Unexpected Retry Occurs Even After Catching Exception Inside @Transactional Method

[ausada-c]

Environment:

Java Spring Boot

spring-boot-starter-parent version: 3.2.11

mq-jms-spring-boot-starter version: 3.3.3

Problem Description:
In my main function, I have added the annotation @transactional (org.springframework.transaction.annotation.Transactional).
Inside this main function, I call another service method that is also annotated with @transactional.

When an exception of type org.springframework.dao.DuplicateKeyException is thrown, even though I already have a try-catch block to catch this exception in the main function, the function still keeps retrying automatically.

Question:
Why does the function retry even after the exception has been caught in the main function?

This sounds like something you'd need to ask in one of the main Spring repository issues. Though don't be surprised if noone is prepared to watch a random video - real text is much more usable.
