Both Spring Data and DeltaSpike Data module support using QueryDSL to write custom queries. So instead as a replacement for either of them, you should think of it as a complementary tool that you can turn to when the "repository generators" don't feel that handy anymore. And you can think it as a more...
JPA 2 introduces a criteria API that you can use to build queries programmatically. By writing a criteria, you define the where clause of a query for a domain class. Taking another step back, these criteria can be regarded as a predicate over the entity that is described by the JPA criteria API constraints.
