Question

我在使用Java Processbuilder运行批处理文件（＆＃34; Input.bat＆＃34;）时遇到问题，但是当我通过命令提示符（批处理）运行它时它按预期工作：

img { cursor:pointer }

问题是它没有将输入参数值写入文件＆＃34; Input.txt＆＃34;当我通过Processbuilder运行时。批次肯定会被执行但不会写任何来自＆＃34; ECHO％u％＆gt; INPUT.TXT＆＃34;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="page3">

有任何线索吗？

我认为，如果您从Process的InputStream中读取内容，而不是尝试将输出重定向到文件，那么您将获得更多成功。

例如：

//Start the builder and retrieve the created process
Proccess process = pb.start();
BufferedReader br;
String line;  

//Get the regular output from the process
br = new BufferedReader(new InputStreamReader(
  process.getInputStream()));

while((line = br.readLine()) != null)
{
  System.out.println(line);
}
br.close();

您还可以获得任何错误输出：

//Get error output
br = new BufferedReader(new InputStreamReader(
  process.getErrorStream()));

 while((line = br.readLine()) != null)
 {
   System.out.println(line);
 }
 br.close();

这两个InputStream将捕获发送到标准输出或标准错误的任何内容。一旦你捕获它，你可以随心所欲地做任何事情。
