hibernate search 嵌套索引

官方文档


最基本配置

<property name="hibernate.search.default.directory_provider" 
   value="org.hibernate.search.store.FSDirectoryProvider"/> 

<property name="hibernate.search.default.indexBase" value="/var/lucene/indexes"/> 

一个一对多关联的例子
配置前

package example;
...
@Entity
public class Book {

  @Id
  @GeneratedValue
  private Integer id; 

  private String title;  

  private String subtitle; 

  @ManyToMany 
  private Set<Author> authors = new HashSet<Author>();

  private Date publicationDate;
  
  public Book() {
  } 
  
  // standard getters/setters follow here
  ...
} 

package example;
...
@Entity
public class Author {

  @Id
  @GeneratedValue
  private Integer id;

  private String name;

  public Author() {
  } 
 
  // standard getters/setters follow here
  ...
}

配置后

package example;
...
@Entity
@Indexed
public class Book {

  @Id
  @GeneratedValue
  @DocumentId
  private Integer id;
  
  @Field(index=Index.TOKENIZED, store=Store.NO)
  private String title;
  
  @Field(index=Index.TOKENIZED, store=Store.NO)
  private String subtitle; 

  @IndexedEmbedded
  @ManyToMany 
  private Set<Author> authors = new HashSet<Author>();

  @Field(index = Index.UN_TOKENIZED, store = Store.YES)
  @DateBridge(resolution = Resolution.DAY)
  private Date publicationDate;
  
  public Book() {
  } 
  
  // standard getters/setters follow here
  ... 
}

package example;
...
@Entity
public class Author {

  @Id
  @GeneratedValue
  private Integer id;

  @Field(index=Index.TOKENIZED, store=Store.NO)
  private String name;

  public Author() {
  } 
 
  // standard getters/setters follow here
  ...
}
