scala - com.typesafe.config.ConfigException$NotResolved : has not been resolved,

Question

我正在尝试使用类型安全配置读取以下配置文件

common = {
  jdbcDriver = "com.mysql.jdbc.Driver"
  slickDriver = "slick.driver.MySQLDriver"
  port = 3306
  db = "foo"
  user = "bar"
  password = "baz"
}

source = ${common} {server = "remoteserver"}
target = ${common} {server = "localserver"}

当我尝试使用此代码读取我的配置时

val conf = ConfigFactory.parseFile(new File("src/main/resources/application.conf"))
val username = conf.getString("source.user")

我收到错误

com.typesafe.config.ConfigException$NotResolved: source.user has not been resolved, you need to call Config#resolve(), see API docs for Config#resolve()

如果我将所有内容都放在“源”或“目标”标签中，我不会收到任何错误。仅当我尝试使用“common”时才会出现错误

Answer 1

我自己解决了。

ConfigFactory.parseFile(new File("src/main/resources/application.conf")).resolve()
