Question

一段时间以来，我一直在挠头。我的错误在我的JSON后面的端点中传播。

对于每个请求，原始JSON都会在此消息的末尾附带该消息：

[{"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，用于用prometheus进行监视...我在另一个项目中使用了此模板，但它没有给我带来任何问题。我不确定发生了什么变化。

老实说，我不知道该怎么做才能调试这类东西...

这是部分堆栈跟踪（很长，可以根据要求包含整个内容）。 [http-nio-8080-exec-2] default 2018-06-21 12:40:31,634 ERROR o.a.c.c.C.[.[.[.[dispatcherServlet]:182 - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Filter execution threw an exception] with root cause java.lang.NoSuchMethodError: io.micrometer.core.instrument.AbstractTimer.(Lio/micrometer/core/instrument/Meter$Id;Lio/micrometer/core/instrument/Clock;Lio/micrometer/core/instrument/distribution/DistributionStatisticConfig;Lio/micrometer/core/instrument/distribution/pause/PauseDetector;Ljava/util/concurrent/TimeUnit;Z)V at io.micrometer.prometheus.PrometheusTimer.(PrometheusTimer.java:40) at io.micrometer.prometheus.PrometheusMeterRegistry.newTimer(PrometheusMeterRegistry.java:161) at io.micrometer.core.instrument.MeterRegistry.lambda$timer$2(MeterRegistry.java:255) at io.micrometer.core.instrument.MeterRegistry.getOrCreateMeter(MeterRegistry.java:561) at io.micrometer.core.instrument.MeterRegistry.registerMeterIfNecessary(MeterRegistry.java:537) at io.micrometer.core.instrument.MeterRegistry.timer(MeterRegistry.java:253) at io.micrometer.core.instrument.Timer$Builder.register(Timer.java:420) at org.springframework.boot.actuate.metrics.web.servlet.WebMvcMetricsFilter.stop(WebMvcMetricsFilter.java:237) at org.springframework.boot.actuate.metrics.web.servlet.WebMvcMetricsFilter.record(WebMvcMetricsFilter.java:228) at org.springframework.boot.actuate.metrics.web.servlet.WebMvcMetricsFilter.filterAndRecordMetrics(WebMvcMetricsFilter.java:166) at org.springframework.boot.actuate.metrics.web.servlet.WebMvcMetricsFilter.filterAndRecordMetrics(WebMvcMetricsFilter.java:126) at org.springframework.boot.actuate.metrics.web.servlet.WebMvcMetricsFilter.doFilterInternal(WebMvcMetricsFilter.java:111) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)

Answer 1

我不知道这是怎么改变的，但是我注意到我的配套服务使用的是spring.2.boot-starter-actuator的2.0.2.RELEASE和micrometer-registry-prometheus的1.0.4。

我更改了pom使其与这些版本匹配，该问题消失了。

虚惊一场，对不起！
