aop学习总结三----aop的相关概念

public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable {//环绕通知
PersonServiceBean bean = (PersonServiceBean) this.targetObject;
Object result = null;
if(bean.getUser()!=null){
//beforeadvice()-->前置通知
try {
result = method.invoke(targetObject, args);
// afteradvice() -->后置通知
} catch (RuntimeException e) {
//exceptionadvice()--> 例外通知
}finally{
//finallyadvice(); -->最终通知
}
}
return result;
}
