---|---|
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. |

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.
AbstractPlatformTransactionManager.setTransactionSynchronization(int)
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).
JtaTransactionManager.setTransactionManager(javax.transaction.TransactionManager)
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).
JtaTransactionManager.setTransactionManager(javax.transaction.TransactionManager)
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.
