Apache TomEE

Exemplo

Este exemplo é uma aplicação de planejamento de reuniões. É um aplicativo JAX-WS e aceita requisições para a reserva de reuniões. A aplicação primeiro verifica se a requisão pode ser reservada, se possivel, ela é reservada e retorna para o cliente se o pedido foi reservado (um valor booleano). Esta é uma aplicação simples, com propósito de demonstração, por isso é bastante simplificado. Uma solicitação de reserva é representada apenas pela data de início da reunião (um valor java.util.Date). Uma solicitação de reserva pode ser reservada se começar após a data atual.

A logica de negócio é implementada usando uma classe MeetingPlannerImpl (implementando` MeetingPlanner`). Esta classe é um serviço JAX-WS, expondo o seguinte método: boolean book (final Date date). O cliente vai enviar uma requisição, contendo uma data; o serviço vai retornar true ou false, se o pedido pode ser reservado. O serviço JAX-WS exposto usa, além disso, uma característica diferente, CDI, injetar uma classe de serviço de lógica de negócios, verificando se a solicitação pode ser reservada. Então, quando chegar a hora de testar a anotação @ ApplicationComposer, verificaremos se o CDI funcionou em nossa aplicação e se o serviço JAX-WS está em execução (ou funcionando).

A lógica de negócios que verifica se uma solicitação é registrável é definida pela seguinte interface:

import java.util.Date;

public interface Agenda {
    boolean isBookable(Date d);
}

A implementação é simples, sem muitos detalhes:

import java.util.Date;

public class LazyAgenda implements Agenda {
    @Override
    public boolean isBookable(final Date d) {
        return d.after(new Date());
    }
}

O serviço JAX-WS é definido pela seguinte interface:

import javax.jws.WebMethod;
import javax.jws.WebService;
import java.util.Date;

@WebService
public interface MeetingPlanner {

    @WebMethod(operationName = "book", exclude = false)
    boolean book(final Date date);
}

A classe que implementa essa interface é:

import javax.inject.Inject;
import javax.jws.WebService;
import java.util.Date;

@WebService
public class MeetingPlannerImpl implements MeetingPlanner {
    @Inject
    private Agenda agenda;

    @Override
    public boolean book(final Date date) {
        return agenda.isBookable(date);
    }
}

Usando o Application Composer

Agora, que a aplicação está completa, é hora de testa-la. Pra isto, iremos adcionar um teste unitário que ira usar o Application Composer para iniciar e fazer deploy da nossa aplicação em um ambiente Java EE Full .

O teste completo:

import org.apache.openejb.jee.WebApp;
import org.apache.openejb.junit.ApplicationComposer;
import org.apache.openejb.testing.Classes;
import org.apache.openejb.testing.Configuration;
import org.apache.openejb.testing.EnableServices;
import org.apache.openejb.testing.Module;
import org.apache.openejb.testng.PropertiesBuilder;
import org.apache.openejb.util.NetworkUtil;
import org.junit.Test;
import org.junit.runner.RunWith;

import javax.xml.bind.JAXBContext;
import javax.xml.namespace.QName;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
import java.net.URL;
import java.util.Date;
import java.util.Properties;

import static org.junit.Assert.assertTrue;

@EnableServices("jax-ws")
@RunWith(ApplicationComposer.class)
public class MeetingPlannerTest {
    private static final int JAX_WS_PORT = NetworkUtil.getNextAvailablePort();

    @Configuration
    public Properties configuration() {
        return new PropertiesBuilder().p("httpejbd.port", Integer.toString(JAX_WS_PORT)).build();
    }

    @Module
    @Classes(cdi = true, value = {MeetingPlannerImpl.class, LazyAgenda.class})
    public WebApp war() {
        return new WebApp()
                .contextRoot("/demo")
                .addServlet("jaxws", MeetingPlannerImpl.class.getName(), "/meeting-planner");
    }

    @Test
    public void bookPort() throws Exception {
        final Service service = Service.create(
                new URL("http://127.0.0.1:" + JAX_WS_PORT + "/demo/meeting-planner?wsdl"),
                new QName("http://jaxws.example.superbiz.org/", "MeetingPlannerImplService"));
        final MeetingPlanner planner = service.getPort(MeetingPlanner.class);
        assertTrue(planner.book(new Date(System.currentTimeMillis() + 1000000)));
    }
}

A primeira coisa que podemos notar é que, nós usamos o Application Composer como executor JUnit. Então, Nosso teste se integra com as ferramentas atuais, assim como qualquer outro teste JUnit. A configuração do teste é definida no método anotado com @ Configuration.

A aplicação é iniciada no método tendo a annotatação @Module . Neste exemplo, especificamos as classes que queremos analisar e o fato de que queremos usar o CDI.

Nosso teste faz um pedido de reserva, enviando uma data no futuro, ele verifica se a reserva está concluída.

Executando o teste

Executando o teste nós podemos ver que a aplicação iniciou com sucesso, que o serviço JAX-WS está em execução e que atende corretamente as solicitações recebidas.
