在java catch中无法用jsoup捕获异常

问题描述 投票：1回答：1

我想用jsoup解析一个网站，它成功地得到了我想要的细节，但我仍然得到很多例外而不是捕获

public static void main(String[] argv)
{
    getGoogle();
}

private static void getGoogle() {

    String url = "http://google.com";

    Document doc = null;

    try {

        doc = Jsoup.connect(url).get();
        Element body = doc.body();

    }catch (Exception e) {
        System.out.println("------------google------------");
        System.out.println("getGoogle:" + e.getMessage());
    }
}

当我使用调试模式时发现这是因为doc = Jsoup.connect(url).get();这行，但是在我搜索了很多信息之后看起来还不错，下面是我得到的例外情况
