Я пытаюсь проверить EJB, в который вставлен еще один.
Для целей тестирования я хочу использовать заглушку для введенного EJB. Я использовал openEJB в качестве основы для EJB для тестирования.
Вот EJB:
@Stateless
@Local(IService.class)
public class Service implements IService {
@EJB
private IBean bean;
@Override
public String doService(String data) {
return bean.process(data);
}
}
Реальный введенный EJB:
@Stateless
@Local(IBean.class)
public class Bean implements IBean {
private static Logger logger = Logger.getLogger(Bean.class);
@Override
public String process(String data) {
logger.info("Bean processing : " + data);
return "Bean processing : " + data;
}
}
Версия-заглушка EJB:
@Stateless
@Local(IBean.class)
public class BeanStub implements IBean {
private static Logger logger = Logger.getLogger(BeanStub.class);
@Override
public String process(String data) {
logger.info("Stub processing : " + data);
return "Stub processing : " + data;
}
}
И используемый тест JUnit:
public class ServiceTest {
private static Logger logger = Logger.getLogger(ServiceTest.class);
private static InitialContext context;
@BeforeClass
public static void setUpBeforeClass() throws Exception {
// openEJB
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.apache.openejb.client.LocalInitialContextFactory");
p.put("openejb.altdd.prefix", "stub"); // use specific ejb-jar
p.put("openejb.descriptors.output", "true");
context = new InitialContext(p);
}
@Test
public void testServiceStub() {
try {
IService service = (IService) context.lookup("ServiceStubLocal");
assertNotNull(service);
String msg = service.doService("service");
assertEquals("Stub processing : service", msg);
} catch (NamingException e) {
logger.error(e);
fail(e.getMessage());
}
}
}
Я пытался переопределить использование реального EJB заглушкой, используя определенный ejb-jar (я хочу использовать «BeanStub» вместо «Bean» по умолчанию в моем сервисе):
<ejb-jar>
<enterprise-beans>
<session id="ServiceStub">
<ejb-name>ServiceStub</ejb-name>
<ejb-class>tests.Service</ejb-class>
<ejb-local-ref>
<ejb-ref-name>tests.Service/bean</ejb-ref-name>
<ejb-link>BeanStub</ejb-link>
</ejb-local-ref>
</session>
</enterprise-beans>
</ejb-jar>
К сожалению, у меня возникла проблема с объявлением EJB:

Что-то не так в подходе или в способе написать ejb-jar?
