org.springframework.orm.hibernate3.support.BlobByteArrayType
public class BlobByteArrayType
Hibernate UserType implementation for byte arrays that get mapped to BLOBs. Retrieves the LobHandler to use from LocalSessionFactoryBean at config time.
Can also be defined in generic Hibernate mappings, as DefaultLobCreator will work with most JDBC-compliant database drivers. In this case, the field type does not have to be BLOB: For databases like MySQL and MS SQL Server, any large enough binary type will work.
