JdbcTransactionObjectSupport (Spring Framework) - Spring Framework 1.2.9 API 文档英文版
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
Convenient base class for JDBC-aware transaction objects.
Can contain a ConnectionHolder, and implements the SavepointManager
interface based on that ConnectionHolder.
Implements the SavepointManager interface to allow for programmatic
management of JDBC 3.0 Savepoints. DefaultTransactionStatus will
automatically delegate to this, as it auto-detects transaction objects
that implement the SavepointManager interface.
Note that savepoints are only supported for JDBC 3.0.
- Since:
- 1.1

- This implementation creates a JDBC 3.0 Savepoint and returns it.
- Specified by:
createSavepoint
in interface SavepointManager
- Returns:
- a savepoint object, to be passed into rollbackToSavepoint
or releaseSavepoint
- Throws:
NestedTransactionNotSupportedException
- if the underlying
transaction does not support savepoints
TransactionException
- if the savepoint could not be created,
for example because the transaction is not in an appropriate state- See Also:
Connection.setSavepoint()
rollbackToSavepoint
public void rollbackToSavepoint(Object savepoint)
throws TransactionException
- This implementation rolls back to the given JDBC 3.0 Savepoint.
- Specified by:
rollbackToSavepoint
in interface SavepointManager
- Parameters:
savepoint
- the savepoint to roll back to
- Throws:
NestedTransactionNotSupportedException
- if the underlying
transaction does not support savepoints
TransactionException
- if the rollback failed- See Also:
Connection.rollback(java.sql.Savepoint)
releaseSavepoint
public void releaseSavepoint(Object savepoint)
throws TransactionException
- This implementation releases the given JDBC 3.0 Savepoint.
- Specified by:
releaseSavepoint
in interface SavepointManager
- Parameters:
savepoint
- the savepoint to release
- Throws:
NestedTransactionNotSupportedException
- if the underlying
transaction does not support savepoints
TransactionException
- if the release failed- See Also:
Connection.releaseSavepoint(java.sql.Savepoint)
