I finally got around to adding a dedicated BeanCopier class to CGLIB. The API looks something like:
BeanCopier copier = BeanCopier.create(bean1.getClass(), bean2.getClass()); copier.copy(bean1, bean2);
The copiers are cached, but if you can reuse the very same instance you get much faster times, so I've benchmarked both ways. This is for 100000 iterations on JDK 1.4.2_01 (Linux).
CGLIB? Reuse copier? Duration ------ ------------- -------- No N/A 4,110 ms <-- PU.copyProperties(bean,bean) Yes No 87 ms Yes Yes 5 ms
The results were better than I expected :-) The generated code is very simple which I think lets HotSpot really go to town.
