【问题描述】：
我有一个使用 JTA + JPA 和 Spring（版本 4）的简单 Web 应用程序。 我正在使用 Atomikos JTA 事务管理器进行 XA 事务。此事务涉及将 EmployeeA 实体插入 DatabaseA 并将另一个 EmployeeB 实体插入另一个 DatabaseB。
奇怪的是，应用程序没有抛出任何错误但没有将输入插入到数据库中。
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");
}
}
服务类实现：
@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 ");
}
}
DAO 实现和接口：
@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;
}
}
