Runtime.getRuntime().exec(...)使用方法

Runtime.getRuntime().exec(...)使用方法

如果想要了解更多的信息，参阅代码里面给的链接

下面是这个正确的例子

public class RuntimeExec {
/**
* Runtime execute.
*
* @param cmd the command.
* @return success or failure
* @see {@link http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=4} * @since 1.1
*/
public static boolean runtimeExec(String cmd) {

try {
Process proc = Runtime.getRuntime().exec(new String[]{"/bin/sh", "-c", cmd});

// any error message?
StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR");

// any output?
StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT");

// kick them off
errorGobbler.start();
outputGobbler.start();

if (proc.waitFor() != 0) {
System.err.println("执行\"" + cmd + "\"时返回值=" + proc.exitValue());

return false;

} else {
return true;
}
} catch (Exception e) {
e.printStackTrace();
return false;
}
}

static class StreamGobbler extends Thread {

InputStream is;
String type;

StreamGobbler(InputStream is, String type) {
this.is = is;
this.type = type;
}

public void run() {
try {
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null)

System.out.println(type + ">" + line);
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}

}
