我有以下application.conf并试图找出定义我的课班上最好的方式来加载配置：Pureconfig类型安全配置与层次的根密钥

allKeys { 
    mysql { 
    dev { 
     host = <host1> 
     user = <user1> 
    } 
    prod { 
     host = <host1> 
     user = <user1> 
    } 
    hdfs { 
    endpoint = <host1> 
    port = <port1> 
    } 
} 
my case classes: 
    case class Settings(mysql: DbSettings, hdfs: HdfsSettings) 
    case class DbSettings(host: String, user: String) 
    case class HdfsSettings(endpoint: String, port: String)

我在遇到问题的认识如何正确加载，以便它在hdfs中查找类似的键时不会失败。

回答：

您需要定义您的案例类以适应配置结构。

case class HdfsConfig(endpoint: String, port: Int) 
case class DbConfig(host: String, user: String) 
case class MySqlConfig(dev: DbConfig, prod: DbConfig) 
case class AllConfigs(mysql: MySqlConfig, hdfs: HdfsConfig) 
case class MyConfig(allKeys: AllConfigs)

现在你可以阅读这些作为，
