我正在尝试测试流程,特别是在引发异常时,但由于某种原因,我在 errorsFromSend 中没有得到任何东西。 channel 。

这里是网关:

@MessagingGateway
public interface Send
{
@Gateway(requestChannel = "sending",
headers = @GatewayHeader(name = "errorChannel", expression = "@errorsFromSend"))
void send(final String s);
}

input = "xyz" 引发异常的转换器:
public class Transformer {
public String transform(final String s) {
if(s.equals("xyz")) {
throw new RuntimeException("xyz");
}
log.debug(s);

return s;
}

private final Logger log = LoggerFactory.getLogger(this.getClass().getName());
}

这是带有上下文的测试:
@RunWith(SpringRunner.class)
@EnableIntegration
@ComponentScan(basePackageClasses= {sample.Send.class})
@ContextConfiguration(classes = {SendWithFlowTestConfiguration.class})
public class SendWithFlowTest {
@Test
public void testReceiving() throws Exception {
// arrange
final String payload1 = "123";
final String payload2 = "ABC";
final String payload3 = "xyz";
// act and assert
send.send(payload3);
send.send(payload1);
send.send(payload2);

Message<?> fromErrorsFromSend = errorsFromSend.receive(100); // returns null!
Assertions.assertThat(fromErrorsFromSend.getPayload()).isEqualTo(payload3);
fromErrorsFromSend = errorsFromSend.receive(0);
Assertions.assertThat(fromErrorsFromSend).isEqualTo(null);
// verify
}

@Autowired
private QueueChannel errorsFromSend;

@Autowired
private Send send;
}

@Configuration
@EnableIntegration
@IntegrationComponentScan
class SendWithFlowTestConfiguration {
@Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata poller() {
return Pollers.fixedRate(1)
.maxMessagesPerPoll(1)
.get();
}

@Bean
public DirectChannel receiving() {
return new DirectChannel();
}

@Bean
public QueueChannel sending() {
return new QueueChannel();
}

@Bean
public QueueChannel errorsFromSend() {
return new QueueChannel();
}

@Bean
public Transformer transformer() {
return new Transformer();
}

@Bean
@Value("2")
public TaskExecutor executor(final int poolSize) {
return new TaskExecutorAdapter(Executors.newFixedThreadPool(poolSize));
}

@Bean
public IntegrationFlow flow(@Qualifier("executor") final TaskExecutor executor) {
return IntegrationFlows.from(sending())
.channel(MessageChannels.executor("receiving", executor).get())
.transform(transformer())
.handle(m -> System.out.println(">> " + m.getPayload()))
.get();
}
}

谁能告诉我为什么 errorsFromSend channel 没有得到异常?根据 Gary 的建议,这是修剪后的日志:

最佳答案

Caused by: org.springframework.messaging.MessageHandlingException: nested exception is java.lang.RuntimeException: xyz, failedMessage=GenericMessage [payload=xyz, headers={errorChannel=errorsFromSend, id=38b35bcb-61f1-7be4-c523-499d8fa13db7, timestamp=1544808482872}]



由于失败的消息有错误 channel 头;它应该由轮询器中的错误处理程序正确路由。

如果您可以发布完整的项目(可能在 Gist 中,或者完整的项目在 GitHub 中),我们可以看看。

编辑

看起来 DSL 有一个错误,执行程序 channel 未正确初始化,因此您的任务执行程序未包含在 ErrorHandlingTaskExecutor 中.

这是一个解决方法:
  @Bean
public IntegrationFlow flow(@Qualifier("executor") final TaskExecutor executor)
{
return IntegrationFlows.from(sending())
.channel(execChannel(executor))
.transform(transformer())
.handle(m -> System.out.println(">> " + m.getPayload()))
.get();
}

@Bean
public ExecutorChannel execChannel(final TaskExecutor executor) {
return MessageChannels.executor("receiving", executor).get();
}

(将 channel 定义为 @Bean )。

或者,只需制作 sending()一个执行者 channel 开始。

编辑2

实际上,这并不是一个真正的基本错误。您有 2 个名为 receiving 的 channel 这使 DSL 感到困惑,因为它发现了一个具有该名称的现有 bean,因此没有初始化 Executor channel 。
