Class AbstractLobType

java.lang.Object

org.springframework.orm.hibernate3.support.AbstractLobType

All Implemented Interfaces:

UserType

Direct Known Subclasses:

BlobByteArrayType, BlobSerializableType, BlobStringType, ClobStringType

Deprecated.

as of Spring 4.3, in favor of Hibernate 4.x/5.x

@Deprecated
public abstract class AbstractLobType
extends Object
implements UserType

Abstract base class for Hibernate UserType implementations that map to LOBs. Retrieves the LobHandler to use from LocalSessionFactoryBean at config time.

For writing LOBs, either an active Spring transaction synchronization or an active JTA transaction (with "jtaTransactionManager" specified on LocalSessionFactoryBean or a Hibernate TransactionManagerLookup configured through the corresponding Hibernate property) is required.

Offers template methods for setting parameters and getting result values, passing in the LobHandler or LobCreator to use.

Since:

1.2
