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 Details

setDescriptor

public void setDescriptor(@Nullable String descriptor)

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

Since:

4.3.4

getDescriptor

public @Nullable String getDescriptor()

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

Since:

4.3.4

setTimeoutString

public void setTimeoutString(@Nullable String timeoutString)

Set the timeout to apply, if any, as a String value that resolves to a number of seconds.

Since:

5.3

See Also:

• DefaultTransactionDefinition.setTimeout(int)
• resolveAttributeStrings(org.springframework.util.StringValueResolver)

getTimeoutString

public @Nullable String getTimeoutString()

Return the timeout to apply, if any, as a String value that resolves to a number of seconds.

Since:

5.3

See Also:

• DefaultTransactionDefinition.getTimeout()
• resolveAttributeStrings(org.springframework.util.StringValueResolver)

setQualifier

public void setQualifier(@Nullable 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

See Also:

• resolveAttributeStrings(org.springframework.util.StringValueResolver)

getQualifier

public @Nullable String getQualifier()

Return a qualifier value associated with this transaction attribute.

Specified by:

getQualifier in interface TransactionAttribute

Since:

3.0

setLabels

public void setLabels(Collection<String> labels)

Associate one or more labels with this transaction attribute.

This may be used for applying specific transactional behavior or follow a purely descriptive nature.

Since:

5.3

See Also:

• resolveAttributeStrings(org.springframework.util.StringValueResolver)

getLabels

public Collection<String> getLabels()

Description copied from interface: TransactionAttribute

Return labels associated with this transaction attribute.

This may be used for applying specific transactional behavior or follow a purely descriptive nature.

Specified by:

getLabels in interface TransactionAttribute

rollbackOn

public boolean rollbackOn(Throwable ex)

The default behavior is as with EJB: rollback on unchecked exception (RuntimeException), assuming an unexpected outcome outside 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>)

resolveAttributeStrings

public void resolveAttributeStrings(@Nullable StringValueResolver resolver)

Resolve attribute values that are defined as resolvable Strings: setTimeoutString(java.lang.String), setQualifier(java.lang.String), setLabels(java.util.Collection<java.lang.String>). This is typically used for resolving "${...}" placeholders.

Parameters:

resolver - the embedded value resolver to apply, if any

Since:

5.3

getAttributeDescription

protected final StringBuilder getAttributeDescription()

Return an identifying description for this transaction attribute.

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