Is it possible to timeout a task when using ThreadPoolTaskExecutor? I cannot change the ThreadPoolTaskExecutor to ThreadPoolExecutor or to ExecutorService.

推荐答案

在向您的 ThreadPoolTask​​Executor 提交 Callable 后，您应该得到一个 Future.而在这个Future上，你可以用一个TimeUnit调用get(long timeout, TimeUnit unit)函数，也就是超时，最大程序将通过抛出 TimeoutException 等待直到未来交付或继续进行的时间.

After submitting a Callable to your ThreadPoolTaskExecutor you should get a Future. And on this Future, you can call the get(long timeout, TimeUnit unit) function with a TimeUnit, which is the timeout, the maximum time the program will wait until either the future delivers or moves on, by throwing a TimeoutException.

即(未经证实的伪代码)

ie (unconfirmed pseudocode)

Future myFuture = threadPoolTaskExecutor.submit(myCallable);
try {
    myResult = myFuture.get(5l,TimeUnit.SECONDS);
} catch(TimeoutException e) {
    // Timeout-Related stuff here
}
