我们正在使用Spring Integration Java DSL，并且间歇性地观察到stackoverflow错误，并且从stack-trace观察到无限循环。但是无法弄清楚为什么它是间歇性发生的，为什么不是总是如此。
我们看到的Stacktrace是：

任何帮助或指针都会有所帮助。
我的集成流程如下：
@Bean
public IntegrationFlow lxxDownstreamNotificationFlow() {
LOGGER.info("Inside the downstream notification flow - lcmDownstreamNotificationFlow()");
return IntegrationFlows.from(lxxDownstreamNotificationChannel)
.handle(lxxNotificationProcessor)
.gateway(requestxxxxxxxEventLogger)
.channel("lxxCoreReplyChannel")
.get();
}
我找不到任何与inputChannel和OutPutChannel相同的流/组件。但是，我们有一些常用的实用程序流程被使用，在某个地方我感觉到这是导致问题的原因。
我前面提到的网关正在路由到下面的集成流程
@Component
public final class EventLoggingFlow implements IntegrationFlow {
private Long eventId;
private String message;
@Autowired
private EventPublishingHandler eventPublishingHandler;
public EventLoggingFlow() {
}
public EventLoggingFlow(Long eventId, String message) {
super();
this.eventId = eventId;
this.message = message;
}
@Override
public void configure(IntegrationFlowDefinition<?> t) {
t .fixedSubscriberChannel()
.enrichHeaders(new Consumer<HeaderEnricherSpec>() {
@Override
public void accept(HeaderEnricherSpec t) {
t.headerExpression(HeaderKeys.SOURCE, "payload.sourceChannel");
}
})
.enrich(new EventEnricherSpec(eventId, message))
.publishSubscribeChannel(eventPublishingHandler)
.handle(new BridgeHandler());
}
}
Publish/Subscribe flow is implemented as below :
@Component
@DependsOn("eventSubcriberFlow")
public class EventPublishingHandler implements Consumer<PublishSubscribeSpec> {
@Autowired
private EventSubcriberFlow eventSubcriberFlow;
@Override
public void accept(PublishSubscribeSpec t) {
t.subscribe(eventSubcriberFlow);
}
}
@Component
public class EventSubcriberFlow implements IntegrationFlow {
@Autowired
private EventSubscribingHandler eventSubscribingHandler;
@Override
public void configure(IntegrationFlowDefinition<?> flow) {
flow.fixedSubscriberChannel()
.handle(eventSubscribingHandler)
.channel("nullChannel");
}
}
fixedSubscriberChannel（）是否引起循环？
答案 0 :(得分：0)
这种行为的典型错误是将输出发送到该通道的流也终止于该通道并再次重新发送消息。很难说在哪里，但是根据堆栈跟踪，有一些调用SOAP服务的东西，您没有显示。
