Why Redis Increment Returns Null When Using @Transactional with Transaction Support in Spring Boot

The production failure where a customer‑service event creation stopped each morning was traced to RedisTemplate’s increment returning null because @Transactional combined with enabled Redis transaction support caused the command to be queued in a MULTI/EXEC block, which is fixed by using separate non‑transactional and transactional StringRedisTemplate beans.

Alibaba Java Interview: Does annotating the same Spring Boot service method with @Transactional and @Async cause transaction failure?

In Spring Boot, using @Transactional and @Async on the same service method does not invalidate the transaction, but the asynchronous execution runs in a separate thread with its own transaction, isolated from the original thread's transaction due to AOP interceptor ordering.
