次のデータモデルがあります。
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class AbstractRecord
implements Serializable
{
...
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
@Column(name = "id", nullable = false)
@DocumentId
private Integer id;
...
}
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@NamedQueries(...)
})
public abstract class AbstractEntryDetail
extends AbstractRecord
implements Serializable
{
...
}
@Indexed(index = "entryDetailIndex")
@Entity
@Table(name = "nacha_entry_detail")
@NamedQueries(...)
})
public class EntryDetail
extends AbstractEntryDetail
implements Serializable
{
...
@Field(index = Index.TOKENIZED, store = Store.NO)
@Column(name = "receiver_name", nullable = false)
private String receiverName;
...
}
@Indexed(index = "entryDetailCtxIndex")
@Entity
@Table(name = "nacha_entry_detail_ctx")
@NamedQueries(...)
public class EntryDetailCtx
extends AbstractEntryDetail
implements Serializable
{
...
@Field(index = Index.TOKENIZED, store = Store.NO)
@Column(name = "receiver_name", nullable = false)
private String receiverName;
...
}
ご覧のとおり、EntryDetailとEntryDetailCtxは同じプロパティ「Receivername」を共有しています。次のコードを介して「個人name1」と言う値を検索する際に問題があります。
@Stateless
@TransactionAttribute(TransactionAttributeType.MANDATORY)
@RolesAllowed({PermissionUtil.SEARCH_LIST,
PermissionUtil.LUCENE_INDEX
})
public class SearchFacade
{
...
@RolesAllowed(PermissionUtil.SEARCH_LIST)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public List<AbstractRecord> doSearch(String stringToFind)
{
List<AbstractRecord> result = null;
// Test Search for specific values of an Abstract Record
// Aim to return the number of retreived results
EntityManager em = emf.createEntityManager();
FullTextEntityManager fullTextEntityManager =
org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
String[] fields =
// Fields to be reviewed
new String[]
{ ....,"receiverName",....
};
//Create a multi-field Lucene query
StandardAnalyzer stdAnalyzer = new StandardAnalyzer(Version.LUCENE_30);
MultiFieldQueryParser parser =
new MultiFieldQueryParser(Version.LUCENE_30, fields, stdAnalyzer);
org.apache.lucene.search.Query query = null;
try
{
query = parser.parse(stringToFind);
}
catch (ParseException ex)
{
Logger.getLogger(SearchFacade.class.getName()).log(Level.SEVERE, null, ex);
}
long time1 = System.currentTimeMillis();
// Wrap Lucene query in a javax.persistence.Query
javax.persistence.Query persistenceQuery =
fullTextEntityManager.createFullTextQuery(query);
// Execute search
//HAVING PROBLEMS HERE
result = (List<AbstractRecord>) persistenceQuery.getResultList();
long time2 = System.currentTimeMillis();
Logger.getLogger(SearchFacade.class.getName())
.log(
Level.FINER, "Hibernate Search Execution time: {0}",
Long.toString(time2 - time1));
//em.getTransaction().commit();
em.close();
return result;
}
したがって、エンティティのインデックスを作成し、データベースで共有されている「Receivername」で検索を実行しようとした後、「Jhon」と言って、次の例外が得られます。

私は多くの冬眠検索フォーラムを読み、肯定的な結果なしにアクションブックでの冬眠検索を読みました。ありがとう
編集: ：問題は、EntryDetailとEntryDetailCtxの両方が同じIDを持つことができることであることがわかりました（両方とも異なる表にあるためです。） @documentID abstractrecordから継承される検索実行時に両方のテーブルで複製することができます。問題が発生します...今、私は追加の問題があり、それは次のとおりです。
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class AbstractRecord
implements Serializable
{
//~ Instance variables ---------------------------------------------------------------
/** SERIALID */ public static final String SERIALID = "hyzmfgSwl5hsDbxZIitNILMT2/eiPYJErJcqIMun3/PVy3SbbiQie4k9lLnL450BhwL8EnUMyc+wrhgZtUBTdG9/YUuJ+ni/FRAdRGzTy7UrQI7opbrYRYehDUwj3hg9";
/** id for this record. */
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
@Column(name = "id", nullable = false)
private Integer id;
/** line number for this record. */
@Field(index=Index.UN_TOKENIZED, store=Store.NO)
@Column(name = "record_number", nullable = false)
private Integer recordNumber;
/** record types for this record. */
@Field(index=Index.UN_TOKENIZED, store=Store.NO)
@Column(name = "record_type", nullable = false)
private Integer recordType;
/** Current status for this record. */
@Field(index=Index.UN_TOKENIZED, store=Store.NO)
@Column(name = "record_status", nullable = false)
@Enumerated(EnumType.ORDINAL)
private RecordStatus recordStatus;
/** unique table key for the file. */
@Field(index=Index.UN_TOKENIZED, store=Store.NO)
@Column(name = "unique_table_key", nullable = false)
private String uniqueTableKey;
...
}
検索のために私の新しい @DocumentIDになるには、UniqueTableKeyとRecordNumberが必要ですが、Hibernate Searchは1 DocumentIDのみを許可しますか？
