請求https接口時的SSLHandshakeException

最近，項目里請求https接口出現了以下異常問題：

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

問了度娘之后，有兩種解決方案：

　　1、導入證書

　　2、忽略證書驗證

　　　　網上方法很多，我使用了以下方法，親測有效：　

CloseableHttpClient client = HttpUtil.getIgnoeSSLClient();

/**
 * 獲取忽略證書驗證的client
 *
 * @return
 * @throws Exception
 */
public static CloseableHttpClient getIgnoeSSLClient() throws Exception {
    SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
            return true;
        }
    }).build();

    //創建httpClient
    CloseableHttpClient client = HttpClients.custom().setRedirectStrategy(new LaxRedirectStrategy())
            .setSSLContext(sslContext).setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
    return client;
}
