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!
