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），可是客户端不支持或者未开启该版本java
我本地是开发，使用okhttp去访问的该https网站，这证实是该端协议不支持服务器
server:查看 本地开发端 server 支持与开启tls 信息socket
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：网站
Supported Protocols: 5 SSLv2Hello SSLv3 TLSv1 TLSv1.1 TLSv1.2 Enabled Protocols: 3 TLSv1 TLSv1.1 TLSv1.2
