All Implemented Interfaces:

TransactionAttribute, TransactionDefinition

public class RuleBasedTransactionAttribute

extends DefaultTransactionAttribute

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).
The TransactionAttributeEditor property editor creates objects of this class.
