Lucene没有遍历索引中的模型

以下是我的代码的基本概要:

@Entity
@Indexed
public class Document {

  @IndexedEmbedded
  @OneToMany(cascade = { PERSIST, MERGE }, mappedBy = "owner")
  private final Set<Issue> issues = new LinkedHashSet<Issue>();
}

@Entity
public class Issue {

  @ManyToOne
  @JoinColumn(name = "owner_id")
  @ContainedIn
  private final Document owner;

  @IndexedEmbedded
  @OneToOne(cascade = ALL, optional = false)
  @JoinColumn(name = "name_id")
  @ForeignKey(name = "FK_issue__name_id__text_element")
  private final TextElement name = new TextElement();
}

@Entity
public class TextElement {

  @OneToMany(cascade = { CascadeType.ALL })
  @JoinTable(
    name = "text_element_paragraph",
    joinColumns = { @JoinColumn(name = "text_element_id") },
    inverseJoinColumns = { @JoinColumn(name = "paragraph_id") },
    uniqueConstraints = { 
    @UniqueConstraint(
     name = "UX_text_element_paragraph__paragraph_id", 
     columnNames = "paragraph_id"        
    )
   }
  )
  @ForeignKey(
    name = "FK_text_element_paragraph__text_element_id__text_element",
    inverseName = "FK_text_element_paragraph__paragraph_id__paragraph"
  )
  @IndexedEmbedded
  private List<Paragraph> paragraphs = new LinkedList<Paragraph>();
}

@Entity
public class Paragraph {

  @Field(name = "data", analyze = Analyze.YES)
  @Column(name = "s_data", nullable = false)
  private String data;
}

我认为lucene会将段落中的数据编入索引,但是当我打开Luke时,它会显示&#34; issues.name.id&#34; (id来自一个Document扩展的类)。为什么不对数据编制索引?谢谢:))

我还应该注意,我刚从CRUD服务中的update方法中删除了一个手动索引器。之后一切都停止了,可能是我的配置吗?

2 个答案:

答案 0 :(得分:0)

通过在TextElement中添加以下内容,我能够进行搜索工作:

@ContainedIn
private Document owner 

答案 1 :(得分:-1)

我认为所有实体都必须注释为@Indexed,否则@IndexEmbedded将无法识别要编入索引的实体。

顺便说一下:深度遍历可能会导致重新索引出现问题。您需要使用@ContainedIn ...
