jsoup访问页面: PKIX path building failed

在用jsoup访问页面时报错 javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

这是由于安全认证的问题，网上解决办法很多， 我们只需要在Jsoup.connect(webSite)之前添加方法忽略证书信任问题
