1、TransactionProxyFactoryBean

        <!--
            注意这个属性, 详细意义请参考Spring文档中的CGLIB部分或者本章的 10.7.2参考资料部分, 必须为 true
            使用CGLIB才不用强制编写DAO接口

3、AOP和TX配置

        </property>
    </bean>
    <!-- 需要引入aop的命名空间 -->
    <aop:config>
        <!-- 切入点指明了在执行Service的所有方法时产生事务拦截操作 -->
        <aop:pointcut id="daoMethods"
            expression="execution(* com.angi.dao.service.TblUserService.*(..))" />
        <!-- 定义了将采用何种拦截操作，这里引用到 txAdvice -->

    </tx:advice>
</beans>
4、anotation

@Transactional
