Spring nested transactions

Question

In my Spring Boot project I have implemented following service method:

@Transactional
public boolean validateBoard(Board board) {
    boolean result = false;

This documentation covers your problem - https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/data-access.html#transaction-declarative-annotations

In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional. Also, the proxy must be fully initialized to provide the expected behaviour so you should not rely on this feature in your initialization code, i.e. @PostConstruct.

However, there is an option to switch to AspectJ mode
