我正在創建一個測試應用程序,通過創建一組出站https連接(每個循環都在它自己的線程中)來加載測試彗星servlet。Java HttpsURLConnection出站限制?
併發出站http請求的數量是否有限制?如果是這樣,它是一個操作系統級別的問題(XP 32位)或Java?運行100個連接時出現以下異常。不會立即發生錯誤,但之間的任何地方50-150迴路(有時甚至更多),導致我以後懷疑它實際上可能是我沒有正確地釋放資源:

我的代碼:
while(true){
try{
connection =(HttpsURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("keep-alive", "true");
connection.setRequestMethod("GET");
input = new DataInputStream(connection.getInputStream());
b = new byte[4096];
totalBytes += input.read(b);
input.close();
b = null;
connection.disconnect();
connection = null;
Thread.sleep(100);
}
任何想法讚賞。
感謝, Dazz
謝謝,斷開連接似乎是必需的。解決的辦法是將http.maxConnections設置爲更高的數字。 – user481508
