Is it possible to get exactly once processing with

问题:

https://www.confluent.io/blog/enabling-exactly-kafka-streams

and wonder that it is gonna works or not if we just put the property called "processing.guarantee" with value "exactly-once" there through properties in Spring boot application ?

In the context of your question you should look at Spring Cloud Stream as just a delegate between target system (e.g., Kafka) and your code. The binders that enable such delegation are usually implemented in such way that they propagate whatever functionality supported by the target system.
