当下面注掉时,需要把最上面的方法打开,这样才能调用
<!-- <bean id="logInterceptor" class="com.bjsxt.aop.LogInterceptor"></bean> --> <!-- <aop:config> --> <!-- <aop:aspect id="logAspect" ref="logInterceptor"> --> <!-- <aop:before method="before" --> <!-- pointcut="execution(public * com.bjsxt.service..*.add(..))" /> --> <!-- <aop:around method="aroundMethod" --> <!-- pointcut="execution(public * com.bjsxt.service..*.add(..))" /> --> <!-- <aop:after method="aroundMethod" --> <!-- pointcut="execution(public * com.bjsxt.service..*.add(..))" /> --> <!-- </aop:aspect> --> <!-- </aop:config> -->
总结:一种是在java 文件里,进行配置; 另一种是在xml 文件中进行配,都能实现相应的调用!
