我没有覆盖我的应用程序中的超时间隔。 谁能告诉我这个超时是通过哪个属性配置的？以及在哪里配置的？我认为它是在 axis2.xml 中配置的，但我可能是错的

Answer 1

我不太确定你的 promise 是什么，但 axis2 的源代码中设置了默认的 30 秒超时。

准确地说，在 org.apache.axis2.client.Options 第 118 行(axis2 版本 1.7.4):

public static final int DEFAULT_TIMEOUT_MILLISECONDS = 30 * 1000;

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

    return timeOutInMilliSeconds == -1 ? DEFAULT_TIMEOUT_MILLISECONDS
            : timeOutInMilliSeconds;

如果您想覆盖超时，我会建议您引用 axis documentation
