Class RuleBasedTransactionAttribute

java.lang.Object
  org.springframework.transaction.support.DefaultTransactionDefinition
      org.springframework.transaction.interceptor.DefaultTransactionAttribute
          org.springframework.transaction.interceptor.RuleBasedTransactionAttribute

All Implemented Interfaces:

Serializable, TransactionAttribute, TransactionDefinition

public class RuleBasedTransactionAttribute
extends DefaultTransactionAttribute
implements Serializable

TransactionAttribute implementation that works out whether a given exception should cause transaction rollback by applying a number of rollback rules, both positive and negative. If no rules are relevant to the exception, it behaves like DefaultTransactionAttribute (rolling back on runtime exceptions).

TransactionAttributeEditor creates objects of this class.

Constructor Summary

RuleBasedTransactionAttribute()
Create a new RuleBasedTransactionAttribute, with default settings.

Constructor Detail

RuleBasedTransactionAttribute

public RuleBasedTransactionAttribute()

Create a new RuleBasedTransactionAttribute, 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), setRollbackRules(java.util.List)

RuleBasedTransactionAttribute

public RuleBasedTransactionAttribute(RuleBasedTransactionAttribute 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), setRollbackRules(java.util.List)

RuleBasedTransactionAttribute

public RuleBasedTransactionAttribute(int propagationBehavior,
                                     List rollbackRules)

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

rollbackRules - the list of RollbackRuleAttributes to apply

See Also:

DefaultTransactionDefinition.setIsolationLevel(int), DefaultTransactionDefinition.setTimeout(int), DefaultTransactionDefinition.setReadOnly(boolean)

Method Detail

setRollbackRules

public void setRollbackRules(List rollbackRules)

Set the list of RollbackRuleAttribute objects (and/or NoRollbackRuleAttribute objects) to apply.

See Also:

RollbackRuleAttribute, NoRollbackRuleAttribute

getRollbackRules

public List getRollbackRules()

Return the list of RollbackRuleAttribute objects (never null).

rollbackOn

public boolean rollbackOn(Throwable ex)

Winning rule is the shallowest rule (that is, the closest in the inheritance hierarchy to the exception). If no rule applies (-1), return false.

Specified by:

rollbackOn in interface TransactionAttribute

Overrides:

rollbackOn in class DefaultTransactionAttribute

Parameters:

ex - the exception to evaluate

Returns:

whether to perform a rollback or not

See Also:

TransactionAttribute.rollbackOn(java.lang.Throwable)

toString

public String toString()

Description copied from class: DefaultTransactionDefinition

Return an identifying description for this transaction definition.

The format matches the one used by TransactionAttributeEditor, to be able to feed toString results into bean properties of type TransactionAttribute.

Has to be overridden in subclasses for correct equals and hashCode behavior. Alternatively, DefaultTransactionDefinition.equals(java.lang.Object) and DefaultTransactionDefinition.hashCode() can be overridden themselves.

Overrides:

toString in class DefaultTransactionDefinition
