spark 读取resources 配置文

src/main/resources

第一步。首先配置maven的资源选项，比如

第二部：代码（src/main/resources/conf/area.properties）

package kafka.spark.streaming

import java.io.{FileInputStream, InputStream}
import java.net.URL
import java.util.Properties

/**

  */
object Test extends Serializable{

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

    val resource: URL = this.getClass.getClassLoader.getResource("conf/area.properties")
    val in:InputStream = new FileInputStream(resource.getPath)
    val props : Properties = new Properties
    props.load(in)

    //判断传入数据是否存在
     def isExist(key: String): Boolean =
    {
      props.containsKey (key)
    }

    def getData(x:String ): String = {
      if(!isExist(x)){
       return null
      }
      val property: String = props.getProperty (x)
      property
    }
    val property: String = getData("010")

    print(property)
    in.close ()

  }

}
