scala - 如何知道，如果配置已加载

Question

我正在使用 akka http websocket client并希望让客户保持活力。
在 Automatic keep-alive Ping support 部分，它说，将配置放入 application.conf 如下:

akka.http.client.websocket.periodic-keep-alive-mode = pong

我已经这样做了:

akka.http {
  websocket {
    # periodic keep alive may be implemented using by sending Ping frames
    # upon which the other side is expected to reply with a Pong frame,
    # or by sending a Pong frame, which serves as unidirectional heartbeat.
    # Valid values:
    #   ping - default, for bi-directional ping/pong keep-alive heartbeating
    #   pong - for uni-directional pong keep-alive heartbeating
    #
    # See https://tools.ietf.org/html/rfc6455#section-5.5.2
    # and https://tools.ietf.org/html/rfc6455#section-5.5.3 for more information
    periodic-keep-alive-mode = ping

    # Interval for sending periodic keep-alives
    # The frame sent will be the onne configured in akka.http.server.websocket.periodic-keep-alive-mode
    # `infinite` by default, or a duration that is the max idle interval after which an keep-alive frame should be sent
    periodic-keep-alive-max-idle = infinite
  }
} 

如何确定配置是否被采用？

我不确定我是否真的理解您的问题，但是您可以通过设置 akka.log-config-on-start 在加载 Actor 系统时显示完整的配置(包括覆盖等)。到。
