NIO+SSL 服务端报no cipher suites in common-优快云博客

本文链接：https://blog.youkuaiyun.com/Adomas/article/details/118706490

该博客主要讨论了在Java NIO结合SSL实现服务端时遇到的错误——'no cipher suites in common'。作者通过分享服务端代码，展示了如何配置和初始化SSLContext，以及在处理SSL握手时的问题。文章中提到，客户端连接时，由于加密套件不匹配导致SSL握手失败，服务端报错并关闭连接。博客旨在寻求问题的解决办法。

每次客户端一连，服务端就报javax.net.ssl.SSLHandshakeException: no cipher suites in common，连接就断了，求解释

服务端代码如下：
