Question

My problem is simple, I want to rollback all the db changes that were caused by invocation of my service method. I have a problem with correct annotating. I’m not really sure where to put @Transactional and where should I set Propagation to REQUIRES_NEW or MANDATORY. I will paste a code that I wrote, which apart from the fact that SQLException is thrown does not rollback db changes.

The code:

@Service
public class SwapInsertService {

    @Autowired
    MyDao myDao;

    @Transactional(propagation = Propagation.REQURIES_NEW, rollbackFor = SQLException.class)
    public void insertToManyTables(MyData data) throws SQLException {

        insertToSpecificTables(data);
        myDao.insertTwo(data);
    }

    @Transactional(propagation = Propagation.MANDATORY)
    public void insertToSpecificTables(MyData data) throws SQLException {

        myDao.insertOne(data);
    }
}

@Repository
public class MyDaoImpl implements MyDao {

    @Transactional(propagation = Propagation.MANDATORY)
    public void insertOne(MyData data) throws SQLException {

        // INSERT
    }

    @Transactional(propagation = Propagation.MANDATORY)
    public void insertTwo(MyData data) throws SQLException {

        // throws SQLException 
    }
}

Let’s assume insertTwo throws SQLException . I would like to rollback all the previous inserts. What am I doing wrong?

My understanding:

Propagation.REQURIES_NEW creates new transaction.
Propagation.MANDATORY supports current transaction.

insertTwo throws error, insertToManyTables rollbacks everything and voilà. Unfortunately it is not that easy.

EDIT: It’s important to mention that i’m using CGLIB for proxies.

Check whether AUTO_COMMIT is set to false in data source configuration in spring specific xml
