我的程序应该在多线程上运行很长时间。 我需要能够为线程设置超时,一旦线程终止,我想再次启动它。 这是我的代码:
@Test
public void testB() throws InterruptedException {
final ExecutorService threadPool = Executors.newFixedThreadPool(2);
for(int i=0; i<2; i++){
threadPool.submit(new Runnable() {
public void run() {
System.out.println("thread start: " + Thread.currentThread().getName());
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
}
threadPool.shutdown();
threadPool.awaitTermination(100000, TimeUnit.SECONDS);
}
答案 0 :(得分:1)
下面的代码会一遍又一遍地对任务执行相同的操作。 在给定的时间后,池将被关闭。
这似乎符合您的要求。
final ExecutorService threadPool = Executors.newFixedThreadPool(2);
for(int i = 0; i < 2; i++){
final int taskNb = i;
threadPool.submit(new Runnable() {
public void run() {
System.out.println("Thread " + taskNb + " start: " + Thread.currentThread().getName());
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// Submit same task again
threadPool.submit(this);
}
});
}
// Only shutdown the pool after given amount of time
Thread.sleep(100_000_000);
threadPool.shutdown();
// Wait for running tasks to finish
threadPool.awaitTermination(5, TimeUnit.SECONDS);
