Querydsl @QueryInit funktioniert nicht

Question

Ich arbeite an einem Projekt, das ich kürzlich übernommen habe und versuche, Querydsl zu verwenden.

Ich habe einen Eintrag Klasse:

@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; 
    } 

... 

} 

und eine externe ID Klasse:

@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; 
    } 

} 

Ich habe eine ListingPredicates Klasse:

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)); 
    } 
} 

Wenn ich Auflistung zuzugreifen versuchen. masterId.provider in ListingPredicates.byMasterExternalIdAndProviderId(), Provider ist null, trotz der Tatsache, dass ichverwendet habe.

Wenn ich die Schaffung der Querydsl „Q“ Klassen debuggen, es gibt keine init Pfade für die masterId.

Kann mir bitte jemand erklären, warum meine @QueryInit nicht funktioniert?

Die Querydsl JPA-Annotation-Prozessor auf einem Klassenbasis entscheidet, ob Felder, Accessoren oder beide werden bei der Inspektion berücksichtigt, basierend darauf, wo relevante Anmerkungen verwendet werden. In dieser Phase werden nur JPA-Anmerkungen berücksichtigt.

Da Ihre JPA-Annotationen in den Gettern definiert sind, muss die QueryInit-Annotation ebenfalls dort eingefügt werden.
