请求https接口时的SSLHandshakeException

最近，项目里请求https接口出现了以下异常问题：

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

问了度娘之后，有两种解决方案：

　　1、导入证书

　　　　传送门：https://blog.csdn.net/hzhahsz/article/details/84862285?utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromMachineLearnPai2%7Edefault-3.vipsorttest&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromMachineLearnPai2%7Edefault-3.vipsorttest

　　2、忽略证书验证

　　　　网上方法很多，我使用了以下方法，亲测有效：　

CloseableHttpClient client = HttpUtil.getIgnoeSSLClient();

/**
 * 获取忽略证书验证的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();

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