JPA Kriteri sorgusu Path.get left join bu mümkün

Question

JPA kriterleri ile ilgili bir sorum var.

İşte

CriteriaBuilder criteriaBuilder = getEm().getCriteriaBuilder(); 
CriteriaQuery<InventoryItemSumReport> query = criteriaBuilder.createQuery(InventoryItemSumReport.class); 
Root<InventoryItemDetail> from = query.from(InventoryItemDetail.class);  

Join<InventoryItemDetail, InventoryItem> joinItem = from.join(InventoryItemDetail_.inventoryItem); 

Predicate where = criteriaBuilder.lessThanOrEqualTo(from.get(InventoryItemDetail_.effectiveDate), date); 

query.multiselect(joinItem.get(InventoryItem_.product),joinItem.get(InventoryItem_.facility),joinItem.get(InventoryItem_.customer)); 
query.groupBy(joinItem.get(InventoryItem_.product),joinItem.get(InventoryItem_.facility),joinItem.get(InventoryItem_.customer)); 
query.where(where); 

TypedQuery<InventoryItemSumReport> createQuery = getEm().createQuery(query);  
List<InventoryItemSumReport> resultList = createQuery.getResultList();

benim JPA kriterleri sorgusudur

select 
     inventoryi1_.PRODUCT_ID as col_0_0_, 
     inventoryi1_.FACILITY_ID as col_1_0_, 
     inventoryi1_.CUSTOMER_ID as col_2_0_ 
    from 
     INVENTORY_ITEM_DETAIL inventoryi0_ 
    inner join 
     INVENTORY_ITEM inventoryi1_ 
      on inventoryi0_.INVENTORY_ITEM_ID=inventoryi1_.ID 
    inner join 
     PRODUCT product2_ 
      on inventoryi1_.PRODUCT_ID=product2_.ID 
    inner join 
     FACILITY facility3_ 
      on inventoryi1_.FACILITY_ID=facility3_.ID 
    inner join 
     CUSTOMER customer4_ 
      on inventoryi1_.CUSTOMER_ID=customer4_.ID 
    where 
     inventoryi0_.EFFECTIVE_DATE<= ? 
    group by 
     inventoryi1_.PRODUCT_ID , 
     inventoryi1_.FACILITY_ID , 
     inventoryi1_.CUSTOMER_ID 

Ama aşağıdaki sorguyu istiyorum:

select 
     inventoryi1_.PRODUCT_ID as col_0_0_, 
     inventoryi1_.FACILITY_ID as col_1_0_, 
     inventoryi1_.CUSTOMER_ID as col_2_0_ 
    from 
     INVENTORY_ITEM_DETAIL inventoryi0_ 
    inner join 
     INVENTORY_ITEM inventoryi1_ 
      on inventoryi0_.INVENTORY_ITEM_ID=inventoryi1_.ID 
    inner join 
     PRODUCT product2_ 
      on inventoryi1_.PRODUCT_ID=product2_.ID 
    inner join 
     FACILITY facility3_ 
      on inventoryi1_.FACILITY_ID=facility3_.ID 
    left join 
     CUSTOMER customer4_ 
      on inventoryi1_.CUSTOMER_ID=customer4_.ID 
    where 
     inventoryi0_.EFFECTIVE_DATE<= ? 
    group by 
     inventoryi1_.PRODUCT_ID , 
     inventoryi1_.FACILITY_ID , 
     inventoryi1_.CUSTOMER_ID 

ile

da sonuç almak için MÜŞTERİ üye ol Customers'un null olduğu yerler.
Customer, Product, Facility, hepsi girilir, InventoryItemSumReport ise Değer nesnesi veya DTO'dur. Çalışır şöyle

public class InventoryItemSumReport implements Serializable { 

    private static final long serialVersionUID = 1L; 

    private Product product; 
    private Facility facility; 
    private Customer customer; 

    public InventoryItemSumReport(Product product, Facility facility, Customer customer) { 
     super(); 
     this.product = product; 
     this.facility = facility; 
     this.customer = customer; 
    } 
}

buldum:

CriteriaBuilder criteriaBuilder = getEm().getCriteriaBuilder(); 
CriteriaQuery<InventoryItemSumReport> query = criteriaBuilder.createQuery(InventoryItemSumReport.class); 
Root<InventoryItemDetail> from = query.from(InventoryItemDetail.class);  

Join<InventoryItemDetail, InventoryItem> joinItem = from.join(InventoryItemDetail_.inventoryItem); 

Predicate where = criteriaBuilder.lessThanOrEqualTo(from.get(InventoryItemDetail_.effectiveDate), date); 

Join<InventoryItem, Customer> joinCustomer = joinItem.join(InventoryItem_.customer, JoinType.LEFT); 
query.multiselect(joinItem.get(InventoryItem_.product),joinItem.get(InventoryItem_.facility),joinItem.get(InventoryItem_.customer)); 
query.groupBy(joinItem.get(InventoryItem_.product),joinItem.get(InventoryItem_.facility),joinCustomer); 
query.where(where); 

TypedQuery<InventoryItemSumReport> createQuery = getEm().createQuery(query);  
List<InventoryItemSumReport> resultList = createQuery.getResultList();
