Spring提供的Hibernate申明式事務管理有兩種辦法
a) 配合使用org.springframework.transaction.interceptor.TransactionInterceptor和org.springframework.orm.hibernate.HibernateTransactionManager，下面是spring reference的例子
| 代碼: |
<beans>
...
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="mySessionFactory"/>
</property>
</bean>
<bean id="myTransactionInterceptor"
class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager">
<ref bean="myTransactionManager"/>
</property>
<property name="transactionAttributeSource">
<value>
product.ProductService.increasePrice*=PROPAGATION_REQUIRED
product.ProductService.someOtherBusinessMethod=PROPAGATION_MANDATORY
</value>
</property>
</bean>
<bean id="myProductServiceTarget" class="product.ProductServiceImpl">
<property name="productDao">
<ref bean="myProductDao"/>
</property>
</bean>
<bean id="myProductService" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces">
<value>product.ProductService</value>
</property>
<property name="target">
<ref local="myProductServiceTarget<"/>
</property>
<property name="interceptorNames">
<list>
<value>myTransactionInterceptor</value>
</list>
</property>
</bean>
</beans> |
HibernateInterceptor和事務無關，它的用途在javadocs中描述如下：
| 引用: |
This interceptor binds a new Hibernate Session to the thread before a method
call, closing and removing it afterwards in case of any method outcome.
If there already was a pre-bound Session (e.g. from HibernateTransactionManager,
or from a surrounding Hibernate-intercepted method), the interceptor simply
takes part in it. |
b)使用TransactionProxyFactoryBean，下面是Spring Reference中的例子
| 代碼: |
<beans>
...
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="mySessionFactory"/>
</property>
</bean>
<bean id="myProductServiceTarget" class="product.ProductServiceImpl">
<property name="productDao">
<ref bean="myProductDao"/>
</property>
</bean>
<bean id="myProductService"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="myTransactionManager"/>
</property>
<property name="target">
<ref bean="myProductServiceTarget"/>
</property>
<property name="transactionAttributes">
<props>
<prop key="increasePrice*">PROPAGATION_REQUIRED</prop>
<prop key="someOtherBusinessMethod">PROPAGATION_MANDATORY</prop>
</props>
</property>
</bean>
</beans>
|
在沒有其他AOP interceptor情況下，使用TransactionProxyFactoryBean是比較方便的。
事務劃分一般是的業務層，而不是在DAO一層。
2.代理工廠返回的是接口AddressDao的應用，通過接口最終調用target的方法。
3.TransactionDefinition定義了所有的事務屬性
