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，但我的应用程序会运行。这是我遇到的错误，如果有人可以提供帮助，那将大大帮助我！谢谢大家！

Answer 1

在列表中添加“我”。它以某种方式改变了 Play 定位某些事物的方式。

Answer 2

这个问题似乎在下一个 kamon 版本 (v.0.6.0) 中得到解决。

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

Answer 3

对于 Play 2.5 和 Kamon 0.6.2，以下方法有效。您需要通过系统属性传递application.conf 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

Answer 4

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。下面是一个java例子：

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

没有 Web 上下文，无法找到任何文件。
