NHibernate, an entity corresponding to a hbm.xml, just at the beginning, I think the entity is written well,Hbm.xml write well, the database table generated well, then the end of the matter is simple, the rest is just write logic code, but , let me not think, after the database table is generated, and then in the process of writing logic code, about hbm.xml and entity reported errors, let me really angry, disgusting, now I encountered some errors to share out, hoping to bring your work alert and convenient.

Error Four:

Cause: double-check hbm.xml and entities to see if hbm.xml corresponds to the field in the entity, and you may have less than one Hbm.xml attribute in your entity.

Error Five:
