未找到kamon play應用程序的application.conf資源

Question

在我嘗試使用Kamon.io監視我的play-akka應用程序時遇到了一些麻煩。我遇到了麻煩，告訴我我沒有使用kamon.start（），並在運行時找到javaOptions的工作後：= Seq（「 - Dkamon.auto-start = true」）;我現在發現自己的資源未找到我的application.conf文件錯誤。

當我不運行aspectjweaver卡蒙拋出一個不同的錯誤，但我的應用程序將工作。這是我得到的錯誤，如果有人能幫助它，那將大大幫助我！多謝你們！

Answer 1

添加「我到」列表。它以某種方式改變了Play如何定位特定事物的方式。

Answer 2

看來這個問題在下一個kamon版本（v.0.6.0）中得到解決。

雖然有一個解決方法。我在這裏找到它： https://groups.google.com/forum/#!msg/kamon-user/b9U7Z7EfQcM/7vQuHAKxDwAJ

Answer 3

對於Play 2.5和Kamon 0.6.2，以下方法有效。你需要通過系統屬性傳遞application.conf路徑，像這樣：

sbt "webapp/aspectj-runner:run" -Dconfig.file=webapp/conf/application.conf 

要尊重的路徑是非常重要的。在上面的示例中，從我當前的項目中，Play應用程序是多項目SBT構建中的項目，因此駐留在名爲「webapp」的子目錄中。如果你正在運行一個簡單的燒毛，項目生成，你會這樣稱呼它：

sbt "aspectj-runner:run" -Dconfig.file=conf/application.conf 

Answer 4

我也有類似的問題，在我沒有提供阿卡與Web上下文最終發現了。 在控制器中，您必須確保在調用Web相關方法時傳遞上下文。以下是一個java示例：

CompletableFuture.supplyAsync(() -> { 
}, MyHttpExecutionContext.current()); 

沒有Web上下文，找不到文件。
