java运行windows-bat文件

在Java中运行一个简单的bat文件。

我们使用 ProcessBuilder这样运行Windows批处理文件：

Java

 

1 2 3 4 5 6 7 8 9

ProcessBuilder processBuilder =         new ProcessBuilder("C:\\Users\\mkyong\\hello.bat");   //or       ProcessBuilder processBuilder = new ProcessBuilder();     processBuilder.command("cmd", "/c", "hello.bat");     File dir = new File("C:\\Users\\mkyong\\");     processBuilder.directory(dir);

或者， Runtime.getRuntime().exec像这样：

Java

 

1 2	Process process = Runtime.getRuntime().exec(         "cmd /c hello.bat", null, new File("C:\\Users\\mkyong\\"));

 

Java示例

bat文件路径  C:\\Users\\mkyong\\hello.bat

Java

 

1 2	@echo off echo Hello World

Java示例读取上面的bat文件并显示输出。

JavaRunBatFile.java

Java

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

package com.mkyong.concurrency;   import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader;   public class JavaRunBatFile {       public static void main(String[] args) {           ProcessBuilder processBuilder = new ProcessBuilder("C:\\Users\\mkyong\\hello.bat");                //Process process = Runtime.getRuntime().exec(         //            "cmd /c hello.bat", null, new File("C:\\Users\\mkyong\\"));                              try {               Process process = processBuilder.start();               StringBuilder output = new StringBuilder();               BufferedReader reader = new BufferedReader(                     new InputStreamReader(process.getInputStream()));               String line;             while ((line = reader.readLine()) != null) {                 output.append(line + "\n");             }               int exitVal = process.waitFor();             if (exitVal == 0) {                 System.out.println(output);                 System.exit(0);             } else {                 //abnormal...             }           } catch (IOException e) {             e.printStackTrace();         } catch (InterruptedException e) {             e.printStackTrace();         }       }   }

输出

Java

 

1	Hello World
