Question

我有一个关于Hibernate Search映射和使用抽象基类的问题。我收到以下错误

Caused by: org.hibernate.search.SearchException: Found invalid @IndexedEmbedded->paths configured on class nl.project.model.social.AbstractGroup, member language: language.id

基于以下映射配置

@Entity
@Table
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "DTYPE", discriminatorType= DiscriminatorType.STRING, length = 3)
@Indexed
public abstract class AbstractGroup implements Serializable, IEntity, IPhoto{

    protected Language language;

    @ManyToOne(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
    @JoinColumn(name="FK_LanguageId")
    @Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE,region=CacheRegion.NEVERCHANGE)
    @NotNull
    @IndexedEmbedded(includePaths={"id"})
    public Language getLanguage() {
        return language;
    }
}

@Entity
@DiscriminatorValue(value = "GRP")
@Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE,region=CacheRegion.GROUP)
public class Group extends AbstractGroup{

@Entity
@DiscriminatorValue(value = "PGE")
@Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE,region=CacheRegion.GROUP)
public class Page extends AbstractGroup{

我已经尝试将@Indexed放在子类上，但这会产生相同的错误。

Answer 1

@Indexed 注释应该确实在子类上。但是，我不确定这应该与te鉴别器列有什么关系。 JPA和搜索注释应该是正交的。真的有两件事。顺便问一下，你的 Language 实体是怎样的？另请参阅https://forum.hibernate.org/viewtopic.php?f=9&t=993097&hilit=abstract+base+class

使用includePaths映射抽象类
