Answer
Self-invocation bypasses proxies, causing transactional annotations to be ignored.
In Spring, transactional proxies are created around bean methods. If a method invokes another method within the same class, the proxy is bypassed, and transactional behavior is not applied. For instance, calling a transactional method from another method within the same class will not start a new transaction or participate in an ongoing one unless the call goes through a proxy.
