java - 找不到 kamon play 应用程序的 application.conf 资源

Question

我尝试使用 Kamon.io 监控的 play-akka 应用程序在这里遇到了一些问题。我在告诉我我没有使用 kamon.start() 并且在 Runtime 中找到有关 javaOptions 的工作后遇到了麻烦：= Seq("-Dkamon.auto-start=true"); 我现在发现自己的 application.conf 文件出现资源未找到错误。

当我不运行 aspectjweaver 时，kamon 会抛出一个不同的错误，但我的应用程序会工作。这是我遇到的错误，如果有人可以提供帮助，它将极大地帮助我！多谢你们！

对于 Play 2.5 和 Kamon 0.6.2，以下方法有效。您需要application.conf通过系统属性传递路径，如下所示：

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

尊重路径很重要。在上面的示例中，在我当前的项目中，Play 应用程序是多项目 SBT 构建中的项目，因此位于名为“webapp”的子目录中。如果您正在运行一个简单的单一项目构建，您可以这样称呼它：

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

我遇到了类似的问题，最后发现我没有为 Akka 提供网络上下文。在控制器中，您必须确保在调用与 Web 相关的方法时传递上下文。以下是一个java示例：

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

如果没有 Web 上下文，就无法找到任何文件。

看来这个问题在下一个 kamon 版本（v.0.6.0）中得到了解决。

不过有一个解决方法。我在这里找到它： https ://groups.google.com/forum/#!msg/kamon-user/b9U7Z7EfQcM/7vQuHAKxDwAJ

将“我”添加到列表中。它以某种方式改变了 Play 定位某些事物的方式。
