如何强制Commons HTTPClient 3.1仅对HTTPS使用TLS 1.2？

Question

我希望强制 Apache Commons HTTP-Client （版本 3.1 ）将 TLS 1.2 用作HTTPS 的
唯一
协议。

这是由于服务器应该升级到TLS 1.2，并且不再接受任何较旧的协议（导致返回“连接重置”）。

对于进一步的上下文（可能无关紧要），HTTP客户端与Axis2一起使用来创建SOAP；下面是用于设置HttpClient的一些代码：

MultiThreadedHttpConnectionManager connMgr = new MultiThreadedHttpConnectionManager();
this.httpClient = new HttpClient(connMgr);

// initialize HttpClient parameters
HttpClientParams hcParams = this.httpClient.getParams();

// Maximum time to wait to receive connection from pool
hcParams.setConnectionManagerTimeout(this.maxWait);
hcParams.setSoTimeout(this.timeout);
hcParams.setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler(this.retryCount, false));

// Initialize global Connection manager parameters
HttpConnectionManagerParams cmParams = connMgr.getParams();
cmParams.setDefaultMaxConnectionsPerHost(this.maxActive);
cmParams.setStaleCheckingEnabled(this.checkStaleConnections);
cmParams.setConnectionTimeout(this.timeout);

非常感谢您的帮助！

太可惜了，没人回答。我能够做到，首先编写一个 CustomHttpSocketFactory ，然后执行以下操作：

String scheme = "https";
Protocol baseHttps = Protocol.getProtocol(scheme);
int defaultPort = baseHttps.getDefaultPort();

ProtocolSocketFactory baseFactory = baseHttps.getSocketFactory();
ProtocolSocketFactory customFactory = new CustomHttpsSocketFactory(baseFactory);

Protocol customHttps = new Protocol(scheme, customFactory, defaultPort);
Protocol.registerProtocol(scheme, customHttps);

在这里找到了示例自定义套接字工厂代码，但是我做了：

public class CustomHttpsSocketFactory implements SecureProtocolSocketFactory
{

   private final SecureProtocolSocketFactory base;

   public CustomHttpsSocketFactory(ProtocolSocketFactory base)
   {
      if(base == null || !(base instanceof SecureProtocolSocketFactory)) throw new IllegalArgumentException();
      this.base = (SecureProtocolSocketFactory) base;
   }

   private Socket acceptOnlyTLS12(Socket socket)
   {
      if(!(socket instanceof SSLSocket)) return socket;
      SSLSocket sslSocket = (SSLSocket) socket;
      sslSocket.setEnabledProtocols(new String[]{"TLSv1.2" });
      return sslSocket;
   }

   @Override
   public Socket createSocket(String host, int port) throws IOException
   {
      return acceptOnlyTLS12(base.createSocket(host, port));
   }
   @Override
   public Socket createSocket(String host, int port, InetAddress localAddress, int localPort) throws IOException
   {
      return acceptOnlyTLS12(base.createSocket(host, port, localAddress, localPort));
   }
   @Override
   public Socket createSocket(String host, int port, InetAddress localAddress, int localPort, HttpConnectionParams params) throws IOException
   {
      return acceptOnlyTLS12(base.createSocket(host, port, localAddress, localPort, params));
   }
   @Override
   public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException
   {
      return acceptOnlyTLS12(base.createSocket(socket, host, port, autoClose));
   }

}
