Jsoup抓取网页内容超时问题的处理

在利用Jsoup抓取网页的时候，遇到超时问题：

java.net.SocketTimeoutException: Read timed out

我一开始代码里面是：

Jsoup.connect(url).cookie("JSESSIONID", sessionId).get();

方法获取网页内容，这种方式使用的是默认超时时间3秒。

由于请求数据慢，就会造成超时的，修改成如下就可以了：
Jsoup.connect(url).cookie("JSESSIONID", sessionId).timeout(50000).get(); // 50S
这个时间，自己看着设置！
