查询单向many2one索引

Question

我试图将Hibernate搜索索引设置为以下关系：

DocVersion *<-> Document2 -> DocType

@Indexed
@Entity
public class Document2 implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "doc_uuid")
    private long id;

    @IndexedEmbedded
    @ManyToOne(cascade = CascadeType.MERGE, fetch = FetchType.LAZY)
    @JoinColumn(name = "documentType")
    private DocType docType;
}



@Indexed
@Entity
public class DocType implements  Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "doctype_id")
    private long id;

    @Field
    @Column(name = "documentType")
    private String documentType;
}

所以它是来自Document2类的统一Document2关系，因为DocType只是一个可编码的。

但是，我需要根据cdt的属性(如document2.docType.documentType )查询索引，这给了我：

WARNING: org.hibernate.search.exception.SearchException: Unable to find field document2.docType.documentType in com.nws.vedica.model.entity.DocVersion

我遗漏了什么？

因此，我错过了@ContainedIn，这需要在@IndexedEmbedded的另一边。在Document2对我来说

    @ContainedIn
    @OneToMany(mappedBy = "document2", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @org.hibernate.annotations.Cache(
            usage = CacheConcurrencyStrategy.READ_WRITE
    )
    private Set<DocVersion> docVersions;

而在DocType中，作为一个“叶子”，根本不需要链接到Document2。

希望这对某人有帮助
