Scala Lift-运行系统命令并等待完成

我当前使用的类位于以下位置：

一切都很好，但我需要代码等待命令完成，然后返回true/false类型响应，这样我就可以继续处理结果

我将它与OpenOffice结合使用来转换一些文档，因此在使用生成的文件之前等待文档转换完成是至关重要的

感谢您的帮助，非常感谢：）

代码应该已经等待命令完成，因为

receiveWithin

是一种阻塞方法。您只需在

sleep 10

和

println

之前和之后运行示例

main

函数，就可以自己进行测试

从run函数中获取

布尔值

结果应该非常简单，您只需对run函数进行一个小的修改

新的

运行
功能：

def run(command:String) : Boolean = {
    println("gonna runa a command: " + Thread.currentThread)
    val args = command.split(" ")
    val processBuilder = new ProcessBuilder(args: _* )
    processBuilder.redirectErrorStream(true)
    val proc = processBuilder.start()

    //Send the proc to the actor, to extract the console output.
    reader ! proc

    //Receive the console output from the actor.
    //+========== Begin Modified Section ==============+
    //Here, we'll store the result instead of printing it, storing a None
    //if there was a timeout

    var commandResult : Option[String] = None
    receiveWithin(WAIT_TIME) {
        case TIMEOUT => commandResult = None
        case result:String => commandResult = Some(result)
    }

    //Here we interpret the result to return our boolean value
    commandResult match {
        case None => false
        case Some(s) => //... You'll have to transform the result to a true/false
            //however is most applicable to your use case
    }
}
