【问题描述】：
我正在尝试使用 org.apache.commons.configuration2 读取属性文件并在下面出现错误，请让我知道我做错了什么我正在通过给定链接 https://commons.apache.org/proper/commons-configuration/userguide/quick_start.html 寻求帮助
File:- xyz.properties
driver = "oracle.jdbc.driver.OracleDriver"
url = "jdbc:oracle:thin:@xxxx:1521/xxxx.xxxx"
username = "xxx"
password = "xxx"
input_file = "C:\\Users\\xxx\\test\\src\\main\\resources\\xxxx.xlsx"
code:- File.scala
import org.apache.commons.configuration2.builder.fluent.{Configurations}
object Configuration {
def main(args: Array[String]): Unit = {
val config = new Configurations();
val configs = config.properties(new File("xyz.properties"));
val inputFile = configs.getString("input_file")
val userName = configs.getString("username")
val password = configs.getString("password")
val driver = configs.getString("driver")
val url = configs.getString("url")
println("Inside config" + inputFile )
}
}
Error :-

sbt 文件
name := "xxx.xxxx.xxxxx"
scalaVersion := "2.10.6"
ivyScala := ivyScala.value map{ _.copy(overrideScalaVersion = true) }
libraryDependencies ++= Seq("org.apache.spark" %% "spark-core" % "2.1.0",
"com.databricks" %% "spark-csv" % "1.5.0",
"org.apache.commons" % "commons-configuration2" % "2.1.1" )
【问题讨论】：
-
您能否在问题中包含您的 sbt 文件设置（libraryDependencies）。
-
@rogue-one 我已经添加了 sbt 文件，请看上面的更新。
