您可以执行Thread.join（long）或Thread.join（long，int）并在单独的线程中启动进程。
public class Test {
public static void main(String[] args) throws Throwable {
for(int i = 0; i < 3; i++) {
ProcessRunner pr = new ProcessRunner(args);
pr.start();
// wait for 100 ms
pr.join(100);
// process still going on? kill it!
if(!pr.isDone()) {
System.err.println("Destroying process " + pr);
pr.abort();
}
}
}
static class ProcessRunner extends Thread {
ProcessBuilder b;
Process p;
boolean done = false;
ProcessRunner(String[] args) {
super("ProcessRunner " + args); // got lazy here :D
b = new ProcessBuilder(args);
}
public void run() {
try {
p = b.start();
// Do your buffered reader and readline stuff here
// wait for the process to complete
p.waitFor();
}catch(Exception e) {
System.err.println(e.getMessage());
}finally {
// some cleanup code
done = true;
}
}
int exitValue() throws IllegalStateException {
if(p != null) {
return p.exitValue();
}
throw new IllegalStateException("Process not started yet");
}
boolean isDone() {
return done;
}
void abort() {
if(! isDone()) {
// do some cleanup first
p.destroy();
}
}
}
}
