私は、SQL Server 2016、Spring Boot 1.5.8、Hibernate 5.2、およびSpring Data JPAをHikari 2.7で使用しています。サービスはデシベルと対話するよりも、私は、標準的な春の方法を使用していますvarbinaryからBLOBへの変換はサポートされていません

registerColumnType(Types.VARBINARY, "VARBINARY(MAX)");
//registerColumnType(Types.VARBINARY, "BLOB");

}
}
public final class DatabaseColumnDefinitions {
private DatabaseColumnDefinitions(){}
public static final String FINGERPRINT_ENCODING = "UTF-8";
public static final Charset FINGERPRINT_ENCODING_CHARSET = Charset.forName(FINGERPRINT_ENCODING);

public static final int FINGERPRINT_COLUMN_LENGTH = 16;
}
は、エンティティ、JpaRepositoriesを作りました。問題は、byte[]
マッピングを自分のエンティティで動作させることができないことです。休止状態による任意の相互作用が例外をスロー:
com.microsoft.sqlserver.jdbc.SQLServerException: The conversion from varbinary to BLOB is unsupported.
私が話していたエンティティ:VARBINARY(16) NOT NULL
、データベース上で作成した列が正しい
@Entity
@Table(
uniqueConstraints = {
@UniqueConstraint(name = "rdjsonstore_fingerprint_unique",columnNames = "fingerprint")
}
)
public class RDJsonStore implements Serializable, FingerprintIndexer {
@Column(nullable = false)
@Id
@GeneratedValue(generator = "rdjsonstore_sequence", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "rdjsonstore_sequence", sequenceName = "rdjsonstore_sequence", allocationSize = 10000)
private Long id;
@Lob
@Basic
@Column(nullable = false, length = FINGERPRINT_COLUMN_LENGTH, columnDefinition = FINGERPRINT_COLUMN)
private byte[] fingerprint;
...
が、私はからリポジトリを呼び出すしようとすると、私はエラーが備わっ取得rdJsonStoreRepository.findAll(new PageRequest(0,10))
のようなサービス:
