Hibernate Entity dependant on column value

Is it possible with Hibernate to have a single table in the database, which stores multiple types of entities, differentiated开发者_如何学JAVA by the value of some column?

I've got an application that uses lists of data, the structure of all the data is the same - id, description, sequence. Currently I have one table per list, which means many tables that are all structurally the same.

What I want to do is to add one more piece of data to the list data - entity type, and then stuff it all in one table. The problem I've encountered so far is that now I can not use constructs like find("from " + EntityName.class) or loadAll(EntityName.class) - because that would load the lot.

Is there some way of configuring the entity to automatically add a where clause to ensure only the right type of data is returned per entity? (Ie, I don't want to have to add the where clause to each but of code that loads each entity)

Yes. What you're describing is the "table per class hierarchy" inheritance mapping strategy.
