unable to find valid certification path to requested target 的简单解决办法

在使用httpClient执行Https的URL中出现此错误unable to find valid certification path to requested target 的简单解决办法！！

解决方法，在httpClient执行的之前调用此方法

 /**
     * Trust every server - dont check for any certificate
     */
    public static void trustAllHosts() {
        // Create a trust manager that does not validate certificate chains
        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return new java.security.cert.X509Certificate[] {};
                    }

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

                    public void checkServerTrusted(X509Certificate[] chain, String authType)
                            throws CertificateException {
                    }
                }
        };
    
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
