Constructor Detail

### DefaultTransactionAttribute

    public DefaultTransactionAttribute()

  Create a new DefaultTransactionAttribute, with default settings. Can be modified through bean property setters.

  See Also:
    `DefaultTransactionDefinition.setPropagationBehavior(int)`, `DefaultTransactionDefinition.setIsolationLevel(int)`, `DefaultTransactionDefinition.setTimeout(int)`, `DefaultTransactionDefinition.setReadOnly(boolean)`, `DefaultTransactionDefinition.setName(java.lang.String)`

### DefaultTransactionAttribute

    public DefaultTransactionAttribute(TransactionAttribute other)

  Copy constructor. Definition can be modified through bean property setters.

  See Also:
    `DefaultTransactionDefinition.setPropagationBehavior(int)`, `DefaultTransactionDefinition.setIsolationLevel(int)`, `DefaultTransactionDefinition.setTimeout(int)`, `DefaultTransactionDefinition.setReadOnly(boolean)`, `DefaultTransactionDefinition.setName(java.lang.String)`

### DefaultTransactionAttribute

    public DefaultTransactionAttribute(int propagationBehavior)

  Create a new DefaultTransactionAttribute with the the given propagation behavior. Can be modified through bean property setters.

  Parameters:
    `propagationBehavior` - one of the propagation constants in the TransactionDefinition interface
  See Also:
    `DefaultTransactionDefinition.setIsolationLevel(int)`, `DefaultTransactionDefinition.setTimeout(int)`, `DefaultTransactionDefinition.setReadOnly(boolean)`

Method Detail

### setQualifier

    public void setQualifier(String qualifier)

  Associate a qualifier value with this transaction attribute.

  This may be used for choosing a corresponding transaction manager to process this specific transaction.

### getQualifier

    public String getQualifier()

  Return a qualifier value associated with this transaction attribute.

  Specified by:
    `getQualifier` in interface `TransactionAttribute`

### rollbackOn

    public boolean rollbackOn(Throwable ex)

  The default behavior is as with EJB: rollback on unchecked exception. Additionally attempt to rollback on Error.

  This is consistent with TransactionTemplate's default behavior.

  Specified by:
    `rollbackOn` in interface `TransactionAttribute`
  Parameters:
    `ex` - the exception to evaluate
  Returns:
    whether to perform a rollback or not

### getAttributeDescription

    protected final StringBuilder getAttributeDescription()

  Return an identifying description for this transaction attribute.

  Available to subclasses, for inclusion in their `toString()` result.
