如何使用Java将“MongoSocketException”修复到外部MongoDB？

Question

我正在尝试使用以下代码将我的java spring启动服务器连接到我的外部mongoDB：

MongoClientURI uri = new MongoClientURI(
                "mongodb+srv://username:password@integrationcourse-7bsmm.mongodb.net/test?retryWrites=true");

        MongoClient mongoClient = new MongoClient(uri);
        MongoDatabase database = mongoClient.getDatabase("course");
        MongoCollection<Document> collection = database.getCollection("UserEntitys");

而且我得到以下错误：

com.mongodb.MongoSocketException: integrationcourse-7bsmm.mongodb.net

使用了来自地图册的一个较旧的url样本，将其固定，然后连接到数据库。 如建议。
