SSLHandshakeException:握手期间远程主机关闭连接

Question

论坛上充斥着这个问题，但我找不到解决办法。我尝试连接WS，但没有成功。我试图更新cacerts文件，但没有效果。

日志是：

Allow legacy hello messages: true
Is initial handshake: true
Is secure renegotiation: false

很可能服务器已经禁用了TLS 1.0（您正在谈论TLS 1.0，如序列字节47 03 01 5A所示），或者它正在等待不存在的SNI扩展。

大约Java6，只有6u111将允许比TLS 1.0更好的东西（TLS 1.1），6u121将允许TLS 1.2。看看参考文献。由于TLS版本不容忍问题，它仍然是不充分的，只有系统属性才能永远启用它，如发行说明中所述：

TLS v1.2现在是此版本的TLS协议选项。默认情况下，TLSv1.0将保持客户端套接字上默认启用的协议。

因此，需要尝试几个系统属性：

• -Djdk。tls。客户协议=“TLSv1.2”（前提条件：6u121/7u95）

您的ClientHello格式正确，但不包含任何扩展名（特别是SNI）。这就是为什么它看起来如此短（字节=80）。默认情况下，SNI从6u121开始启用（如果我是对的话）。我看到的两个原因都应该用适当的Java版本来解决。
