框架搭建（九）spring的AOP事物

 

1.配置核心事物管理器

<!-- 核心事物配置 AOP -->
	<bean name="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager" >
		<property name="sessionFactory" ref="sessionFactory" ></property>
	</bean>

2.在applicationContext.xml中配置AOP事物

（1）配置通知

 

<tx:advice id="txAdvice"
		transaction-manager="transactionManager"
		<tx:attributes>
			<tx:method name="save*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="persist*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="update*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="modify*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="delete*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="remove*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="false" />
			<tx:method name="get*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="true" />
			<tx:method name="find*" isolation="REPEATABLE_READ"
				propagation="REQUIRED" read-only="true" />
		</tx:attributes>
</tx:advice> 

（2）配置將通知織入目標

<aop:config>
<!--配置切點-->
<aop:pointcut expression="execution(* service.impl.*ServiceImpl.*(..))" id="txPc" />
<!--配置切面-->
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPc" />
</aop:config>

三.註解配置AOP事物

四.service類中使用註解

@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=true)
public class UserServiceImpl implements UserService{

在方法中定義，則只指定當前方法

@Override
@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=false)	
	public void saveUser(User u) {
		ud.save(u);
 }
