我一直在研究从动态Web应用程序中提取信息的程序,该程序运行正常,直到我将我的tomcat服务器设置为使用自签名(因此,不受信任)证书使用SSL.错误的堆栈跟踪是:

在Web浏览器中,当访问具有不受信任证书的HTTPS站点时,系统会向用户发出警告,并且如果他想继续,则要求例外; …

tl; dr：使用自定义 CA 而不将其添加到持久密钥库。

我正在编写一个应该使用 HTTPS 连接到远程服务器的 Java 应用程序。连接代码已准备就绪，但是服务器的 SSL 证书是由StartSSL签名的，它不在 Java 的 CA 根证书存储中。

使用此代码，我可以从以下网站获得有效的证书信息https://www.google.com/：
