ByteBuddy - 重新定义给定包中的所有类

Question

I have a package called com.company.beans . What I would like to do, is to upperCase and trim all fields of type String for each class from this package. I've seen this post Using Bytebuddy to intercept setter which seems to be a good solution to what I want to do.

Here is the piece of code I'm trying to redefine:

 bb.subclass(BaseUser.class) // how to specify my package ? 
            .method(isDeclaredBy(BaseUser.class).and(isSetter()))
            .intercept(MethodDelegation.to(interceptor))
            .make()
            .load(BaseUser.class.getClassLoader(), ClassLoadingStrategy.Default.WRAPPER);

How do I specify all classes from a given package? Also, I'm using spring boot. Where should I put my ByteBuddy configuration?

Thanks.

There are libraries to scan the class path such as Class Graph which you can use for this purpose. There's nothing in Byte Buddy for it since this is considered a different domain.
