我得到javax.net.ssl.SSLHandshakeExc0019：远程主机在握手异常关闭连接，当我尝试做一个Web服务的Https获取

我的HTTP连接器配置：

   Connector connector = new Connector(Http11NioProtocol.class.getName());
   Http11NioProtocol protocol = (Http11NioProtocol) 
   connector.getProtocolHandler();
   protocol.setKeystoreFile("./Tests/Properties/keystore_local.ks");
   protocol.setKeystorePass("changeit");
   protocol.setSSLEnabled(true);
   protocol.setSslProtocol("TLS"); // TLSv1
   protocol.setClientAuth("true");
   protocol.setMaxThreads(200);
   protocol.setSecure(true);
   connector.setPort(443);
   protocol.setConnectionTimeout(30000);
   tomcat.getService().addConnector(connector);

无论如何，我可以对我的代码做些什么来解决这个问题吗？以下是完整的错误：

main, WRITE: TLSv1 Handshake, length = 48
main, received EOFException: error
main, handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
%% Invalidated:  [Session-2, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA]
main, SEND TLSv1 ALERT:  fatal, description = handshake_failure
main, WRITE: TLSv1 Alert, length = 32
main, called closeSocket()

Answer 1

你可以做两件事：你试图访问的url可能没有经过CA认证的证书，所以要求证书，或者你可以在cacerts（java运行时）中导入证书，然后尝试访问，否则第二：你可以禁用信任库（信任所有证书）从安全角度来看，这显然是不推荐的。

你可以参考这里

Answer 2

尝试更改协议。将SLS协议（“TLS”）设置为“TLSv1.1”或“TLSv1.2”

Answer 3

您正在使用TLSv1，但主机只接受TLSv1.1和TLSv1.2，那么您必须Java以下指令更改协议：

协议setProperty（“https.protocols”、“TLSv1.1”）；
