java - HtmlUnit - PKIX 路径构建失败 : unable to find valid certification path to requested target

Question

我在 Glassfish 上有一个使用 GoDaddy SSL 证书的 JAVA EE webapp。 HTTP 监听器重定向到 HTTPS 监听器。

我正在尝试让 HtmlUnit 从用于 Googlebot 爬虫的网络应用程序中获取页面。该代码在未启用 SSL 的登台服务器上按预期工作。但是，在使用 GoDaddy SSL 证书的实时服务器上，当 HtmlUnit 尝试获取网页时出现以下错误。

我已经尝试了此处指定的解决方法 ( http://www.mkyong.com/webservices/jax-ws/suncertpathbuilderexception-unable-to-find-valid-certification-path-to-requested-target/ )，但没有帮助。关于为什么我会收到此错误的任何想法？

解决方法是在请求的页面上禁用 SSL。当然不是一回事，但这种废话太烦人了。要禁用 SSL，请在 webClient 对象上使用以下命令:

 webClient.getOptions().setUseInsecureSSL(true);
