通过配置织入@Aspectj切面

虽然可以通过编程的方式织入切面,但是一般情况下,我们还是使用spring的配置自动完成创建代理织入切面的工作。

通过aop命名空间的声明自动为spring容器中那些配置@aspectJ切面的bean创建代理,织入切面。当然,spring

在内部依旧采用AnnotationAwareAspectJAutoProxyCreator进行自动代理的创建工作,但具体实现的细节已经被<aop:aspectj-autoproxy />隐藏起来了

<aop:aspectj-autoproxy />有一个proxy-target-class属性,默认为false,表示使用jdk动态代理织入增强,当配为<aop:aspectj-autoproxy poxy-target-class="true"/>时,表示使用CGLib动态代理技术织入增强。不过即使proxy-target-class设置为false,如果目标类没有声明接口,则spring将自动使用CGLib动态代理。

去掉 @serivce,因为这路径还没有把com.zx.aop.AirthmeticDaoImp包含在内,就开始执行了
或者把<aop:aspectj-autoproxy/> 修改成<aop:aspectj-autoproxy proxy-target-class="true"/>
