1.代码

public static String runCmd(String cmdpath, String cmd) {
		log.info(cmd);
		String result="";
		File dir = new File(cmdpath);
		try {
			Process ps = Runtime.getRuntime().exec(cmd, null, dir);
	
			BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream(), Charset.forName("GBK")));
			String line = null;
			while ((line = br.readLine()) != null) {
				System.out.println(line);
				result+=line+"\n";
			}

			br.close();
			System.out.println("close ... ");
			ps.waitFor();
			System.out.println("wait over ...");
			
			return result;
		} catch (IOException ioe) {
			ioe.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		System.out.println("child thread donn");
		return null;
	}

2.测试

public static void main(String args[]){
		runCmd("C:\\","ping www.baidu.com");
	}
