> The query interface allows for easy usage of JPA queries. Basically you annotate an interface as follows:
> {code}
> public interface QueryInterface {
> 		@QueryMethod("person.query.all")
> 		List<Person> getAll();
> 		@QueryMethod("person.select.by.name")
> 		Person getPersonByName(@QueryParam("name") String name);
> 		@QueryMethod(value = "person.select.by.name", nullable = true)
> 		Person findPersonByName(@QueryParam("name") String name);
> 		@QueryMethod("person.query.all")
> 		Query getAllQuery();
> 		
> 		@QueryMethod(query = "SELECT COUNT(*) FROM Person")
> 		Long countAll();
> 	}
> {code}
> Using some inject QueryInterfaceFactory you can get a proxy on this interface that will interpret the annotations towards JPA queries. See attached patch for a basic implementation.
