Spring 集成在类路径中时无法重置指标计数器

Question

在我的 spring-boot 应用程序（类路径中有 spring-集成）中，我无法重置任何指标计数器。它抛出 ClassCastException :

Exception in thread "metricsExecutor-1" org.springframework.messaging.MessageDeliveryException: Failed to handle GenericMessage [payload=delete, headers={timestamp=1435738406974, id=4c9aaac0-8bf1-aac1-d9c9-6f8d50f7801b, metricName=counter.test.toto}] to org.springframework.messaging.support.ExecutorSubscribableChannel$SendTask@2e9f560 in org.springframework.boot.actuate.metrics.writer.MetricWriterMessageHandler@4dec731e; nested exception is java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.boot.actuate.metrics.Metric

    ... 3 more

我认为这是 messageChannel 的错误，有没有办法禁用它？

Answer 1

正在向 MetricWriterMessageHandler 订阅的频道发送带有 String 负载 ("delete") 的消息。它只希望看到 Delta 或 Metric 有效载荷。

如果您打开 DEBUG 日志记录，您应该能够找出是什么向频道发送虚假消息。

如果您确定它是引导代码，请在 GitHub 中打开一个针对引导的问题。
