无法连接到MongoDB云（ATlas）

Question

我们正在评估

我们正在尝试从Java应用程序连接到MongoDB云（Atlas）。 但观察例外。

组态：

• 在Ubuntu框上运行的Java测试应用程序
• MongoDB托管在MongoDB Cloud上（atlas，cloud.mongodb.com）
• DB配置为分片集群环境。

码

MongoURI uri = new MongoURI("mongodb://<USERNAME>:<PASSWORD>@<SERVERIP_1>,<SERVERIP_2>,<SERVERIP_3>/admin?replicaSet=EPCCAP-shard-0&ssl=true&authSource=admin");

SimpleMongoDbFactory dbF = new SimpleMongoDbFactory(uri);
DB db = dbF.getDb("capdb");
System.out.println(db.getCollectionNames());

Answer 1

一些建议

1. 您是否已将要尝试连接的Atlas群集中的IP地址列入白名单？

2. 个人通过java连接到我的Atlas集群时，我使用：

   MongoClientURI uri = new MongoClientURI（）; MongoClient mongoClient = new MongoClient（uri）; DB db = mongoClient.getDB（“”）;

3. 你在使用MongoDB的Java驱动程序吗？ 如果是这样，请确保它是3.4.2并且您在Java 8上运行。
