Question

我实际上是在尝试将Kamon 0.4.0与我的play（scala）应用程序集成在一起（顺便提一下很棒的框架！）。

这是我做的：

在我的 build.sbt 中添加了以下依赖项：

libraryDependencies ++= Seq(
      jdbc,
      anorm,
      "com.typesafe.play" %% "play-mailer" % "2.4.0",
      "org.bouncycastle" % "bcpkix-jdk15on" % "1.51",
      "org.bouncycastle" % "bcprov-jdk15on" % "1.51",
      "com.github.nscala-time" %% "nscala-time" % "1.8.0",
      "io.kamon"    %% "kamon-core"           % "0.4.0",
      "io.kamon"    %% "kamon-play"           % "0.4.0",
      "org.aspectj" % "aspectjweaver"         % "1.8.6"
    )

在Global.scala中启动和关闭Kamon：

object Global extends GlobalSettings {

  override def onStart(app: Application) {
    val hsmProxyName = Play.current.configuration.getString("ngocspd.hsm.proxy.name").get
    val supervisorName = Play.current.configuration.getString("ngocspd.ocspd.supervisor.name").get
    val notifierName = Play.current.configuration.getString("ngocspd.notification.name").get
    java.security.Security.addProvider(new BouncyCastleProvider)
    // Starting Kamon
    Kamon.start()
    Akka.system.actorOf(Props[NotificationActor], name = notifierName)
    Akka.system.actorOf(Props[HardwareSecurityModuleProxyActor], name = hsmProxyName)
    Akka.system.actorOf(Props[OCSPdActor], name = supervisorName)
  }

  override def onStop(app: Application) {
    Kamon.shutdown()
  }
}

使用AspectJ代理的路径启动激活器：

activator -J-javaagent:/Users/pantin/.ivy2/cache/org.aspectj/aspectjweaver/jars/aspectjweaver-1.8.6.jar

我遇到两个问题。

运行应用程序时，会抛出以下异常：

Answer 1

https://groups.google.com/forum/#!topic/kamon-user/Wz1hVypO15E的回复很有帮助。

而不是使用激活器运行以在开发模式下运行播放应用程序，运行sbt阶段后我使用

target/universal/stage/bin/my-app -J-javaagent:fullPathToAspectJ/aspectjweaver-1.8.5.jar

请注意，使用激活器启动不起作用。

Answer 2

有一个允许在sbt中执行LTW的sbt插件，我们将能够无缝地在开发模式下运行。 sbt-aspectj-runner

播放2.3.8 - 无法启动Kamon 0.4.0
