    • REQUIRED

      public static final Propagation REQUIRED
      Support a current transaction, create a new one if none exists. Analogous to EJB transaction attribute of the same name.

      This is the default setting of a transaction annotation.

    • SUPPORTS

      public static final Propagation SUPPORTS
      Support a current transaction, execute non-transactionally if none exists. Analogous to EJB transaction attribute of the same name.

      Note: For transaction managers with transaction synchronization, SUPPORTS is slightly different from no transaction at all, as it defines a transaction scope 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.

      See Also:
    • MANDATORY

      public static final Propagation MANDATORY
      Support a current transaction, throw an exception if none exists. Analogous to EJB transaction attribute of the same name.
    • REQUIRES_NEW

      public static final Propagation REQUIRES_NEW
      Create a new transaction, and suspend the current transaction if one exists. Analogous to the EJB transaction attribute of the same name.

      NOTE: Actual transaction suspension will not work out-of-the-box on all transaction managers. This in particular applies to JtaTransactionManager, which requires the jakarta.transaction.TransactionManager to be made available to it (which is server-specific in standard Jakarta EE).

      See Also:
    • NOT_SUPPORTED

      public static final Propagation NOT_SUPPORTED
      Execute non-transactionally, suspend the current transaction if one exists. Analogous to EJB transaction attribute of the same name.

      NOTE: Actual transaction suspension will not work out-of-the-box on all transaction managers. This in particular applies to JtaTransactionManager, which requires the jakarta.transaction.TransactionManager to be made available to it (which is server-specific in standard Jakarta EE).

      See Also:
    • NEVER

      public static final Propagation NEVER
      Execute non-transactionally, throw an exception if a transaction exists. Analogous to EJB transaction attribute of the same name.
    • NESTED

      public static final Propagation NESTED
      Execute within a nested transaction if a current transaction exists, behave like REQUIRED otherwise. There is no analogous feature in EJB.

      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. Some JTA providers might support nested transactions as well.

    • values

      public static Propagation[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static Propagation valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
