  • Constructor Details

    • InMemoryJpaRepository

      public InMemoryJpaRepository()
      Creates a new InMemoryJpaRepository with no primary key generator. If an entity with a null primary key is saved, an exception is thrown.

    • InMemoryJpaRepository

      public InMemoryJpaRepository(PrimaryKeyGenerator<ID> primaryKeyGenerator)
      Creates a new InMemoryJpaRepository with the provided primary key generator. If an entity with a null primary key is saved, the generator is used to create a new primary key that is stored in the entity before saving.
      Parameters:
      primaryKeyGenerator - the primary key generator to use
