Hi Pengfei,
I am a bit confused. You stated you turned the POJO mapping feature off.
Then Jackson JAX-RS provider won't be used and you can not expect anything
from it as the internal JAXB->JSON mapping is not leveraging the Jackson
features
described by Tatu. I think, and Tatu could confirm, if you switched the
POJO mapping
back on, and provided your own custom (Jackson) serialization implementation
for the class, that should work for you as requested.
