSize=30
c3p0.initialPoolSize=10
#c3p0.maxIdleTime=60
#c3p0.acquireIncrement=3
#c3p0.idleConnectionTestPeriod=60
#c3p0.acquireRetryAttempts=30
#c3p0.breakAfterAcquireFailure=true
#====================================================================================
# hibernate setting
#   hibernate.dialect             : 方言

hibernate.dialect=org.hibernate.dialect.MySQLDialect
