保留在CGLIB代理注解？ [英] Retain annotations on CGLIB proxies?

问题描述

想创建使用AOP框架，它使用CGLIB创建的代理对象的对象。
奇怪的是，强化的代理对象是没有任何注解previous类的了！

Am trying to create an object using an AOP framework which uses CGLIB to create proxy objects. Strangely enough, the "enhanced" proxy object is devoid of ANY annotations the previous class had!

谁能告诉我，我怎样才能使CGLIB保留在它创建？

Can anyone tell me how can I make CGLIB retain the annotations on the proxies it creates?

干杯！

推荐答案

CGLIB创建给定类的子类来生成代理。注释都没有在子类pserved除非注释定义明确指定$ P $。 <一href=\"http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/annotation/Inherited.html\">@Inherited注释用于此目的。

CGLIB creates subclasses of given classes to generate proxies. Annotations are not preserved in subclasses unless explicitly specified in annotation definition. @Inherited annotation is used for this purpose.

您可以在您定义的注释使用此批注，并让他们在子类中访问，如下：

You can use this annotation in the annotations you define, and make them reachable in subclasses, as following:

@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface MyAnnotation {
}
