scala - Config类

第一步：在resources中添加application.conf

host{
  ip = "127.0.0.1"
  port = 2282
}

第二步：在项目目录下创建conf/resources/application.conf

host{
  ip = "127.0.0.1"
  port = 2282
}

第三步：导入依赖

        <dependency>
            <groupId>com.typesafe</groupId>
            <artifactId>config</artifactId>
            <version>1.3.2</version>
        </dependency>

第四步：API操作

import java.io.File

import com.typesafe.config.{Config, ConfigFactory}

object ConfigUtil {
  def main(args: Array[String]): Unit = {

    //ConfigFactory.load()会加载配置文件，默认加载classpath下的application.conf,application.json
    //和application.properties文件。当然也可以调用ConfigFactory.load(confFileName)加载指定的配置文件。
    val config_1: Config = ConfigFactory.load()
    val serverConf: Config = config_1.getConfig("host")
    val ip: String = serverConf.getString("ip")
    val post: Int = serverConf.getInt("port")
    println(ip)
    println(post)

    println("---------------------------------")
    val config_2: Config = ConfigFactory.parseFile(new File("conf/resources/application.conf"))
    val serverConf_2= config_2.getConfig("host")
    val ip_2: String = serverConf.getString("ip")
    val post_2: Int = serverConf.getInt("port")
    println(ip_2)
    println(post_2)
  }
}
