我是 Spring 集成的新手。我有 ActiveMQ 说一个'responseQ'。因此，当消息到达'responseQ' -> painResponseChannel -> 转换器 -> processResponseChannel -> beanProcessing 时。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>
所以我的问题是我怎样才能端到端地测试这个？如何断言变压器的输出或断言通道上的内容？我试过但失败了......希望有人能帮忙。

我是这样测试的：在我的测试上下文中创建了一个出站通道适配器，它启动使用 testJmsQueue 通道在 activeMQ 上放置消息。并且还为 processResponseChannel -> testChannel 创建了一个 BRIDGE。我期待 receive() 方法能给我一些回报。但我认为问题在于它太快了，当它到达 receive() 方法时，管道已经结束。
测试上下文如下所示：
<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>
然后在单元测试中我有这个：
@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
得到回复为空。
