Class JdbcTransactionObjectSupport

java.lang.Object

org.springframework.jdbc.datasource.JdbcTransactionObjectSupport

All Implemented Interfaces:

Flushable, org.springframework.transaction.SavepointManager, org.springframework.transaction.support.SmartTransactionObject

public abstract class JdbcTransactionObjectSupport
extends Object
implements org.springframework.transaction.SavepointManager, org.springframework.transaction.support.SmartTransactionObject

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

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

Since:

1.1
