我的应用程序必须与Maria数据库实例建立SSL连接。
这是我的连接字符串
jdbc:mariadb://<serverName>:3306/<dbName>?serverSslCert=<path to server cert>&jdbcCompliantTruncation=false&verifyServerCertificate=true&useSSL=true&enabledSslProtocolSuites=TLSv1.1&autoReconnect=true
这工作正常，但现在我的应用程序需要创建一个https连接并提供客户端证书。
HttpClientBuilder hcb = HttpClients.custom();
hcb.useSystemProperties();
hcb.setUserAgent(AGENT);
hcb.setDefaultCookieStore(new BasicCookieStore());
SSLContext sslContext = SSLContexts.createSystemDefault();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
hcb.setSSLSocketFactory(sslsf);
client = hcb.build();
当我使用 javax.net.ssl.keyStore 设置启动我的应用程序时，我收到以下异常

因此，应用程序似乎可以建立安全的数据库连接（必需）或将自身标识为http服务器（也是必需的）。
我正在使用 mariadb-java-client-1.6.2.jar 但是已经尝试了与Java 7（1.7.1）兼容的最新版本，但仍然会遇到同样的错误。
我的主要问题是，我做错了什么，或者在设置 javax.net.ssl.keyStore 时是否无法使用与mariadb的安全连接？我是否需要将（mariadb）服务器证书放入密钥库？
除此之外，还有其他一些方法可以让我的 HttpClient 使用密钥库而不通过 javax.net.ssl.keyStore 提供吗？
