Answer
Self-invocation bypasses Spring's transactional proxy mechanism.
In Spring Boot, transaction management is often handled by proxies. When a transactional method calls another method within the same class, it does not go through the proxy, potentially leading to transaction boundaries being ignored. This can result in unexpected data commits or rollbacks. For instance, if 'processPayment' in 'PaymentService' internally calls 'logTransaction' directly, it won't benefit from transaction management unless 'logTransaction' is externally invoked.
