Constructor Detail

DefaultTransactionAttribute

public DefaultTransactionAttribute()

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

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 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(java.lang.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.

Since:

3.0

getQualifier

public java.lang.String getQualifier()

Return a qualifier value associated with this transaction attribute.

Specified by:

getQualifier in interface TransactionAttribute

Since:

3.0

setDescriptor

public void setDescriptor(java.lang.String descriptor)

Set a descriptor for this transaction attribute, e.g. indicating where the attribute is applying.

Since:

4.3.4

getDescriptor

public java.lang.String getDescriptor()

Return a descriptor for this transaction attribute, or null if none.

Since:

4.3.4

rollbackOn

public boolean rollbackOn(java.lang.Throwable ex)

The default behavior is as with EJB: rollback on unchecked exception (RuntimeException), assuming an unexpected outcome outside of any business rules. Additionally, we also attempt to rollback on Error which is clearly an unexpected outcome as well. By contrast, a checked exception is considered a business exception and therefore a regular expected outcome of the transactional business method, i.e. a kind of alternative return value which still allows for regular completion of resource operations.

This is largely consistent with TransactionTemplate's default behavior, except that TransactionTemplate also rolls back on undeclared checked exceptions (a corner case). For declarative transactions, we expect checked exceptions to be intentionally declared as business exceptions, leading to a commit by default.

Specified by:

rollbackOn in interface TransactionAttribute

Parameters:

ex - the exception to evaluate

Returns:

whether to perform a rollback or not

See Also:

TransactionTemplate.execute(org.springframework.transaction.support.TransactionCallback<T>)

getAttributeDescription

protected final java.lang.StringBuilder getAttributeDescription()

Return an identifying description for this transaction attribute.

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