如何將HttpClientConnectionManager
上的超時設置爲超過2分鐘?在Apache 4.x客戶端中控制請求超時
我們正在連接一個長時間運行的SOAP服務,它在返回HTTP響應之前處理幾(5-8)分鐘。我們無法控制此服務,因此我們需要在收到響應之前允許長時間的活動。
使用Apache的HttpClient 4.3.2庫我們注意到連接管理器似乎在2分鐘後關閉連接由於不活動:
16:14:45.805 DEBUG o.a.h.headers.onRequestSubmitted(124) - http-outgoing-0 >> POST /someendpoint.do?SOAP HTTP/1.1

我們試圖connMgr.closeIdleConnections(10, TimeUnit.MINUTES);
,指定我們自己ConnectionKeepAliveStrategy
,並設置超時在請求配置:
config = RequestConfig.copy(RequestConfig.DEFAULT)
.setSocketTimeout(soTimeout)
.setConnectTimeout(connTimeout)
.setConnectionRequestTimeout(rqTimeout)
.build();
是我們缺少一些輔助設置,如設置超時這裏還設置一個標誌there or that this and that are set the same value?
當服務器預計不會響應超過2分鐘時,防止連接關閉的正確方法是什麼?
謝謝@oleg。我們正在確認代理超時,但我們已經被告知它已設置爲5分鐘。 – SCote
