保留 CGLIB 代理上的注释?

2022-01-13 00:00:00 annotations java cglib

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!

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

Cheers! Nirav

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.

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 {
}
