Spring CrudRepository findByInventoryIds(List inventoryIdList) - equivalent to IN clause

Question

In Spring CrudRepository, do we have support for \"IN clause\" for a field? ie something similar to the following?

 findByInventoryIds(List inve         


        

Answer 1

Yes, that is supported.

Check the documentation provided here for the supported keywords inside method names.

You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:

List findByIdIn(List ids);

I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:

The Entity

@Entity
public class Inventory implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long id;

  // other fields
  // getters/setters

}

The Repository

@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository {

  List findByIdIn(List ids);

}
