sping中注解事务的应用

1.spring配置文件中配置

	<aop:config>
		<aop:pointcut id="appService" expression="execution(* com.hhr.service.*Service*.*(..))" />
		<aop:advisor advice-ref="txAdvice" pointcut-ref="appService" />
	</aop:config>

	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="select*" read-only="true" />
			<tx:method name="find*" read-only="true" />
			<tx:method name="get*" read-only="true" />
			<tx:method name="*" />
		</tx:attributes>
	</tx:advice>

	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
	<tx:annotation-driven transaction-manager="transactionManager" />

2.调用

@Transactional(rollbackFor=Exception.class)
public void test(){
     update(obj)
      throw new Exception();
}

　其中 1)test方法中不能加try catch语句

　　　2)数据库表为innodb
