Spring data method name for enum

Question

Is there any way to put enum value in method name with Spring Data? It can be done with @Query annotaion with something like this:

  @Query("select t from Ticket as t where t.status != desk.enums.TicketStatus.CLOSED")
  List<Ticket> findActiveTickets();

where status is the enum. But how can it be done with only using method names? Using something like List<Ticket> findByStatusIsNotClosed(); will cause No property isNotClosed found for type TicketStatus.

So how can it be done without using @Query?

Answer 1

If you're using Java 8, you can use the default keyword in the interface to delegate to a more generic method.

default List<Ticket> findActiveTickets() {
    return findByTicketStatusNotIn(ImmutableList.of(TicketStatus.CLOSED));
}

List<Ticket> findByTicketStatusNotIn(List<TicketStatus> status);
