@Target(ElementType.TYPE)//ElementType.TYPE表示可以用在类上，ElementType.METHOD表示可以用在方法上
@Retention(RetentionPolicy.RUNTIME)//RetentionPolicy.RUNTIME运行事保留RetentionPolicy.CLASS编译时保留
@Documented//会被 javadoc 之类的工具处理
@Inherited//表示可以被继承
public @interface ClassRateLimit {
 
}

@Aspect
@Component
public class ClassAnnotationAspect {

    @Pointcut("@within(classRateLimit)")
    public void annotationPointcut(ClassRateLimit classRateLimit) {
    }


    @Before("@within(classRateLimit)")
    public void doBefore(JoinPoint joinPoint, ClassRateLimit classRateLimit) {
    	//classRateLimit 通过这个对象获取注解中的属性
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();//通过这个对象取得本次请求的方法信息
            
            Class[] clazz=joinPoint.getClass();//通过这个对象取得本次请求的类信息
             ServletRequestAttributes requestAttributes = (ServletRequestAttributes) //通过这个对象取得本次请求的request和response信息
             RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        HttpServletResponse response = requestAttributes.getResponse();
    }
}
