The Saga design pattern is a way to manage data consistency across microservices in distributed transaction scenarios. A saga is a sequence of transactions that updates each service and publishes a message or event to trigger the next transaction step.

@SuppressWarnings("common-java:DuplicatedBlocks")
public class PurchaseStockSaga implements Saga<PurchaseStockSagaState,PurchaseStockSagaData> {
   private SagaStateMachine<PurchaseStockSagaState,PurchaseStockSagaData>  stockStateMachine;

   @PostConstruct
    public void initializeStateMachine(){
       this.stockStateMachine = starting(this::initialize)
               .inState(PurchaseStockSagaState.PURCHASE_STOCK_STARTED)
            .replyFrom(PaymentServiceProxy.makePayment)
            .onReply(Success.class, this::handleStockPurchaseSuccessful)
            .onReply(Failure.class, this::handlePaymentFailed);      
    }

@Override
public SagaStateMachine<PurchaseStockSagaState,PurchaseStockSagaData>     getStockStateMachine(){
  
    return stockStateMachine;

}
