我正在使用ExecutorService
实现一个3线程池,并使用CountDownLatch监控所有线程的完成情况,以便进行后续处理。
ExecutorService threadExecutor = Executors.newFixedThreadPool(3);
CountDownLatch countDownLatch = new CountDownLatch(3);
AuthorisationHistoryTask task1 =
new AuthorisationHistoryTask(commonDataThread, countDownLatch );
PreAuthHistoryTask task2 =
new PreAuthHistoryTask(userID,sessionID, commonDataThread, countDownLatch );
SettlementHistTask task4 = new SettlementHistTask(commonDataThread,countDownLatch);
Future<Map<String, Object>> futureAuthHistory = threadExecutor.submit (task1);
Future<Map<String, Object>> futurePreAuthHist = threadExecutor.submit (task2);
Future<Map<String, Object>> futureSettleHist = threadExecutor.submit(task4);
threadExecutor.shutdown();
try {
countDownLatch.await();
}catch (InterruptedException e) {
logger.logCommon("InterruptedException",CLASS_NAME);
}catch (ExecutionException ex) {
logger.logCommon("InterruptedException",CLASS_NAME);
}
我已经使用了
countDownLatch.await()
来等待所有线程完成。如果超时,比如说45秒,我希望能够中止这个进程 countDownLatch.await()
。我该如何实现?
