Java /Jsp 执行操作系统命令 windows/Linux

  Java /Jsp 执行操作系统命令 windows/Linux 收藏

1.Windows 很简单，写出来时为了和linux对比

   public void execWindowsCmd(String cmd) throws Exception {
      Runtime rt = Runtime.getRuntime();
      Process ppp = rt.exec(cmd);
      //input
      InputStreamReader ir = new InputStreamReader(ppp.getInputStream());
      LineNumberReader input = new LineNumberReader(ir);

      String line;
      while ((line = input.readLine()) != null)
         com.pub.Log.logger.debug(this.getClass().getClass() + " " +
                                           line);

      //error
      ir = new InputStreamReader(ppp.getErrorStream());
      input = new LineNumberReader(ir);
      while ((line = input.readLine()) != null)
         com.pub.Log.logger.debug(this.getClass().getClass() + " " +
                                           line);

      ppp.waitFor();
   }

2. Linux ：首先要确保对于命令，允许Web服务器的用户是否有权限，普通命令和windows没什么区别。Linux管道命令不能这样直接执行，下面是具体实现fang

   public void execLinuxCmd(String cmd) throws Exception {
      Runtime rt = Runtime.getRuntime();
      File f = new File(this.fileName + PDU_SHELL);
      BufferedWriter bw = new BufferedWriter(new FileWriter(f));
      bw.write("#!/bin/bash");
      bw.newLine();
      bw.write(cmd);  //把命令写入一个文本shell文件
      bw.flush();
      bw.close();
      cmd = f.getAbsolutePath();

      Process ppp = rt.exec("chmod a+x " + cmd);  //授权该shell文件可以执行
      ppp.waitFor();

      ppp = rt.exec(cmd);  //执行shell

      //input
      InputStreamReader ir = new InputStreamReader(ppp.getInputStream());
      LineNumberReader input = new LineNumberReader(ir);

      String line;
      while ((line = input.readLine()) != null)
         com.pub.Log.logger.debug(this.getClass().getClass() + " " +
                                           line);

      //error
      ir = new InputStreamReader(ppp.getErrorStream());
      input = new LineNumberReader(ir);
      while ((line = input.readLine()) != null)
         com.pub.Log.logger.debug(this.getClass().getClass() + " " +
                                           line);

      ppp.waitFor();

   }
