獲取 java.net.SocketTimeoutException：連接超時錯誤

Question

我正在嘗試從我的應用程序連接到網絡服務，但出現以下異常：

我沒有覆蓋我的應用程序中的超時間隔。 誰能告訴我這個超時是通過哪個屬性配置的？在哪個地方配置？ 我認為它在axis2.xml中配置但我可能錯了

Answer 1

我不太確定你對它的承諾，但 30 秒的默認超時設置在軸 2 的源代碼中。

准確地說是在org.apache.axis2.client.Options第 118 行（axis2 版本 1.7.4）：

public static final int DEFAULT_TIMEOUT_MILLISECONDS = 30 * 1000;

如果 timout 未手動設置並且其默認值為 -1（例如第 504 行），則將使用此默認值。

    return timeOutInMilliSeconds == -1 ? DEFAULT_TIMEOUT_MILLISECONDS
            : timeOutInMilliSeconds;

如果您想覆蓋超時，我會向您推薦軸文檔
