您可以使用 NHibernate映射生成器。

Is there a Class Map generator for Fluent NHibernate? I need something like db2hbm but I want it to generate Fluent Class Maps instead of xml mappings.

I am aware of AutoMapping for Fluent but that is not what I want. I want to be able to generate Class Map files from tables in database and push them to my src repository.

You can do this with NHibernate Mapping Generator.
