When & How to use Spring boot @Transactional?


The @Transactional annotation is probably the most randomly used annotation in the whole Java development world – and it’s terrifying!

There are many misconception about how & and where to use @Transactional annotations in spring boot application. I came across this awesome tutorial and it is worth reading it.

Common pitalls are:

  • Pitfall #1: Redundant @Transactional or JPA calls
  • Pitfall #2: @Transactional ignored?
  • Pitfall #3: @Transactional(readOnly = true)
  • Pitfall #4: Rollbacks
  • Pitfall #5: Propagation modes and isolation levels
