用scala向es寫數據

      """
        |{

    //fuc2
    val source = User("java", 13)
    //向es寫數據
    val action = new Index.Builder(source)
      .index("javademo")
      .`type`("test")
      .id("2")
      .build()
    client.execute(action)

  }
}

case class User(name: String, age: Int)

注意

scala中type是關鍵字，所以在demo中需要用到反引號來避免歧義！
