Server chose TLSv1, but that protocol version is not enabled or not supported by the client.

javax.net.ssl.SSLHandshakeException: Server chose TLSv1, but that protocol version is not enabled or not supported by the client.

 报错显示：服务器端采用TLSv1 版本协议 （前身是ssl），但是客户端不支持或者未开启该版本

我本地是开发，使用okhttp去访问的该https网站，这证明是该端协议不支持

 

server:查看 本地开发端 server 支持与开启tls 信息

public static void main(String[] args) throws Exception {
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, null, null);

            SSLSocketFactory factory = (SSLSocketFactory) context.getSocketFactory();
            SSLSocket socket = (SSLSocket) factory.createSocket();

            String[] protocols = socket.getSupportedProtocols();

            System.out.println("Supported Protocols: " + protocols.length);
            for (int i = 0; i < protocols.length; i++) {
                System.out.println(" " + protocols[i]);
            }

            protocols = socket.getEnabledProtocols();

            System.out.println("Enabled Protocols: " + protocols.length);
            for (int i = 0; i < protocols.length; i++) {
                System.out.println(" " + protocols[i]);
            }

        }

结果：

Supported Protocols: 5
 SSLv2Hello
 SSLv3
 TLSv1
 TLSv1.1
 TLSv1.2
Enabled Protocols: 3
 TLSv1
 TLSv1.1
 TLSv1.2
