Enum Constant Summary | |
---|---|
MANDATORY
Support a current transaction, throw an exception if none exists. |
|
NESTED
Execute within a nested transaction if a current transaction exists, behave like PROPAGATION_REQUIRED else. |
|
NEVER
Execute non-transactionally, throw an exception if a transaction exists. |
|
NOT_SUPPORTED
Execute non-transactionally, suspend the current transaction if one exists. |
|
REQUIRED
Support a current transaction, create a new one if none exists. |
|
REQUIRES_NEW
Create a new transaction, suspend the current transaction if one exists. |
|
SUPPORTS
Support a current transaction, execute non-transactionally if none exists. |

Enum Constant Detail |

public static final Propagation REQUIRED
This is the default setting of a transaction annotation.
public static final Propagation SUPPORTS
Note: For transaction managers with transaction synchronization, PROPAGATION_SUPPORTS is slightly different from no transaction at all, as it defines a transaction scopp that synchronization will apply for. As a consequence, the same resources (JDBC Connection, Hibernate Session, etc) will be shared for the entire specified scope. Note that this depends on the actual synchronization configuration of the transaction manager.
public static final Propagation MANDATORY
public static final Propagation REQUIRES_NEW
Note: Actual transaction suspension will not work on out-of-the-box
on all transaction managers. This in particular applies to JtaTransactionManager,
which requires the javax.transaction.TransactionManager
to be
made available it to it (which is server-specific in standard J2EE).
public static final Propagation NOT_SUPPORTED
Note: Actual transaction suspension will not work on out-of-the-box
on all transaction managers. This in particular applies to JtaTransactionManager,
which requires the javax.transaction.TransactionManager
to be
made available it to it (which is server-specific in standard J2EE).
public static final Propagation NEVER
public static final Propagation NESTED
Note: Actual creation of a nested transaction will only work on specific transaction managers. Out of the box, this only applies to the JDBC DataSourceTransactionManager when working on a JDBC 3.0 driver. Some JTA providers might support nested transactions as well.
