获取 java.net.SocketTimeoutException：连接超时错误

Question

我正在尝试从我的应用程序连接到网络服务，但出现以下异常：

我没有在我的应用程序中覆盖超时间隔。任何人都可以告诉我这个超时是通过哪个属性配置的吗？它是在哪个地方配置的？我认为它是在 axis2.xml 中配置的，但我可能错了

Answer 1

我不太确定你承诺的是什么，但 axis2 的源代码中设置了 30 秒的默认超时。

要准确在org.apache.axis2.client.Options第118行（axis2版本1.7.4）：

public static final int DEFAULT_TIMEOUT_MILLISECONDS = 30 * 1000;

如果超时未手动设置且其默认值为 -1（例如第 504 行），则将使用此默认值。

    return timeOutInMilliSeconds == -1 ? DEFAULT_TIMEOUT_MILLISECONDS
            : timeOutInMilliSeconds;

如果你想覆盖超时我会推荐你参考axis documentation
