Java /Jsp 执行操作系统命令 windows/Linux

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();

}
