Scala不使用-Dconfig.file选项加载配置文件

Question

我使用scala、akka、maven和Intellij创建了简单的应用程序，并创建了我的应用程序的胖jar，我尝试使用以下命令运行jar

java -Dconfig.file=/home/pqr-xvcx-xcvxv-sdf/application.conf -jar bac-pqr.jar -Dconfig.trace=loads

在通过命令提示符运行jar时，我遇到以下错误：

Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'bac-pqr'
        at com.typesafe.config.impl.SimpleConfig.findKeyOrNull(SimpleConfig.java:152)
        at com.typesafe.config.impl.SimpleConfig.findKey(SimpleConfig.java:145)
        at com.typesafe.config.impl.SimpleConfig.findOrNull(SimpleConfig.java:172)

        at com.typesafe.config.impl.SimpleConfig.find(SimpleConfig.java:189)
        at com.typesafe.config.impl.SimpleConfig.getString(SimpleConfig.java:246)

        at .config.Settings$.ClusterName(Settings.scala:37)
        at Main$.main(Main.scala:76)
        at .Main.main(Main.scala)

即使在提供了配置文件之后，我也不知道为什么它会抛出这样的exception.Please，在我完整的application.conf文件下面找到：

  kafka {
    bac-pqr-topic = [${?bac-pqr_TOPIC}, "Test"]

    seed-host = ${?SEED_HOST}

    seed-nodes = [

  }

  maxFailures = [${?CBREAKER_MAX_FAILURES}, 10]
  callTimeout = [${?CBREAKER_MAX_FAILURES}, 10000]
  resetTimeout = [${?CBREAKER_MAX_FAILURES}, 30000]
}``

我的胖罐子里没有任何文件。我想将conf文件提供给外部jar。

改变你们论点的顺序。-jar file.jar后的参数是用于程序的主要方法，而不是jvm。

 java -Dconfig.file=/home/hdp66-ss-mods-uk/AEM-Sprint0/ResourceBundle.old/lib/application.conf -Dconfig.trace=loads -jar exception-management.jar
