Does Spring's @Transactional Annotation Work on Private Methods?

Transactional Attribute Efficacy on Private Methods in Spring

Within Spring, the @Transactional annotation enables the demarcation of transactional boundaries for methods. A common question arises regarding the effectiveness of this annotation when applied to private methods within Spring beans.

The answer is straightforward: @Transactional has no effect on private methods. This is due to the proxy generator employed by Spring ignoring private methods.

To further clarify, consider the following example:

public class Bean {
  public void doStuff() {
     doPrivateStuff();
  }
  @Transactional
  private void doPrivateStuff() {

  }
}

Despite the @Transactional annotation on the private method doPrivateStuff(), it remains ineffective and does not modify the transactional behavior. This behavior is documented in Chapter 10.5.6 of the Spring Manual, which explicitly states:

"When using proxies, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings. Consider the use of AspectJ... if you need to annotate non-public methods."
