在 Spring Cloud Stream 中使用 @ServiceActivator 時啟動應用程序出錯

Question

我把@ServiceActivator 用來記錄所有給kafka 出錯的消息：

@ServiceActivator(inputChannel = "errorChannel")
public void handleErrors(final ErrorMessage in) {
    log.error("encountered exception" + em.toString());
}

而且我還將errorChannelEnabled標志設置為true：

  cloud:
    stream:
      function:
        definition: consumeProfile
      bindings:
        #kafka producer
        produceProfile-out-0:
          binder: kafka
          destination: profile
          producer:
            use-native-encoding: true
            error-channel-enabled: true

問題是當我上傳應用程序時，我收到了這個錯誤日志：

我的應用程序沒有因為這個異常而崩潰，但我希望你能幫助理解原因，謝謝

Answer 1

謝謝你的樣品。

這是IntegrationMBeanExporter中的一個錯誤：我們嘗試在MessagingAnnotationPostProcessor創建端點 bean 時對其進行拉取。

所以，請在 Spring Integration 項目中提出一個 GH 問題，我們將看看我們能做些什么。

同時，作為一種解決方法，您可以通過相應的 Srping Boot 屬性關閉 JMX： spring.jmx.enabled=false 。 無論 Spring Boot 默認決定如何，我們都會默認為 Spring Integration 自動配置它：

@ConditionalOnProperty(prefix = "spring.jmx", name = "enabled", havingValue = "true", matchIfMissing = true)
protected static class IntegrationJmxConfiguration {
