I am starting my application as follows :

I am getting the following exception on starting my application

回答我自己的问题,

我对我的 pom 做了以下修改

添加了依赖

<dependency>
    <groupId>io.kamon</groupId>
    <artifactId>kamon-autoweave_2.11</artifactId>
    <version>0.6.1</version>
</dependency>

并删除了 kamon-akka-remote-2.4_2.11 jar

将我的 application.conf 更改为

kamon {

  metric {

    # Time interval for collecting all metrics and send the snapshots to all subscribed actors.
    tick-interval = 60 seconds

    disable-aspectj-weaver-missing-error = false

    # Specify if entities that do not match any include/exclude filter should be tracked.
    track-unmatched-entities = yes

    filters {
      akka-actor {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      akka-router {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      akka-dispatcher {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      trace {
        includes = [ "**","ClusterSystem/user/**"]
        excludes = []
      }
    }
  }

  show-aspectj-missing-warning = no
 kamon-log-reporter {
      requires-aspectj = no
      auto-start = yes
    }

}

由于添加了 autoweave jar,我们不需要在启动应用程序时提供 -javaagent 参数。
