(Quick Reference)



Allows programmatic transactions using Spring's Transaction abstraction.


Account.withTransaction { status ->

def source = Account.get(params.from) def dest = Account.get(params.to)

int amount = params.amount.toInteger() if (source.active) { source.balance -= amount

if (dest.active) { dest.amount += amount } else { status.setRollbackOnly() } } }

Named arguments may optionally be passed as an argument to control attributes of the transaction.

// the keys in the Map must correspond to properties
// of org.springframework.transaction.support.DefaultTransactionDefinition

Account.withTransaction([propagationBehavior: TransactionDefinition.PROPAGATION_REQUIRES_NEW, isolationLevel: TransactionDefinition.ISOLATION_REPEATABLE_READ]) { // … }


The withTransaction method accepts a Closure with a TransactionStatus argument. The TransactionStatus object can be used to programmatically control rollback of the transaction.

Refer to the user guide section of Programmatic Transactions for more information.
