Jaybird（CHAR（16）文字セットオクテット）

私は輸入java.util.UUIDとしてJPAのためのAttributeConverterが定義されているドメインJaybird（CHAR（16）文字セットオクテット）

CREATE DOMAIN OCTET16 AS CHAR(16) CHARACTER SET OCTETS;

によって定義されたUUID IDフィールドに問題があります。それは

私は問題を仮定しないバイナリ表現が、36文字のテキスト形式を変換しようとして

@Id 
@Convert(converter = UUIDAttributeConverter.class) 
private UUID id;

が、JPA（EclipseLinkは+ Eclipseのジェミニ）として

import javax.persistence.AttributeConverter; 
import javax.persistence.Converter; 

import com.ekser.nakkash.icdv.tools.UUIDTools; 

@Converter 
public class UUIDAttributeConverter implements AttributeConverter<UUID, byte[]> { 
    @Override 
    public byte[] convertToDatabaseColumn(UUID arg0) { 
     return UUIDTools.asBytes((UUID) arg0); 
    } 
    @Override 
    public UUID convertToEntityAttribute(byte[] arg0) { 
     return UUIDTools.asUUID((byte[])arg0); 
    } 
}

と定義されたJPAのフィールドは、エラーになりますjaybirdがCHAR（16）としてフィールドの型を与えていることです（ResultSetMetaDataでチェックしました）。 octetsAsBytesがあり、jbdcのURLと同じように使用しています。

jdbc:firebirdsql:localhost:D:/aktarma-12-13/VERI.FDB?octetsAsBytes=true

結果はありません。

私のセットアップは、だから私はBINARY問題が消えますようにResultSetMetaDataは私のフィールドの型を与えるときだと思う

Java 1.8 
Efxclipse 2.4.0 RCP 
Firebird 2.5.6 
Jaybird 2.2.12 JDK_1.8 
HikariCP 2.4.1 
EclipseLink 2.6.4 
Eclipse Gemini 1.2.0.M1

かなり複雑です。しかしどうですか？助言がありますか。

idsをchar（32）またはchar（36）として保持したくないだけです。

編集：Jaybird 3.beta-2に切り替えた後、一つは第三のラインinvalid stream header: F1505533明らかに見ることができます。これは部分的にASCIIデコードされたid（char（16）文字集合オクテット）です。この値を生のバイトとして受け入れ、JPAにUUIDAttributeConverterクラスを渡す方法を教えてください。

書き込み時にドライバがバイト[]を処理できるかどうかは、読み込み時のみ問題ですか？その場合は、ドライバから返された文字列をコンバーターで処理してください。 – Chris

[Jaybird 3-beta-2]（https://github.com/FirebirdSQL/jaybird/releases/tag/v3.0.0-beta-2）で試してみてください。 'char（16）character set octets '型は' binary'型として常に、[JDBC（VAR）BINARYとして扱われる文字セットOCTETS]（https://www.firebirdsql.org/file/documentation/drivers_documentation/java/3.0.0-beta-2/release_notesを参照してください。 html＃character-set-octets-as-jdbc-varbinary）を使用します。残念ながら、Jaybird 2.2の 'octetsAsBytes'は一貫して適用されません（' ResultSetMetaData'の場合には適用されますが、例えば 'getObject'が結果セットで使用されていると動作しません）。 –

ご参考まで：ご質問に実際のエラーを含めると便利です。 –

私はこれをテストするためのEclipseLink 2.6.4を使用して簡単なプロジェクトを行っている、とJaybird 2.2.12（octetsAsBytes=trueを設定することが必須である）とJaybird 3.0.0-β-2との両方が、それは動作します：
