说,在一个动作中我有:
val linesEnu = {
val is = new java.io.FileInputStream(path)
val isr = new java.io.InputStreamReader(is, "UTF-8")
val br = new java.io.BufferedReader(isr)
import scala.collection.JavaConversions._
val rows: scala.collection.Iterator[String] = br.lines.iterator
Enumerator.enumerate(rows)
}
Ok.feed(linesEnu).as(HTML)
如何关闭读者/流?
