$ mvn -pl saga test -Dtest=ChoreographyCompensationTest

(same saga, stock deliberately too low: 1 unit on hand, order asks for 5)
|
|
|
|
Order 1 status: CANCELLED
|
|
Stock remaining for GADGET-1 (untouched by the rejected reservation): 1
|
|
Payment record status: REFUNDED
|
|
|

InventoryChoreographyListener's tryReserve() refused before touching the stock map at all --
|
|
the 1 unit is exactly where it started. That rejection published InventoryRejected, which
|
|
PaymentChoreographyListener is also subscribed to; it refunded the payment it had reserved
|
|
earlier and published PaymentRefunded, which OrderChoreographyListener used to cancel the
|
|
order. The compensating transaction (the refund) is ordinary code in a class that already
|
|
existed for an unrelated reason -- nothing new coordinates it.
