Metode setSavePoint transaksi Grails di mysql menyebabkan pengecualian

Secara default, manajer transaksi untuk hibernasi dan MySQL tidak mengaktifkan titik penyimpanan.

Di BootStrap.groovy tambahkan berikut ini:

transactionManager.setNestedTransactionAllowed(true)

Kemudian dalam bertransaksi Anda dapat melakukan hal berikut:

Thing.withTransaction { status ->
  //Do some work and a save
  def savePoint = status.createSavepoint()
  //do other work
  if(checkOk)
  {
    //Everything worked so don't need the save point anymore
    status.releaseSavepoint(savePoint)
  }
  else
  {
    //The other work did not work so rollback from it.
    status.rollbackToSavepoint(savePoint)
  }

}
