Server: 
TLS Version: v1.2
Cipher Suite: TLS_RSA_WITH_AES_256_CBC_SHA256 

Client:
JRE 1.7

当我尝试通过SSL直接从客户端连接到服务器时,我收到以下错误:

Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
        at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)
        at sun.security.ssl.Alerts.getSSLException(Alerts.java:154)

以下代码启用TLSv1.2

  Set<String> enabledTLSSet = new HashSet<String>(Arrays.asList(sslsocket.getEnabledProtocols()));
  enabledTLSSet.add("TLSv1.2");      
  sslsocket.setEnabledProtocols(enabledTLSSet.toArray(new String[enabledTLSSet.size()]));

以下代码启用了TLS_RSA_WITH_AES_256_CBC_SHA256密码套件:

Set<String> enabledCipherSuitesSet = new HashSet<String>(Arrays.asList(sslsocket.getEnabledCipherSuites()));
      enabledCipherSuitesSet.add("TLS_RSA_WITH_AES_256_CBC_SHA256");
      sslsocket.setEnabledCipherSuites(enabledCipherSuitesSet.toArray(new String[enabledCipherSuitesSet.size()]));

从Java代码执行上述两个操作后,我可以通过SSL成功连接到服务器.

是否有可能使/力TLSv1.2和TLS_RSA_WITH_AES_256_CBC_SHA256Java 7中,而无需通过性能,参数或调试道具改变任何Java代码？

我尝试了所有形式和组合(启用和禁用)以及失败的所有以下属性.

-Dhttps.protocols=TLSv1.2
-Dhttps.cipherSuites=TLS_RSA_WITH_AES_256_CBC_SHA256
-Ddeployment.security.TLSv1.2=true

我正在执行类似下面的程序:

java -jar -Dhttps.protocols=TLSv1.2 -Dhttps.cipherSuites=TLS_RSA_WITH_AES_256_CBC_SHA256 Ddeployment.security.TLSv1.2=true -Djavax.net.debug=ssl:handshake SSLPoker.jar <SERVER> 443

SSLPoker包含以下代码:

package com.ashok.ssl;

import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
import java.io.*;
