使用Java访问https接口javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

jdk1.6，证书：SHA256+TLSv1.2

使用Java访问https://**************** 接口     控制台提示握手失败错误；javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

     解决办法：    

1.jdk版本问题，换用jdk1.7；

2.如不能更换jdk版本，引入 bcprov-jdk15on-157.jar 此jar包对jdk1.5-1.8都可支持；

public static String httpsRequsetForTLSv12(String host, String url) throws Exception {
java.security.SecureRandom secureRandom = new java.security.SecureRandom();
Socket socket = new Socket(java.net.InetAddress.getByName(host), 443);
TlsClientProtocol protocol = new TlsClientProtocol(socket.getInputStream(), socket.getOutputStream(),secureRandom);
DefaultTlsClient client = new DefaultTlsClient() {
public TlsAuthentication getAuthentication() throws IOException {
TlsAuthentication auth = new TlsAuthentication() {
public void notifyServerCertificate(org.bouncycastle.crypto.tls.Certificate serverCertificate) throws IOException {
}

public TlsCredentials getClientCredentials(CertificateRequest certificateRequest) throws IOException {
return null;
}
};
return auth;
}
};
protocol.connect(client);
java.io.OutputStream output = protocol.getOutputStream();
output.write(("GET "+url+" HTTP/1.1\r\n").getBytes("UTF-8"));
output.write(("Host: "+host+"\r\n").getBytes("UTF-8"));
output.write("Connection: close\r\n".getBytes("UTF-8"));
output.write("\r\n".getBytes("UTF-8"));
output.flush();

java.io.InputStream input = protocol.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input, "UTF-8"));
String line;
String result = null;
while ((line = reader.readLine()) != null)
{
result = line;
//System.out.println(line);
}
return result;
}
