@annotation
使用@annotation指定注解标注的方法将会被环绕(与@within的相似)
@annotation(annotation-type)
@Around("@annotation(com.business.annotation.FruitAspect)")
bean（）
允许我们在切点表达式中使用bean的id来标识bean
使用beandi或bean名称作为参数来限制切点只能匹配特定的bean
execution（。。。）and bean('bean名称')
@DeclareParents
为指定的目标类引入新的属性和方法
@DeclareParents(value = "TargetType", defaultImpl = WeaverType.class)<br>private WeaverInterface attribute;
perthis和pertarget
@Aspect("perthis(this(com.spring.service.Apple))")
