我有一些问题。

我试图介绍akka-http。但我从来没有用 scala 开发过，所以我用 akka-http 来做 java。

当我完成编程时，我想在产品的 Apache Daemon 上运行 akka-http 应用程序。

我尝试在 linux 上的应用程序上运行，并使用 maven 包。但也有一些问题。

我在 Daemon.out 中发现了以下消息

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

这是 Daemon.sh

    #-debug \
    exit $?
    ;;

  stop)

    $MAIN_CLASS
    exit $?
    ;;

  *)
    echo "[Usage] TestDaemon.sh start | stop"
    exit 1;;
esac

我的问题是什么？我尝试了很多事情，但我失败了。

谢谢你。
