withTransaction

Purpose

Allows programmatic transactions using Spring's Transaction Abstraction and a block.

Examples

Account.withTransaction { status ->
	def source = Account.get(params.from)
	def dest = Account.get(params.to)
	def amount = params.amount.toInteger()
	if(source.active) {
		source.balance -= amount
		if(dest.active) {
			dest.amount += amount
		}
		else {
			status.setRollbackOnly()
		}
	}	
}

Description

The withTransaction method uses a block or closure that gets passed Spring TransactionStatus object. The TransactionStatus object can be used to programmatically control rollback of the transaction.
