Java Runtime.exec() hangs

有一篇总结的很不错的文章：

/javaworld/jw-12-2000/jw-1229-traps.html?page=3

有两种方法可以解决这个问题：

1.采用apache common exec

2.采用多线程

public static void main(String[] args) {try {Process process = Runtime.getRuntime().exec("E:\\test\\dbbackup.cmd");new MyThread(process.getErrorStream()).start();new MyThread(process.getInputStream()).start();int status = process.waitFor();if (status == 0) {System.out.println("exit success");} else {System.out.println("exit fail");}} catch (Exception e) {System.out.println("exception occurs......");e.printStackTrace();}}public class MyThread extends Thread{BufferedReader bf;public MyThread(InputStream input){bf=new BufferedReader(new InputStreamReader(input));}public void run(){String line;try {line = bf.readLine();while(line!=null){System.out.println(line);line=bf.readLine();}} catch (IOException e) {e.printStackTrace();}}}
