使用RestTemplate调用https请求报此错误 需修改一下https协议

RestTemplate restTemplate = new RestTemplate(new HttpsClientRequestFactory());

public class HttpsClientRequestFactory extends SimpleClientHttpRequestFactory {
    @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) {
        try {
            if (!(connection instanceof HttpsURLConnection)) {// http协议
                // throw new RuntimeException("An instance of HttpsURLConnection is expected");
                super.prepareConnection(connection, httpMethod);
            }
            if (connection instanceof HttpsURLConnection) {// https协议，修改协议版本
                KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
                // 信任任何链接
                TrustStrategy anyTrustStrategy = new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                        return true;
                    }
                };
                SSLContext ctx = SSLContexts.custom().useTLS().loadTrustMaterial(trustStore, anyTrustStrategy).build();
                ((HttpsURLConnection)connection).setSSLSocketFactory(ctx.getSocketFactory());
                HttpsURLConnection httpsConnection = (HttpsURLConnection)connection;
                super.prepareConnection(httpsConnection, httpMethod);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
