If I have a @Transactional -annotation on a private method in a Spring bean, does the annotation have any effect?
If the @Transactional
annotation is on a public method, it works and open a transaction.
public class Bean {
public void doStuff() {
doPrivateStuff();
}
@Transactional
private void doPrivateStuff() {
}
}
...
Bean bean = (Bean)appContext.getBean("bean");
bean.doStuff();
The answer your question is no - @Transactional
will have no effect if used to annotate private methods. The proxy generator will ignore them.
This is documented in Spring Manual chapter 10.5.6:
Method visibility and
@Transactional
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 (see below) if you need to annotate non-public methods.
