Note that JPA uses a custom VO to receive jpql query results

           //new  A custom VO( The parameters in brackets need to implement the corresponding construction method )
@Query(value = "select new EquipmentStatusVO(eq.eqtExtId,es.eqtStatus,model.eqtType) from EquipmentStatusEntity es join EquipmentJunctionRelEntity rel " +
// Use entity Class to proceed join operation 
            "on str(es.eqtId) = rel.eqtId join Equipment eq on es.eqtId = eq.id join EquipmentModelEntity model on eq.eqtTypeId = model.modelId where rel.junctionId =:junctionId ")
    List<EquipmentStatusVO> getEquipmentStatusWithJunction(@Param("junctionId") String junctionId);
