如何测试Spring集成(How to test Spring Integration)

我是新来的Spring集成。我用的ActiveMQ说“RESPONSEQ”。 > painResponseChannel - - >变压器 - > processResponseChannel - > beanProcessing所以当消息 'RESPONSEQ' 到达。我有以下设置：

    <jms:message-driven-channel-adapter  extract-payload="true"
                                     channel="painResponseChannel"
                                     connection-factory="connectionFactory"
                                     destination-name="responseQ"/>

    <integration:channel id="painResponseChannel" />

    <integration-xml:unmarshalling-transformer
        id="defaultUnmarshaller"
        input-channel="painResponseChannel"
        output-channel="processResponseChannel"
        unmarshaller="marshaller"/>

    <integration:channel id="processResponseChannel" />

    <integration:service-activator
        input-channel="processResponseChannel"
        ref="processResponseActivator"/>

    <bean id="processResponseActivator" class="com.messaging.processor.PainResponseProcessor"/>


    <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
      <property name="classesToBeBound">
        <list>
            <value>com.domain.pain.Document</value>
        </list>
      </property>
    </bean>

所以我的问题是我如何测试这个端到端的？我怎么能断言变压器的输出或断言什么渠道呢？我曾尝试但失败了...希望有人能帮助。

提前致谢。 GM

我测试这样的：在我的测试环境中创建一个出站通道适配器，将发起对使用testJmsQueue通道的ActiveMQ的消息。又创造了processResponseChannel的桥梁 - > testChannel。我期待收到（）方法来给我的东西回来。但我认为这个问题是它过快的时候它到达receive（）方法的管道已经结束。

测试情境是这样的：

<integration:bridge input-channel="processResponseChannel" output-channel="testChannel"/>

<jms:outbound-channel-adapter id="jmsOut" destination-name="responseQ" channel="testJmsQueue"/>

<integration:channel id="testJmsQueue"/>

<integration:channel id="testChannel">
    <integration:queue/>
</integration:channel>

然后在单元测试我有这样的：

@ContextConfiguration(locations = "classpath*:PainResponseTest-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)
public class PainResponseTest {

private String painResponseXML;

@Autowired
MessageChannel testJmsQueue;
@Autowired
QueueChannel testChannel;

@Before
public void setup() throws Exception {

    ClassPathResource cpr = new ClassPathResource("painResponse.xml");
    InputStream is = cpr.getInputStream();
    StringWriter writer = new StringWriter();
    IOUtils.copy(is, writer, "UTF-8");
    painResponseXML = writer.toString();
}

@Test
@SuppressWarnings("unchecked")
public void shouldDoSomething() throws InterruptedException {

    testJmsQueue.send(MessageBuilder.withPayload(painResponseXML).build());

    Message<String> reply = (Message<String>) testChannel.receive(0);
    Assert.assertNotNull("reply should not be null", reply);
    String out = reply.getPayload();
    System.out.println(out);
}
}

==================== TEST OUTPUT =====================
java.lang.AssertionError: reply should not be null

获得回复为空。

对于终端到终端的测试，你可以做以下;
