Spring Data JPA: Check Exists Entity ID with @Query Annotation

I'm trying to make a simple JPQL using for check exist Entity Id.

My PlanDetail Entity:

Entity
@Table(name="T_PLAN_DETAIL")
public class PlanDetail extends AbstractProcessEntity {

@ManyToOne
@JoinColumn(name = "TERRITORY_ID")
private Territory territory;
...
}

I want to check it using Assert:

Assert.isTrue(planDetailRepository.existsByTerritory(territoryId), "This territory exist with ID = " + territoryId);

My PlanDetail Entity:

public interface PlanDetailRepository extends CrudRepository<PlanDetail, Long> {

@Query("SELECT COUNT(e)>0 FROM PlanDetail e WHERE e.terrritoryId=?1")
boolean existsByTerritory(Long territoryId);
}

Error Log:

Caused by: java.lang.IllegalArgumentException: org.hibernate.QueryException: could not resolve property: terrritoryId of: test.domain.model.plan.PlanDetail [SELECT COUNT(e)>0 FROM test.domain.model.plan.PlanDetail e WHERE e.terrritoryId=?1]

Any help is appreciated. Can you advise me any JPQL document.. Thanks.

Assuming your Territory entity has a field called "id".

Change your query to:

@Query("SELECT COUNT(e)>0 FROM PlanDetail e WHERE e.territory.id=?1")
