Servicecomb with eureka

[szattila98]

Hello, I am trying to make the Saga part of Servicecomb work with Spring Cloud Netflix Eureka. Sadly nothing happens when I send a request which should start the Saga and set the transaction in motion. The Alpha database tables are empty too and the compensation method (which should be running because in the @SagaStart annotated method there is a RuntimeException thrown) does not run. No logs indicate that anything happened at all. What I did:

• Alpha successfully registers to Eureka, so up until then there should not be a mistake on my part
• Then the Omega dependency and Feign transport dependency is added to two services, and the alpha.cluster.register.type: eureka property is set in their props files
• Then a serviceA service layer method is annotated with @SagaStart and @Transactional, it calls a ServiceB method through a Feign client interface
• ServiceB service layer method is annotated with @Compensable, @Transactional and it has a compensation method with the same arguments and return type

What am I missing?

Could you share some debug logging messages ? and I think it could be helpful for us to take a close look. Also it could be useful if you can share us with a simple re-producer project.

Thanks !

Sure, here they are. I included a readme in the re-producer project with some details, maybe it will help. The logs are about the relevant services, the feedback-service should start the saga and call the user-service, which saves a record, then return to the feedback-service, where a RuntimeException is thrown, and in the user-service the compensation method should be called because of that. The re-producer project follows more or less the same logic.

Thanks for the fast response!

Great and I will take a look.

Hello again, did you have the chance to take a look at it?
