HttpURLConnection绕过HTTPS的SSL验证

（这个jdk环境需要是1.8,以上）。

直接在类里面加一个static代码块

 static {
         try {
             trustAllHttpsCertificates();
             HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
                 public boolean verify(String urlHostName, SSLSession session) {
                     return true;
                 }
             });
         } catch (Exception e) {
         }
     }

　　在调用如下方法：

 private static void trustAllHttpsCertificates() throws NoSuchAlgorithmException, KeyManagementException {
         TrustManager[] trustAllCerts = new TrustManager[1];
         trustAllCerts[0] = new TrustAllManager();
         SSLContext sc = SSLContext.getInstance("SSL");
         sc.init(null, trustAllCerts, null);
         HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
     }

     private static class TrustAllManager implements X509TrustManager {
         public X509Certificate[] getAcceptedIssuers() {
             return null;
         }

         public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
         }

         public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
         }
     }

这样就应该没有问题了。
