withTransaction
目的 Purpose
Allows programmatic transactions using Spring's Transaction abstraction.
使用例 Examples
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()
}
}
}
詳細 Description
The withTransaction method accepts a Closure with a TransactionStatus argument. The TransactionStatus object can be used to programmatically control rollback of the transaction.
