@Documented @Retention(value=RUNTIME) @Target(value=METHOD) public @interface StartSaga

method can trigger the
creation of a new Saga instance.
When a Saga is started due to an invocation on a StartSaga annotated method, the association of the annotated method
and the actual property's value are used to define a AssociationValue for the created saga. Thus, a method with this
definition:
@StartSaga(forceNew=true)
@SageEventHandler(associationProperty="orderId")
public void
handleOrderCreated(OrderCreatedEvent event)
event.getOrderId()
.
