See if field is mapped

Is it possible to detect if a certain field of a given class has been mapped?

E.G.

I have the object;

MyObject {
   private MyOtherObject other
}

And in the mapping file;

<many-to-one name="other" class="com.mypackage.MyOtherObject" lazy="false" />

Now is it possible to detect in java, if other has been mapped? I know I can create a static class containing mapped fields etc. But I'd rather detect it on the fly. 开发者_开发百科Is that possible?

If you just want to see if the MyOtherObject is mapped, you can try to get the ClassMetadata from the SessionFactory for that class. If it's null, it's not mapped:

s.getSessionFactory().getClassMetadata(Bar.class);

use annotations instead of xml and get annotations on the fly using reflection.
