== 我在这里看到：

try
{
..
Document doc = Jsoup.connect(recevurl).get();
..

}
catch (IOException| NullPointerException ee)
{
ee.printStackTrace();
}

我不知道如何解决这个异常？是否有一种方法可以处理它？我想IOException会处理它！

@学习者- 你是否在代理后面？如果是，则设置Java代理设置并尝试，否则增加超时时间将无效。 - Favonius

尝试 Document doc = Jsoup.connect(recevurl).timeout(3000).get();

谢谢Alrex。它提示一种类型为doc的方法timeout(int)未定义。 - The Learner

顺序错误。请尝试使用Document doc = Jsoup.connect(recevurl).timeout(3000).get();。 - ollo

@ollo 谢谢！我希望这会有所帮助（在我的情况下是这样的）。 - Alex Nevsky

可以将超时时间设置为0（无限超时）。 - Sachin
