java - Mongo Java 客户端 : How can I connect with SSL enabled but no certificate?

Question

为了测试，我设置了一个 mongodb 服务器，它允许在没有证书的情况下进行 ssl 连接。我可以使用 RoboMongo 和 mongo-c-driver 以这种方式连接，但是当我尝试 Java 时，我得到: {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}，由 {sun.security. validator.ValidatorException:PKIX 路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径}，由{sun.security.provider.certpath.SunCertPathBuilderException:无法找到有效证书路径引起要求的目标}}

我尝试将套接字工厂设置为使用默认套接字，但我得到: com.mongodb.MongoInternalException: SSL 已启用但套接字不是 javax.net.ssl.SSLSocket 的实例

我怎样才能建立这种联系？

所以基于通用SSL和this answer作者:ZZ Coder

MongoClient mongoClient = new MongoClient(serverAddress, 
Collections.singletonList(mongoCredential), MongoClientOptions.builder().sslEnabled(true).socketFactory(getNoopSslSoketFactory()).build());


private static SSLSocketFactory getNoopSslSocketFactory() {
    SSLContext sslContext;
    try {
        sslContext = SSLContext.getInstance("SSL");

        // set up a TrustManager that trusts everything
        sslContext.init(null, new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException { }

            @Override
            public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException { }

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        }}, new SecureRandom());
    } catch (NoSuchAlgorithmException | KeyManagementException e) {
        LOG.error("Couldn't create SSL Context for MongoDB connection", e);
        throw new RuntimeException(e);
    }
    return sslContext.getSocketFactory();
}
