com.typesafe.config.ConfigException$Missing：reference.conf：未找到键 'default' 的配置设置

Question

我创建了我的 Akka 应用程序的 jar 文件。当我通过命令运行 jar 文件时

java -jar file.jar

然后我看到这个错误。可能出了什么问题，我该如何解决？

当应用程序无法在类路径中找到 reference.conf 配置文件时，会发生这种错误。

确保您构建的 jar 中存在此类文件。

com.typesafe.config.ConfigException$Missing: reference.conf: No configuration setting found for key 'default'

java

configuration

scala
