I am exploring spring transactions and after going through the spring docs and the following link i still have few questions. If I have a parent method with Propogation.REQUIRED which is calling 3 methods with Propogation.REQUIRES_NEW as follows:

//@Transactional(isolation=Isolation.READ_COMMITTED, propagation = Propagation.REQUIRED)
public Contact saveContactInSteps(Contact contact, String newFirstName, String newLastName, Date bDate) throws Exception {
    contact.setFirstName(newFirstName);
    try {
        updateContactFirstName(contact);
    } catch (Exception e) {
        LOG.error("Contact first name could not be saved !!");
        e.printStackTrace();
        throw e;
    }

    contact.setLastName(newLastName);
    try {
        updateContactLastName(contact);
    } catch (Exception e) {
        LOG.error("Contact Last name could not be saved !!");
        e.printStackTrace();
        throw e;
    }

    contact.setBirthDate(bDate);
    updateContactBday(contact);

    return contact;
}

public Contact saveById(Contact contact) {
    sessionFactory.getCurrentSession().saveOrUpdate(contact);
    LOG.info("Contact " + contact + " saved successfully");
    return contact;
}

//@Transactional(isolation=Isolation.READ_COMMITTED, propagation = Propagation.REQUIRES_NEW)
public Contact updateContactFirstName(Contact contact) throws Exception {
    throw new Exception("Cannot update first name");
    //sessionFactory.getCurrentSession().saveOrUpdate(contact);
    //LOG.info("Contact First name saved successfully");
    //return contact;
}

//@Transactional(isolation=Isolation.READ_COMMITTED, propagation = Propagation.REQUIRES_NEW)
public Contact updateContactLastName(Contact contact) throws Exception {
    throw new Exception("Cannot update last name");
    //sessionFactory.getCurrentSession().saveOrUpdate(contact);
    //LOG.info("Contact " + contact + " saved successfully");
    //return contact;
}

//@Transactional(isolation=Isolation.READ_COMMITTED, propagation = Propagation.REQUIRES_NEW)
public Contact updateContactBday(Contact contact) {
    sessionFactory.getCurrentSession().saveOrUpdate(contact);
    LOG.info("Contact Birth Date saved successfully");
    return contact;
}

Whenever i process the parent method i.e. saveContactInSteps, even the last name is getting updated in database. I am not sure how that is happening. If i throw the exception from first child method nothing gets updated. Is it because of the fact that i am setting the attributes i.e. names and birthdate in the parent method ? Even if i am setting the attributes in the parent method, i am not letting the parent method complete as well. Does the isolation level play any part here ? I believe it's for concurrent transactions ? Is there something i am missing ?

EDIT 1:

After going through the article i did realize what i was missing. I needed AOP proxies in place which i have added as follows:

<aop:config>
    <aop:pointcut
        expression="execution(* org.pack.spring.transactions.ContactService.*(..))"
        id="updateOperation" />
    <aop:advisor pointcut-ref="updateOperation" advice-ref="saveUpdateAdvice" />
</aop:config>

<tx:advice id="saveUpdateAdvice">
    <tx:attributes>
        <tx:method name="update*" propagation="REQUIRES_NEW" isolation="DEFAULT" rollback-for="Exception"/>
        <tx:method name="save*" propagation="REQUIRED" isolation="DEFAULT" rollback-for="Exception"/>
    </tx:attributes>
</tx:advice>

Log output is as follows:

Note - I have removed the @Transactional annotations from the methods as i am relying on proxy to achieve the same.

From the logs, it seems that the proxies are getting created but again as pointed out in the comment, will the 3 methods invoked from saveContactInSteps not have a transaction against them as mentioned in the documentation :

In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional. Also, the proxy must be fully initialized to provide the expected behaviour so you should not rely on this feature in your initialization code, i.e. @PostConstruct

Is there a way to get around this ? Is AspectJ the only solution ?

    Calling a method from the same bean won't start another transaction. Transaction hndling is proxy-based. You need to go through a proxy to have Spring start a new transaction. This is explained in the Spring documentation. BTW, don't read the Spring 3.x documentation. The current version of Spring is 5.c. 3.x is obsolete. Also a non-runtime exception doesn't cause a rollback. https://docs.spring.io/spring/docs/current/spring-framework-reference/data-access.html#transaction – JB Nizet Jan 22 '18 at 17:14
  • Ok. After re-reading the docs, it looks like using @Transactional by default uses mode = proxy. So, going by annotation based approach, how can i achieve what i want to achieve ? – Adithya Jan 28 '18 at 11:44

    Don't call methods from the same bean to start a new transaction. Call a method from **another** bean, injected into the first one. – JB Nizet Jan 28 '18 at 11:45
  • Thanks @JBNizet ! – Adithya Jan 30 '18 at 10:24
