Class Overview
Interface that specifies an API to programmatically manage transaction savepoints in a generic fashion. Extended by TransactionStatus to expose savepoint management functionality for a specific transaction.
Note that savepoints can only work within an active transaction. Just use this programmatic savepoint handling for advanced needs; else, a subtransaction with PROPAGATION_NESTED is preferable.
This interface is inspired by JDBC 3.0's Savepoint mechanism but is independent from any specific persistence technology.

Public Methods
public abstract Object createSavepoint ()
Create a new savepoint. You can roll back to a specific savepoint
via rollbackToSavepoint, and explicitly release a
savepoint that you don't need anymore via releaseSavepoint.
Note that most transaction managers will automatically release savepoints at transaction completion.
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
public abstract void releaseSavepoint (Object savepoint)
Explicitly release the given savepoint.
Note that most transaction managers will automatically release savepoints at transaction completion.
Implementations should fail as silently as possible if proper resource cleanup will still happen at transaction completion.
Parameters
| savepoint | the savepoint to release |
|---|
Throws
| NestedTransactionNotSupportedException | if the underlying transaction does not support savepoints |
|---|---|
| TransactionException | if the release failed |
See Also
public abstract void rollbackToSavepoint (Object savepoint)
Roll back to the given savepoint. The savepoint will be automatically released afterwards.
Parameters
| savepoint | the savepoint to roll back to |
|---|
Throws
| NestedTransactionNotSupportedException | if the underlying transaction does not support savepoints |
|---|---|
| TransactionException | if the rollback failed |
