Mixing
Pointcut or Aspect Around All Service Methods with Annotation @Transactional(readOnly = false)
Is it possible to use Spring AOP or AspectJ to intercept all Service methods (contained in classes in the com.app.service.* package) having the annotation
@Transactional(readOnly = false)
(other elements possible as well in Spring's @Transactional annotation, but we only care about readOnly = false).
I could only find examples pertaining to pointcuts with simple Annotations, or @Annotation(value).
My preference would be to use straight Spring, if possible.
It would probably be something like the below, but not sure about the syntax.
@Around("execution(* com.app.service..*.*(..))" && @Transactional[??])
java spring aop aspectj pointcut

That should be possible. I've worked sometime back on spring and I remember using a xml configuration to achieve the same. We used to mark all transactions as read only and explicitly configure required ones to be able write.

Unfortunately no easy way to do that. Even when we have an Annotation-based pointcut, e.g.
@Aspect
@Component
@EnableAspectJAutoProxy
public class WriteTransactionAspectBean {
@Before("@annotation(org.springframework.transaction.annotation.Transactional)")
public void test(org.springframework.transaction.annotation.Transactional t) {
System.out.println("TEST");
}
}
the issue is the Annotations aren't our own, they come from an external JAR (Hibernate). This would require Load-Time Weaving or some other difficult workaround.
Aspectj: intercept method from external jar
But to make things even worse, Annotations need RetentionPolicy=RUNTIME in order to be "discovered" by Pointcuts. And we would need to go thru every method and add this specification to every @Transactional. There's no way to automatically make all @Transactional's Runtime-retainable in the application.

This answer is plain wrong. The@Transactionalannotation is defined with runtime scope as you can clearly see in the corresponding JavaDoc. Otherwise Spring could not do anything with it either.

You want to use a pointcut like this:
execution(@org.springframework.transaction.annotation.Transactional(readOnly = false) * com.app.service..*.*(..))

The issue I came across with this one is, I had to get aTransactional targument to examine the object. And whenever I had this argument, the app wouldn't start (there was an error). It worked when I had a simple signature, without the actualTransactional tobject.
