用于测量服务器响应时间的等效java代码

Question

我应该使用以下C#代码的等效java api是什么？我需要的是检查响应时间.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
System.Diagnostics.Stopwatch timer = new Stopwatch();
timer.Start();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
timer.Stop();
TimeSpan timeTaken = timer.Elapsed;

提前致谢.

Answer 1

尝试:

long start = System.currentTimeMillis();
//doSth.

long elapsed = System.currentTimeMillis() - start;

为了获得更高的精度,您可以使用System.nanoTime()它返回两次调用之间的纳秒.请注意这个:This method provides nanosecond precision, but not necessarily nanosecond accuracy.

从URL读取并测量速度的简单方法可能是:

 long start = System.currentTimeMillis();
 URL url = new URL(urlString);  
 url.getContent();
 long elapsed = System.currentTimeMillis() - start;
