Hibernate Search无法使用@IdClass使用复合主键

问题描述

我在班级Intervento上配置了hibernate-search注释(4.1.1版本库).因此，我正在使用jpa，在我的情况下，我可以省略@DocumentId，但是我有一个复合主键...

...

我要....你能帮我吗?

解决方案

休眠搜索不处理与 @IdClass 一起使用的复合ID类.一种解决方法是使用 @EmbeddedId 并将 idintervento 和 linguaIdlingua 放入 InterventoPK 中.

似乎您在Hibernate Search论坛上也问了同样的问题- https://forum.hibernate.org/viewtopic.php?f=9&t=1024512

I've configured with hibernate-search annotation (4.1.1 version library) my class Intervento. So, I'm using jpa and in my case i can omit @DocumentId but I have a composite primary key...

@IdClass(it.domain.InterventoPK.class)
@Entity
@Indexed
@AnalyzerDef(name = "interventongram", tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
filters = {
     @TokenFilterDef(factory = LowerCaseFilterFactory.class),
     @TokenFilterDef(factory = StopFilterFactory.class, params = {
         @Parameter(name = "words", value = "lucene/dictionary/stopwords.txt"),
         @Parameter(name = "ignoreCase", value = "true"),
         @Parameter(name = "enablePositionIncrements", value = "true")
     }),
     @TokenFilterDef(factory = ItalianLightStemFilterFactory.class),
     @TokenFilterDef(factory = SynonymFilterFactory.class, params = {
         @Parameter(name = "synonyms", value = "lucene/dictionary/synonyms.txt"),
         @Parameter(name = "expand", value = "true")
     }),
     @TokenFilterDef(factory = SnowballPorterFilterFactory.class, params = {
            @Parameter(name = "language", value = "Italian")
     })
})



@Table(name = "intervento", catalog = "gestionale")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace = "Clinigo/it/domain", name = "Intervento")
@XmlRootElement(namespace = "Clinigo/it/domain")
public class Intervento implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     */

    @Column(name = "idintervento", nullable = false)
    @Basic(fetch = FetchType.EAGER)
    @Id
    @XmlElement
    Integer idintervento;
    /**
     */

    @Column(name = "lingua_idlingua", nullable = false)
    @Basic(fetch = FetchType.EAGER)
    @Id
    @XmlElement
    Integer linguaIdlingua;
    /**
     */
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "version", nullable = false)
    @Basic(fetch = FetchType.EAGER)
    @XmlElement
    Calendar version;

I'm getting....can you help me?

解决方案

Hibernate Search does not handle composite id classes used with @IdClass. A workaround would be to use @EmbeddedId and place idintervento and linguaIdlingua into InterventoPK.

Seems also that you asked the same question on the Hibernate Search forum - https://forum.hibernate.org/viewtopic.php?f=9&t=1024512

这篇关于Hibernate Search无法使用@IdClass使用复合主键的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
