Question

我正在尝试从Java代码连接到Mongo DB Server。我能够从命令行连接到同一台服务器。但是当我从Java代码进行连接时，遇到了一些问题。
下面是我用来连接数据库的命令行：

mongo --username user --password pwd --authenticationDatabase authDB --ssl --host xxx.yyy.com --port 37043

我能够与上述命令行连接。我正在使用下面的Java代码连接到MongoDB：

MongoClientOptions.Builder options = MongoClientOptions.builder().sslInvalidHostNameAllowed(true);
String url="mongodb://user:pwd@xxx.yyy.com:37043/authDB?ssl=false"
MongoClient client = new MongoClient(new MongoClientURI(url,options));
System.out.println("Opion"+client.getDatabaseNames());

我收到以下异常：

注意：我也尝试从MongoDB Compass连接到同一服务器。我能够成功连接。在MongoDBCompass中，我选择SSL作为Unvalidated(insecure)和SSHTunnel作为None。

如果从Java代码连接时缺少某些内容，请提供帮助。

从Java连接到MongoDB会引发错误？
