Spring Boot Trasnsaction Stop Auto Commit or Rollback when some other Transaction Fails

Question

Everone,

I am learning springboot with Mysql and trying to concentrate on Transactions. I am following the below link for guidance :

https://github.com/spring-guides/gs-managing-transactions/tree/master/complete

When i execute the first transaction Alice, Bob and Carol gets saved.

When i execute the Second transaction Chris or Samuel gets discarded because Samuel has violated DB constraints.

All i want to know now is, 1. Is there a way to rollback the first Transaction when second Transaction Fails ? 2. Save all transaction when everything is completed...

Answer 1

Yes.
You just have to declare both transactions into 2 different methods and annotate them with @Transactional (propagation=Propagation.REQUIRED) from the first transaction method.

For more details study transaction propagation : https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/transaction/annotation/Propagation.html .
