1.配置核心事物管理器

<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）配置将通知织入目标

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

三.注解配置AOP事物

四.service类中使用注解

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

在方法中定义，则只指定当前方法

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