我們正在使用帶有 Spring-Ws 的 Http Client 4.5.x 并使用該webServiceTemplate.marshalSendAndReceive(requestObject)方法發出請求。我們想要一個可靠的連接超時值，但目前遇到了第 8 節（DNS 循環）中描述的問題，其中嘗試了多個 IP 地址，因此超時是不可預測的。是否有簡單的方法可以僅使用 Spring-ws 和 Http Client 庫在一段時間后設置硬超時，或者是否需要設置某種自定義超時？案例：連接超時設置為 1 秒（該方法的實際超時為 4 秒——是否可以使用 Spring/Http 客戶端庫將方法超時設置為 1 秒？）應用程序日志（Http 客戶端日志設置為DEBUG）：16:45:02 (org.apache.http.impl.execchain.MainClientExec) Opening connection {}->http://salesforce.com:448 16:45:02 (org.apache.http.impl.conn.DefaultHttpClientConnectionOperator) Connecting to salesforce.com/96.43.149.26:448 16:45:03 (org.apache.http.impl.conn.DefaultHttpClientConnectionOperator) Connect to salesforce.com/96.43.149.26:448 timed out.
