How to get Hibernate object relations dynamically?

Question

Hi,

I'm using Hibernate and I need to find a way of retrieving the relations for an object dynamically at run-time. I can't find this in the API.

Can anyone point me in the right direction please?

Thanks

Answer 1

What You look for is SessionFactory's getClassMetadata() method. It returns ClassMetadata object describing given entity.

Answer 2

My best recommendation is to use plain JDBC DatabaseMetaData

DatabaseMetaData.getCrossReference

DatabaseMetaData.getImportedKeys

DatabaseMetaData.getExportedKeys

Examples
