问题
I got this problem for a while and can't figure out what I am doing wrong. Here is the context:
- Spring 4.3.4.RELEASE
- Spring-data-jpa 1.10.6.RELEASE
- Hibernate 5.2.5.Final
- I'm using wildfly 10, starting via maven plugin
- configured datasource for JNDI lookup correctly
- using spring-data with @Repository on interfaces
- created entityManagerFactory as a spring bean (LocalContainerEntityManagerFactoryBean)
- as for transaction manager, I tried to use both 'tx:jta-transaction-manager' and spring bean (JtaTransactionManager)
- configured persistence.xml
- enable 'tx:annotation-driven'
So, I got a @Service class (SistemaBOImpl) that has a @Repository injected (SistemaDAO) and a test method for transactional behavior:
@Service
@Transactional(propagation = Propagation.SUPPORTS)
public class SistemaBOImpl extends AbstractBO<Sistema, Long> implements SistemaBO {
@Autowired
public SistemaBOImpl(SistemaDAO sistemaDAO) {
super(sistemaDAO);
}
@Override
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = { BusinessException.class })
public void testTrans() throws BusinessException {
try {
final Sistema s = findOne(1L);
s.setCodUsuAlt(SimpleDateFormat.getInstance().format(new Date()));
s.setDatAlt(new Date());
save(s); //1st save
save(new Sistema()); //2nd save
} catch (Exception e) {
throw new RuntimeException(e);
// throw new BusinessException(e);
}
}
}
DAO
@Repository
@Transactional
public interface SistemaDAO extends DAO<Sistema, Long>, JpaRepository<Sistema, Long> {}
The problem is: Although 2nd save won't complete due to database constraints (and I did it on purpose, 1st save is commited and data is changed. I can't figure out why it is not rolling back all. What am I doing wrong?!?
Here are my other config file:

Check if the MySQL engine you are using is InnoDB. If you are using MyISAM, transaction is not supported.

Got it folks!
After debugging for, like, a lot and searching for flaws on transaction configurations, I ended up seeing that all my Business weren't proxies. Well, that said I thought that it should be spring configuring my beans the issue and, for god sake :), was it. I got this spring-mvc config done wrong (WEB-INF/myco-servlet.xml):
<context:component-scan base-package="br.com.myco" />
<mvc:annotation-driven />
See the base-package? It was pointing to the same packages as in my applicationContext.xml:
<context:component-scan base-package="br.com.myco" />
I just had to change that config in myco-servlet.xml to the main mvc package:
<context:component-scan base-package="br.com.myco.service" />
And worked just fine!
Kudos for this question on stackoverflow also for the enlightment about the issue.
