"java.security.cert.CertificateException: No name matching localhost found"无法在 Ubuntu 16.04 LTS 上解析

Question

• 我正在尝试从我的Ubuntu 16.04 Lts访问远程服务器。
• 我将远程服务器IP映射到" Localhost：60000"。

• 我能够通过Web浏览器以及curl命令访问服务器。我会按预期得到回应。

• 不幸的是，我无法从Java代码建立连接，这导致了以下异常，

线程中的异常" main" javax.net.ssl.sslhandshakeexception： java.security.cert.certificateException：没有匹配localhost的名称 找到

我确实在下面的链接中找到了解决方案：

• for Ubuntu 16.04：https：//www.digitalocean.com/community/tutorials/how-to-to-create-create-a-self-signed-signed-signed-ssl-certificate-for-apache-for-apache-in-apache-in-ubuntu-16---04

该问题在Ubuntu 14.04机器上解决，但在16.04机器上没有解决。谁能告诉我我在Ubuntu 16.04上做错了什么？
