org.springframework.jdbc.datasource
Class JdbcTransactionObjectSupport

java.lang.Object
  org.springframework.jdbc.datasource.JdbcTransactionObjectSupport

All Implemented Interfaces:: SavepointManager, SmartTransactionObject

public abstract class JdbcTransactionObjectSupport
extends Object
implements SavepointManager, SmartTransactionObject
extends Object
implements SavepointManager, SmartTransactionObject

Convenient base class for JDBC-aware transaction objects. Can contain a ConnectionHolder, and implements the SavepointManager interface based on that ConnectionHolder.

Allows for programmatic management of JDBC 3.0 Savepoints. Spring's DefaultTransactionStatus will automatically delegate to this, as it autodetects transaction objects that implement the SavepointManager interface.

Note that savepoints are only supported for drivers which support JDBC 3.0 or higher.
