jar 包配置文件读取小工具

实现

final class ConfigUtil
object ConfigUtil {

  def properties(): Properties = props()

  private def props(): Properties = {
    val properties = new Properties()
    val env = sys.props.getOrElse("env", "dev")
    properties.load(classOf[ConfigUtil].getResourceAsStream("/" + env + ".properties"))
    properties
  }

}

多环境区分

resources/dev.properties
resources/pro.properties

运行使用

java -jar demo.jar -Denv=pro
