我正在运行一个程序，它会针对url生成一些负载，并使用RestTemplate进一步使用相同的URL。
我正在点击的网址会返回一个简单的字符串 Hello World 作为回复。
以下是将针对网址生成负载的程序。
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。我不确定导致这些例外的原因。谁能在这帮助我？

答案 0 :(得分：3)
java.lang.IllegalArgumentException：[0]没有匹配的常量 在org.springframework.http.HttpStatus.valueOf（HttpStatus.java:426）
异常消息表明您的服务器端代码生成了状态代码为0的响应，该响应无效。
你可以发布你的服务器端代码吗？
答案 1 :(得分：1)
我在使用Spring版本3时遇到了同样的错误，升级到4.2.2后它得到了解决。
答案 2 :(得分：-1)
我最近遇到了类似的问题。
我通过将 ClientHttpRequest 更改为 HttpComponentsClient 找到了解决方案。
这就是我所做的：
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
希望有所帮助
