我正在运行一个程序，它将针对 url 生成一些负载，并使用 RestTemplate 进一步使用相同的 URL。
我点击的 url 将返回一个简单的字符串Hello World作为响应。
下面是将对 url 生成负载的程序。
public class ShellbareboneLnP {
public static void main(String[] args) {
try {
// create thread pool with given size
ExecutorService service = Executors.newFixedThreadPool(threads);
// queue some tasks
long startTime = System.currentTimeMillis();
long endTime = startTime + (durationOfRun * 60 * 1000);
for (int i = 0; i < threads; i++) {
service.submit(new ShellBareboneTask(endTime));
}
service.shutdown();
service.awaitTermination(Long.MAX_VALUE, TimeUnit.DAYS);
} catch (InterruptedException e) {
LOG.warn("Threw a Interrupted Exception in" + CNAME + ".ShellbareboneLnP: boss told me to stop...Not my fault!!");
} catch (Exception e) {
LOG.warn("Threw a Exception in" + CNAME + e);
} finally {
}
}
}
class ShellBareboneTask implements Runnable {
private static final Logger LOG = Logger.getLogger(ShellBareboneTask.class.getName());
public static ConcurrentHashMap<String, AtomicInteger> exceptionMap = new ConcurrentHashMap<String, AtomicInteger>();
private final long endTime;
/**
* Constructor to pass the values
*
* @param durationOfRun
*/
public ShellBareboneTask(long endTime) {
this.endTime = endTime;
}
@Override
public void run() {
try {
RestTemplate restTemplate = new RestTemplate();
while (System.currentTimeMillis() <= endTime) {
PerformanceTimer timer = PerformanceTimer.getInstance();
restTemplate.getForObject("some_url", String.class);
timer.getDuration();
}
} catch (Exception e) {
handleException(e.getCause() != null ? e.getCause().toString() : e.toString());
e.printStackTrace();
}
}
}
每次程序运行一段时间后，我都会收到以下异常。我不确定是什么导致了这些异常。有人能帮我一下吗？
