Our current database (MySQL) already has Indexes for its foreign keys since these use InnoDB, which (afaik) automatically generates IndexTables for foreign keys. Hibernate wasnt used to create these tables. So my question is: Is MySQL using Indexes for their foreign keys automatically, when I use Hibernate to fetch Data from its tables? Or do I have to configure Hibernate to use these Indexes?
Thank you,

Yes, the query optimizer decides to use or not to use an index. Use EXPLAIN on your SELECT statements to see what it uses. There is no difference in a query created by Hibernate or a hardcoded query.
