How to create a copy of a class with javassist?

问题

With Javassist, how can I create an absolutely the same class as the one I have, but with a different name. I want to preserve all runtime annotations as well.

回答1:

ClassPool pool = ClassPool.getDefault();
CtClass cc = pool.get("OriginalName");
cc.setName("NewName");
cc.writeFile();

回答2:

Works fine for me like this:

javassist.ClassPool.getDefault()
  .getAndRename("com.example.Foo", "com.example.Bar")
  .toClass();
