Question

在我的spring-boot应用程序中（在classpath中使用spring-integration），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

我认为这是messageChannel的一个错误，所以有没有办法禁用它？

Answer 1

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

如果您打开DEBUG日志记录，您应该能够找出将虚假消息发送到频道的内容。

如果您确定它的启动代码，请在GitHub中打开引导问题。

当Spring Integration位于类路径
