У меня есть простое веб-приложение, использующее JTA + JPA вместе с Spring (версия 4). Я делаю транзакцию XA с помощью диспетчера транзакций Atomikos JTA. Эта транзакция включает в себя включение объекта EmployeeA в DatabaseA и другой объект EmployeeB в другой DatabaseB.Как вставить в базу данных при использовании JTA + JPA с пружиной
Странно, приложение не вызывает никаких ошибок , но никакие энтеи не вставляются в Базы данных.
public class JtaTest {
public static void main(String[] args) {
JtaTest test = new JtaTest();
test.testMandatory();
}
private static void testMandatory() {
final SpringContextUtil util = SpringContextUtil.instance();
ApplicationContext ctx = util.getApplicationContext();
final JtaEmployeeService employeeService = (JtaEmployeeService)ctx.getBean("jtaEmployeeService");
EmployeeA a = new EmployeeA();
a.setName("emp-a-1");
a.setAge(30);
EmployeeB b = new EmployeeB();
a.setName("emp-b-1");
a.setAge(31);
try {
employeeService.persistEmployees(a, b);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("success");
}
}
Реализация класса обслуживания:
@Service("jtaEmployeeService")
public class JtaEmployeeServiceImpl implements JtaEmployeeService {
@Autowired
@Qualifier("employeea")
private GenericDao<Integer, EmployeeA> employeeADao;
@Autowired
@Qualifier("employeeb")
private GenericDao<Integer, EmployeeB> employeeBDao;
@Override
@Transactional(propagation=Propagation.REQUIRED, readOnly=false, isolation=Isolation.DEFAULT, rollbackFor=Exception.class)
public void persistEmployees(EmployeeA employeeA, EmployeeB employeeB) throws Exception {
employeeADao.save(employeeA);
employeeBDao.save(employeeB);
System.out.println("Saving employee A and employee B ");
}
}
Реализация DAO и интерфейсы:
@Repository("employeeb")
public class EmployeeBDaoImpl extends AbstractJTADaoDatabaseB implements
GenericDao<Integer, EmployeeB> {
@Override
public void save(EmployeeB entity) {
super.persist(entity);
}
}
@Repository("employeea")
public class EmployeeADaoImpl extends AbstractJTADaoDatabaseA implements
GenericDao<Integer, EmployeeA> {
@Override
public void save(EmployeeA entity) {
super.persist(entity);
}
}
public abstract class AbstractJTADaoDatabaseB {
@PersistenceContext(unitName = "persistenceUnitB")
@Qualifier("myManager")
private EntityManager entityManager;
public void persist(Object entity) {
entityManager.persist(entity);
// entityManager.flush();
}
protected EntityManager getEntityManager() {
return entityManager;
}
}
public abstract class AbstractJTADaoDatabaseA {
@PersistenceContext(unitName = "persistenceUnitA")
@Qualifier("myManager")
private EntityManager entityManager;
public void persist(Object entity) {
entityManager.persist(entity);
// entityManager.flush();
}
protected EntityManager getEntityManager() {
return entityManager;
}
}
