Spring AOP代理Controller层

基础学的不扎实,面试时被虐惨了..回来狂抓基础了..
看到spring Aop这块想优化下以前项目的代码,网上看了半天,各种案例,试了又试,没什么效果,说扫描包第一次扫描后,第二次就不会扫描了,所以Aop不会起效..(熟悉Jvm会懂的..)
网上寻它千百度,重要在google搜素时看到个提问,试试了下有用!(在这里不得不吐糟下百度了..)

@Component
@Aspect

    }

    @Before(value = "cutController()")
    public void doAccessCheck() {
        System.out.println("前置通知");
    }

    @After(value = "cutController()")
    public void after() {
        System.out.println("最终通知");

        Object result = point.proceed();
