Spring Integration poller有时会运行一次然后停止(Spring Integration poller sometimes runs once then stops)

 我在Spring Integration应用程序中有以下基于注释的配置： 
 

@Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata defaultPoller(@Value("${poll-interval}") int pollInterval) {
    return Pollers.fixedRate(pollInterval).maxMessagesPerPoll(1).get();
}

@Bean
@InboundChannelAdapter(value = "httpRequestChannel", poller = @Poller(PollerMetadata.DEFAULT_POLLER),
    autoStartup = "${auto-start:true}")
public MessageSource<String> httpRequestTrigger() {
    Expression expression = new SpelExpressionParser().parseExpression(
        "#{@timeService.getLastQueryTime()}",
        new TemplateParserContext("#{", "}"));
    return new ExpressionEvaluatingMessageSource<>(expression, String.class);
}

@Bean
@Qualifier("httpRequestChannel")
public MessageChannel httpRequestChannel() {
    return new RendezvousChannel();
}

@Bean
@ServiceActivator(inputChannel = "httpRequestChannel", poller = @Poller(fixedRate="100"))
public MessageHandler httpRequestExecutingMessageHandler(
    URI backendURI,
    @Qualifier("httpReplyChannel") MessageChannel httpReplyChannel,
    RestTemplate restTemplate,
    @Qualifier("filterExpression") Expression filterExpression
) {
    HttpRequestExecutingMessageHandler messageHandler = new HttpRequestExecutingMessageHandler(
        backendURI.toString() + "?filter={filter}", restTemplate);
    messageHandler.setHttpMethod(HttpMethod.GET);
    messageHandler.setExpectedResponseType(String.class);
    messageHandler.setOutputChannel(httpReplyChannel);
    messageHandler.setExpectReply(true);
    messageHandler.setSendTimeout(1000);
    Map<String, Expression> uriVariableExpressions = new HashMap<>();
    uriVariableExpressions.put("filter", filterExpression);
    messageHandler.setUriVariableExpressions(uriVariableExpressions);
    return messageHandler;
}

@Bean
@Qualifier("httpReplyChannel")
public MessageChannel httpReplyChannel() {
    return new DirectChannel();
}

 

 在我的application.properties文件中， auto-start设置为true ， poll-interval设置为2000。 
 

 有时在启动应用程序时，轮询器将按预期工作，触发每个poll-interval毫秒。 然而，就像往常一样，在启动时，轮询器将会触发一次并且永远不会再次触发。 我的配置有错误吗？ 如何让轮询器始终如一地工作？ 
 

 编辑：当轮询器被绞死时，我接受了一个线程转储：

I have the following annotation-based configuration in a Spring Integration app:
 

@Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata defaultPoller(@Value("${poll-interval}") int pollInterval) {
    return Pollers.fixedRate(pollInterval).maxMessagesPerPoll(1).get();
}

@Bean
@InboundChannelAdapter(value = "httpRequestChannel", poller = @Poller(PollerMetadata.DEFAULT_POLLER),
    autoStartup = "${auto-start:true}")
public MessageSource<String> httpRequestTrigger() {
    Expression expression = new SpelExpressionParser().parseExpression(
        "#{@timeService.getLastQueryTime()}",
        new TemplateParserContext("#{", "}"));
    return new ExpressionEvaluatingMessageSource<>(expression, String.class);
}

@Bean
@Qualifier("httpRequestChannel")
public MessageChannel httpRequestChannel() {
    return new RendezvousChannel();
}

@Bean
@ServiceActivator(inputChannel = "httpRequestChannel", poller = @Poller(fixedRate="100"))
public MessageHandler httpRequestExecutingMessageHandler(
    URI backendURI,
    @Qualifier("httpReplyChannel") MessageChannel httpReplyChannel,
    RestTemplate restTemplate,
    @Qualifier("filterExpression") Expression filterExpression
) {
    HttpRequestExecutingMessageHandler messageHandler = new HttpRequestExecutingMessageHandler(
        backendURI.toString() + "?filter={filter}", restTemplate);
    messageHandler.setHttpMethod(HttpMethod.GET);
    messageHandler.setExpectedResponseType(String.class);
    messageHandler.setOutputChannel(httpReplyChannel);
    messageHandler.setExpectReply(true);
    messageHandler.setSendTimeout(1000);
    Map<String, Expression> uriVariableExpressions = new HashMap<>();
    uriVariableExpressions.put("filter", filterExpression);
    messageHandler.setUriVariableExpressions(uriVariableExpressions);
    return messageHandler;
}

@Bean
@Qualifier("httpReplyChannel")
public MessageChannel httpReplyChannel() {
    return new DirectChannel();
}

 

In my application.properties file, auto-start is set to true and poll-interval is set to 2000.
 

Sometimes when starting up the application, the poller will work as expected, firing every poll-interval milliseconds. However, just as often, when starting up, the poller will fire once and never fire again. Is there an error in my configuration? How do I get the poller to consistently work?
 

EDIT: I took a thread dump when the poller hanged:

最满意答案

 设置缓存标头将产生类似的性能AFAIK。 GAE和GCS都使用Google Edge缓存 。 
 

 GCS可能更容易管理您的静态资源，而需要重新部署到GAE来添加/删除静态资源。 
 

 其他重要说明：GCS as CDN无法通过HTTPS与自定义域一起使用。 GAE确实支持使用自定义域的HTTPS。 

Setting your cache headers will result in similar performance AFAIK. Both GAE and GCS use Google Edge cache.
 

GCS is probably easier to manage your static resources, whereas it takes a redeploy to GAE to add/remove static resources.
 

Other important note : GCS as CDN does not work over HTTPS with custom domains. GAE does support HTTPS with custom domains.
