Spring transactions

This repo contains examples of Spring transactions usage.

Where to start

To start I recommend clone repo and go through code starting from test classes:

• MyAnnotatedServiceTest - contains usage of @Transactional annotation
• MyAnnotatedServicePropagationTest - again @Transactional annotation but with couple of examples of propagation setting.
• MyTxTemplateServiceTest - @Transactional is not only way of creating transaction in Spring very simple usage of TransactionTemplate -IsolationTest - lets check how @Transactional meets isolation levels (it depends on particular DB vendor - tested with H2 and MySQL - if u want to change DB just go to application.yaml and put url and add connector to pom)
