Spring @Transactional in an Aspect (AOP)


Spring @Transactional in an Aspect (AOP)

I wish did fix the issue. In Spring, @Transactional works by creating a proxy of your class (either a Java or cglib proxy) and intercepting the annotated method. This means that @Transactional doesn't work if you are calling the annotated method from another method of the same class.
Just move the createRecord method to a new class (don't forget to make it a Spring bean too) and it will work.

To fix this issue Your aspect if flawed
You must always return Object from an around aspect Never catch and swallow an exception
code :
public void logProcess(ProceedingJoinPoint joinPoint) throws Throwable  { ... }
@Aspect
public class LoggingAspect {
    public Object logProcess(ProceedingJoinPoint joinPoint) throws Throwable {
        <!-- some code before -->
        try {
            Object result = joinPoint.proceed();
            <!-- some code after -->
            return result;
        } catch (Exception e) {
            log.info(e.getMessage());
            <!-- some code here -->     
            throw e;
        }   
    }
}

this will help As mentionned in M.Deinum comment, I forgot the @EnableAspectJAutoProxy in my configuration class, this fixed the problem.
Will flag this as the right answer when allowed.

help you fix your problem There is no such thing as transactional annotations or the like in slick. Your second "do not want" is actually the way to go. It's totally reasonable to return DBIO[User] from your DAO which does not defeat their purpose at all. It's the way slick works.
code :
class UserController @Inject(userService: UserService) {
  def register(userData: UserData) = {
    userService.save(userData).map(result => Ok(result))
  }
}

class UserService @Inject(userDao: UserDao, addressDao: AddressDao) {
  def save(userData: UserData): Future[User] = {
    val action = (for {
      savedUser <- userDao.save(userData.toUser)
      savedAddress <- addressDao.save(userData.addressData.toAddress)
      whatever <- DBIO.successful(nonDbStuff)
    } yield (savedUser, savedAddress)).transactionally

    db.run(action).map(result => result._1.copy(result._2))
  }
}

class SlickUserDao {
  def save(user: User): DBIO[User] = {
    (UserSchema.users returning UserSchema.users).insertOrUpdate(user)
  }
}
Spring boot with spring @Transactional works without enabling transactional management

should help you out Yes, this is enabled as long as you have spring-tx and some transactional resource in your application. Effectively if you are using spring-boot-starter-jdbc or spring-boot-starter-data-jpa, Spring Boot will configure a DataSource for you, start Hibernate (in the latter case) and configure transaction management.
Not all "Enable" annotations require to be explicitly set. When there is a reasonable amount of things that we can check to validate it makes sense to configure that for you, we'll do it. In this case, if you have a DataSource you must probably want to have transactions. If you have JPA (and no JTA infrastructure), you probably want a JpaTransactionManager). If we auto-configure that, the easiest way to use it is via @Transactional so we'll enable that in that case as well.

it fixes the issue I am in the process of adding Spring declarative transactions via the @Transactional annotation to an existing Java project. , Strange, it sounds like you have this configuration:
