## 类 AspectMetadata

- java.lang.Object
- - org.springframework.aop.aspectj.annotation.AspectMetadata

- 所有已实现的接口:
    Serializable

      public class AspectMetadata
      extends Object
      implements Serializable

  Metadata for an AspectJ aspect class, with an additional Spring AOP pointcut for the per clause.

  Uses AspectJ 5 AJType reflection API, enabling us to work with different AspectJ instantiation models such as "singleton", "pertarget" and "perthis".
