AWS EC2实例中某些停止工作的Spring引导应用程序
AWS EC2实例中某些停止工作的Spring引导应用程序
提问于 2022-09-27 07:30:01
我已经向AWS EC2实例部署了一个spring引导应用程序。很好用了一段时间。但一天后，应用程序就停止工作了。我使用了不同类型的EC2，从t2.micro到t3.media。只有一件事改变了。在较大的EC2实例中，应用程序在不停止的情况下工作时间更长。内存使用率不高。但是在CPU利用率方面发生了一些奇怪的事情。应用程序的CPU利用率低于2%，但突然达到50%，之后停止工作。
这是代码的主要部分。
@Scheduled(fixedDelay = 5, timeUnit = TimeUnit.SECONDS)
public void trackChanges() {
String uuid = UUID.randomUUID().toString();
log.info("Start processing new track changes with id {} at {}", uuid, LocalDateTime.now());
List<Pair<Asset, Fiat>> pairs = new ArrayList<>();
for (Asset asset : Asset.values()) {
for (Fiat fiat : Fiat.values()) {
pairs.add(new Pair<>(asset, fiat));
}
}
ExecutorService executorService = Executors.newFixedThreadPool(3);
CountDownLatch latch = new CountDownLatch(pairs.size());
for (Pair<Asset, Fiat> assetFiatPair : pairs) {
executorService.submit(() -> {
getProfit(assetFiatPair.getFirst(), assetFiatPair.getSecond());
latch.countDown();
});
}
try {
latch.await();
} catch (InterruptedException e) {
log.error("TrackChanges was interrupted!", e);
// Restore interrupted state...
Thread.currentThread().interrupt();
}
executorService.shutdown();
log.info("Finish processing new track changes with id {} on {}", uuid, LocalDateTime.now());
}
private void getProfit(Asset asset, Fiat fiat) {
Report report = binanceSearchService.check(asset, fiat);
if (!report.isEmpty()) {
CompareReport result = comparator.compare(report);
if (result.isChanged()) {
messageNotificator.sendMessage(result.getMessage());
}
}
