Querydsl @QueryInit çalışmıyor

Question

Kısa bir süre önce devraldığım bir proje üzerinde çalışıyorum ve Querydsl kullanmaya dönüştürmeye çalışıyorum. I listesine erişmeyi denediğinde

public class ListingPredicates { 

    public static BooleanExpression byMasterExternalIdAndProviderId(
     final String externalId, final Long providerId) { 

     QEListing listing = QEListing.eListing; 

     return listing.masterId.externalId.equalsIgnoreCase(externalId).and(
      listing.masterId.provider.id.eq(providerId)); 
    } 
} 

:

@Entity 
public class EListing { 

... 

    private static final long serialVersionUID = 7729681308228522567L; 

    @QueryInit("provider") 
    private EExternalId masterId; 

    @OneToOne(fetch = FetchType.EAGER, 
      orphanRemoval = true, 
      cascade = CascadeType.ALL) 
    @JoinColumn(name = "master_ext_id") 
    @NotNull(message = EvalMessageCode.LISTING_MASTERID_NOTNULL) 
    @Valid 
    public EExternalId getMasterId() { 

     return masterId; 
    } 

    public void setMasterId(final EExternalId masterId) { 

     this.masterId = masterId; 
    } 

... 

} 

Ve Harici Kimlik sınıfı:

@Entity 
public class EExternalId implements Serializable { 

    public static final String FIELD_PROVIDER_PREFIX = "provder."; 

    private static final long serialVersionUID = -4577890108032056848L; 

    private String externalId; 

    private Long id; 

    private EDataProvider provider; 

    @Column(name = "external_id", 
      updatable = false) 
    @NotBlank(message = EvalMessageCode.EXTID_ID_NOTBLANK) 
    public String getExternalId() { 

     return externalId; 
    } 

    @Id 
    @GeneratedValue(generator = "external_id_seq") 
    @Column(name = "id") 
    public Long getId() { 

     return id; 
    } 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "provider_id", 
       nullable = false, 
       updatable = false) 
    @IndexedEmbedded(prefix = FIELD_PROVIDER_PREFIX) 
    @NotNull(message = EvalMessageCode.EXTID_PROVIDER_NOTNULL) 
    public EDataProvider getProvider() { 

     return provider; 
    } 

    public void setExternalId(final String externalId) { 

     this.externalId = externalId; 
    } 

    public void setId(final Long id) { 

     this.id = id; 
    } 

    public void setProvider(final EDataProvider provider) { 

     this.provider = provider; 
    } 

} 

Bir ListingPredicates sınıf var

Bir İlan dersim var. ListingPredicates.byMasterExternalIdAndProviderId() içinde masterId.provider,kullanmamıza rağmen sağlayıcısı null.

Querydsl "Q" sınıflarının oluşturulmasında hata ayıklanırsa, masterId için başlangıç ​​yolu yoktur.

Birisi neden @QueryInit neden çalışmıyor olduğunu açıklayabilir mi?

Querydsl JPA açıklama işlemci sınıf bazında karar verir

Answer 1

eğer alanları, erişimcileri İlgili ek açıklamaların kullanıldığı yerlerde, ya da her ikisi de denetimde dikkate alınır. Bu aşamada sadece JPA ek açıklamaları dikkate alınır.

JPA ek açıklamalarınız alıcılarda tanımlandığından, QueryInit ek açıklamalarının da buraya eklenmesi gerekir.
