I get a NullPointerException on when running this test:

import javax.transaction.Transactional;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = MainConfig.class)
@Transactional
public class CustomerRepositoryTest {

    @Autowired
    private CustomerRepository customerRepository;

    @Test
    public void testCustomerConfig() {

    }

    @Test
    public void save() {
        Customer c = new Customer();
        c.setName("test-name");
        c.setAge(30);
        Customer cust = customerRepository.save(c);
        Assert.assertNotNull(cust.getId());
    }

}

The null object seems to be the transactionManager, so I suppose it's not properly injected. Relevant part of the stacktrace is here:

Full code is available on Github: https://github.com/fabiomaffioletti/mul-at I could not find any working example, and even after looking at the Spring blog article I cannot get it to work. Has anyone any hint?

I think the CMTTransaction in the stack trace is the clue: Hibernate thinks you are in a container. I also think it might work if you just remove the javax.persistence.transactionType=JTA property.

Thank you Dave, I modified and pushed the modification as you suggested. I don't get the NPE anymore, but the entity is still not persisted. I added the console log to the main post to help identify the problem. – Tiloine
I can have a closer look if you include a README with precise instructions for creating test databases. Why not go with in-memory for testing? – Withstand
Dave, I just pushed the in memory db implementation on the master branch of the github repo. I made another branch called "mysql-db" with a README containing how to create mysql databases. – Tiloine
Thanks. I can't see anything wrong with it - looks pretty vanilla. If you crank up the logging you can see the transaction saying it is committing, but clearly the entity manager never got the message. – Withstand
I can also see something like "atomikos connection proxy for conn7: url=jdbc:h2:order user=: WARNING: transaction manager not running?" which is weird to me. I just put on github a test I made a while ago with a previous version of spring (3.2.3 - no spring-boot, no spring-data-jpa) which involves two databases and activemq and it seems to work well. Unfortunately I don't have an in memory implementation for this one, but you can see the code here: github.com/fabiomaffioletti/mul-at-spring-3 Do you have any other suggestion to give me? – Tiloine
I don't know really. We can chat if you like: chat.stackoverflow.com/rooms/info/50400/… – Withstand
I would, but I have no enough reputation to write on it – Tiloine
Sorry, I added you to the chat, but you need 20 reps. It's easy to get that. – Withstand
The WARNING: transaction manager not running? was due to the fact that the transactionManager was not created before the Customer/OrderConfig (I read that this can happen using @ComponentScan annotations). I solved it by declaring those two classes dependant on the transactionManager bean. @DependsOn("transactionManager"). But the entityManager still does not get notified. BTW I have enough reputation to write on the chat now. – Tiloine
See goo.gl/jpmZ0f for the solution coming from this discussion and the chat. – Tiloine

Ofcource, you can remove javax.persistence.transactionType=JTA and it will work.

But if you want to use JBOSS AS with own transaction manager (i like it more; there is a some bugs in atomicos which has fixed only customer version), you must put:

transactionType=JTA

Into persistance.xml property: 

<property name="hibernate.transaction.jta.platform"
                      value="org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform" />

Into spring-config: 

<tx:jta-transaction-manager/>
<tx:annotation-driven/>

https://blog.hanqunfeng.com/2016/12/21/spring-boot-study-jpa/#more

@Bean(name = "entityManagerFactory")
@DependsOn({"atomikosJtaPlatfom"}) // need to register atomikosJtaPlatfom first
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    System.out.println("entityManagerFactory init");
    LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
    entityManager.setJpaVendorAdapter(jpaVendorAdapter());
    // entity package
    entityManager.setPackagesToScan("com.example.model.ds1");
    entityManager.setJtaDataSource(dataSource());
    Properties properties = new Properties();       
    properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
    properties.put("hibernate.show_sql", "true");
    properties.put("hibernate.format_sql", "true");
    // JTA setting
    properties.put("hibernate.current_session_context_class", "jta");
    properties.put("hibernate.transaction.factory_class", "org.hibernate.engine.transaction.internal.jta.CMTTransactionFactory");
    // here we specify the AtomikosJtaPlatfom we created ourselves
    properties.put("hibernate.transaction.jta.platform","com.example.AtomikosJtaPlatfom");
    entityManager.setJpaProperties(properties);
    return entityManager;
}
