Multiple SessionFactories, Multiple DataSources and Hibernate TransactionManager can accept only one Sessionfactory

Question

I have a @Transactional annotation in all my DAOs, but I can only define one TransactionManager that accepts only one SessionFactory. I have one SessionFactory for each client, one DataSource for each client and apparently I need to change the TransactionManager for each client. But how can I get the correct transaction manager for the client when I can only define one Spring bean name for one TransactionManager?
