爬虫客户端报错：javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol i

爬虫客户端报错：javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate

报错原因： SSL/TLS 协议版本不匹配：客户端支持的协议版本与服务器要求的版本不兼容。 加密套件不匹配：客户端支持的加密套件与服务器要求的加密套件不兼容。 服务器配置问题：服务器可能禁用了某些旧的协议或加密套件。 JVM 配置问题：运行时环境可能禁用了某些协议或加密套件。

解决：
