There's no equivalent. There have been loooooong discussions about this in JAX-RS 2.0 EG. But the introduction of interceptors made us drop this support in favor of compact API.

Admittedly, it's not a completely easy task. You need to buffer the entity, convert to string, and then set the buffered input as the new entity stream. See Jersey 2.0 logging filter, that you can use (or mimic it's impl.):
