1、访问https的网站，下载https证书

![Center][]

保存证书后，是一个.cer文件。

2、利用jdk的toolkey工具，将证书转换成密钥的形式

![Center 1][]

![Center 2][]

3、代码：

public static void main(String[] args) throws ClientProtocolException, IOException, KeyStoreException, NoSuchAlgorithmException, CertificateException, KeyManagementException, UnrecoverableKeyException {
            DefaultHttpClient client = new DefaultHttpClient();
            client.getParams().setParameter(ClientPNames.COOKIE_POLICY,CookiePolicy.BROWSER_COMPATIBILITY);
            client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "    Mozilla/5.0 (Windows NT 6.2; rv:18.0) Gecko/20100101 Firefox/18.0");
            String PostFir = "https://www.xxx.com/";
            //获得密匙库
              KeyStore trustStore  = KeyStore.getInstance(KeyStore.getDefaultType());
              FileInputStream instream = new FileInputStream(new File("d:/zzaa/steven.keystore"));
              //密匙库的密码
              trustStore.load(instream, "123456".toCharArray());
              //注册密匙库
              SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
              //不校验域名
              socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
              Scheme sch = new Scheme("https", 443, socketFactory);
              client.getConnectionManager().getSchemeRegistry().register(sch);
            HttpPost httppost1 = new HttpPost(PostFir);
            HttpResponse    response1 = client.execute(httppost1);
            HttpEntity resEntity1 = response1.getEntity();
        System.out.println(EntityUtils.toString(resEntity1,"gbk"));
         
        }
