如何使用Java运行批处理文件 [英] how to run a batch file using java

问题描述

我想使用Java程序运行批处理文件，当我双击.bat文件时，它要求我输入'D'，然后在C驱动器中创建一些文件夹，下面是.bat的内容文件：

I want to run a batch file using a java program, when I double click the .bat file it asks me to enter 'D' and after that it creates some folders in C drive, below is the contents of the .bat file:

xcopy "data" "C:\data" /S
xcopy "rapid" "C:\rapid" /S
subst x: /D
subst x: C:\

我的Java代码如下：

My Java code is as below:

try {
            //C:\Desktop\Speed\view_R36_WD_Release\RAPID\switchToLive.Bat
            String cmds[] = {"C:\\Users\\608521747\\Desktop\\Speed\\view_R36_WD_Release\\RAPID\\switchToDev.bat"};
            Runtime runtime = Runtime.getRuntime();
            Process process = runtime.exec(cmds);
            process.getOutputStream().close();
            InputStream inputStream = process.getInputStream();
            InputStreamReader inputstreamreader = new InputStreamReader(inputStream);
            BufferedReader bufferedrReader = new BufferedReader(inputstreamreader);
            String strLine = "";
            while ((strLine = bufferedrReader.readLine()) != null) {
                System.out.println(strLine);
            }
        } catch (IOException ioException) {
            ioException.printStackTrace();
        } 

它不会给我任何错误，但是它既不要求我输入任何值也不它会创建任何文件夹。

its not giving me any errors but it neither ask me to enter any value nor it creates any folder.

我想知道我需要在Java代码中做什么，以便它会要求我输入'D'，然后输入.bat。文件应该继续正常运行。

I want to know what do I need to do in java code so that it will ask me to enter the 'D' and then the .bat file should continue in a normal flow.

我们将不胜感激。

推荐答案

批处理文件不是可执行文件。因此，您将需要运行cmd.exe并将批处理文件作为参数传递。

Batch files are not executable files. So you will need to run cmd.exe and pass the batch file as parameter.
