Delete by query doesn't seems to work as expected

[cambierr]

Here is a sample repository:

@Repository
public interface UserRoleRepository extends ReactiveCrudRepository<UserRole, UUID> {
    @Query("delete from account.User_Role where user_id = $1")
    Mono<Void> deleteAllByUserId(UUID userId);
}

This produces the error org.springframework.data.mapping.MappingException: Couldn't find PersistentEntity for type class java.lang.Void! and I'm not sure to know how to make this work and wasn't able to find anything relevant in the documentation & issues.

Any help on this ? Thank you guys !

That’s a bug. Thanks for report.

I investigated the issue and found that Spring Framework does not consider Void.class (as in Mono<Void>) a primitive. When Spring Framework is able to fix the issue with spring-projects/spring-framework#23572, we're basically left with just adding a test.

The fix would be trivial on our side, otherwise.

Fixed via Spring Framework.
