I was working on small POC, wanted to use 2 generator values in hbm.xml files using Hibernate 5.2.1+ Spring 4.3.1.

<class name="hibernate.test.Employee" table="emptest2">
<id name="uid">
<generator class="uuid"/>
</id>

<property name="name" />
</class>
</hibernate-mapping>

I want to make it generic for different databases, for that I have to maintain 2 different hbm.xml files for different dbs. May be I need to pass Custom generator value like uuid2, guid for connectivity with 2 databases but seems not possible or don't have any idea on this or Needed to pass a classname which can check the dialect or something.

When I see the code for DefaultIdentifierGeneratorFactory, here it registers generator (register( "uuid2", UUIDGenerator.class );) and maps to their relevant class file. I can't see any customized value or anything.

Also, I see one comment here with this:

*_register( "guid", GUIDGenerator.class );
// can be done with UUIDGenerator + strategy
_*

which I was unable to understand that how can I make a GUIDGenerator from UUIDGenerator+strategy. Please let me know the solution.
