java发送https请求忽略ssl证书验证

最近在项目终于遇到了一个https的问题，在开发环境发起https请求没有问题，一切正常，但是到了生产环境却报错了，报错信息如下：

ssl证书验证不通过，有两种解决的方法，一种办法就是下载对应的ssl证书，并且加入到jdk可信任证书列表，另一个比较简单，但是不怎么推荐的操作，我们可以忽略https的证书验证，直接请求，解决代码：

URL url = new URL(urlString);
            //忽略证书
            /*if("https".equalsIgnoreCase(url.getProtocol())){
                SslUtils.ignoreSsl();
            }*/
            trustAllHosts();

            if (url.getProtocol().toLowerCase().equals("https")) {
                HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
                https.setHostnameVerifier(DO_NOT_VERIFY);
                urlConnection = https;
            } else {
                urlConnection = (HttpURLConnection) url.openConnection();
            }


private 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) {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) {
            }
        } };
        // Install the all-trusting trust manager
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };
