【问题描述】：
我在这个问题上摸不着头脑已经有一段时间了。我的 JSON 后面的端点流出了这个错误。
对于每个请求，原始 JSON 都会在其末尾包含此消息：
[{"xd":"0"}]{"error":"OK","message":"io.micrometer.core.instrument.AbstractTimer.<init>(Lio/micrometer/core/instrument/Meter$Id;Lio/micrometer/core/instrument/Clock;Lio/micrometer/core/instrument/distribution/DistributionStatisticConfig;Lio/micrometer/core/instrument/distribution/pause/PauseDetector;Ljava/util/concurrent/TimeUnit;Z)V","path":"/avgSpeed","status":200,"timestamp":"2018-06-21T16:40:31.639+0000"}
我有一个 springboot 应用程序设置，用于使用 prometheus 进行监控...我在另一个项目中使用了这个模板，它没有给我任何问题。我不确定发生了什么变化。
我真的不知道如何调试这种类型的东西......
这是部分堆栈跟踪（它很长，可以根据要求包含整个内容）。

【问题讨论】：
-
您是否包含 micrometer-core？
-
我没有。但不知何故，它通过版本更改自行解决了。
