加入下面代码 是的 支持 https:

public static void initDefaultSSl() {
			if(init)
				return;
			
			try {
    	            SSLContext ctx = SSLContext.getInstance("TLS");
    	            X509TrustManager tm = new X509TrustManager() {
    	                public X509Certificate[] getAcceptedIssuers() {
    	                    return null;
    	                }
    					public void checkClientTrusted(X509Certificate[] chain,
    							String authType) throws CertificateException {
    						
    					}
    					public void checkServerTrusted(X509Certificate[] chain,
    							String authType) throws CertificateException {
    					}
    	            };
    	            ctx.init(null, new TrustManager[] { tm }, null);
    	            
    	           HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory());
    	           logger.info("HttpsURLConnection.setDefaultSSLSocketFactory");
    	        } catch (Exception ex) {
    	            ex.printStackTrace();
    	            
    	        }
			init=true;
		}
