方法拦截器：MethodInterceptor
MethodInterceptor --> org.springframework.aop.support.RegexpMethodPointcutAdvisor
ThrowsAdvice --> org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator

实现MethodInterceptor接口，在调用目标对象的方法时，就可以实现在调用方法之前、调用方法过程中、调用方法之后对其进行控制。
MethodInterceptor接口可以实现MethodBeforeAdvice接口、AfterReturningAdvice接口、ThrowsAdvice接口这三个接口能够所能够实现的功能，但是应该谨慎使用MethodInterceptor接口，很可能因为一时的疏忽忘记最重要的MethodInvocation而造成对目标对象方法调用失效，或者不能达到预期的设想。
