【问题描述】：

我正在尝试从 java 连接到 mongodb atlas 集群，出现以下错误：

Caused by: com.mongodb.MongoCommandException: Command failed with error 8000 (AtlasError): 'Authentication failed.' on server cluster0-shard-00-00-wgrdw.gcp.mongodb.net:27017. The full response is {"ok": 0, "errmsg": "Authentication failed.", "code": 8000, "codeName": "AtlasError"}

我的地图集配置：

用户：admin，密码：...
ip 白名单：0.0.0.0/0（用于测试目的）
mongodb版本：4.0.6
java驱动：implementation (group: 'org.mongodb', name: 'mongo-java-driver', version: '3.10.1')

Java 代码：

List<ServerAddress> seeds = new ArrayList<>();
        seeds.add(new ServerAddress("cluster0-shard-00-00-wgrdw.gcp.mongodb.net", 27017));
        seeds.add(new ServerAddress("cluster0-shard-00-01-wgrdw.gcp.mongodb.net", 27017));
        seeds.add(new ServerAddress("cluster0-shard-00-02-wgrdw.gcp.mongodb.net", 27017));

        MongoCredential credential = MongoCredential.createCredential(USER, "vehicle-data", PWD.toCharArray());

        MongoClientOptions.Builder builder = new MongoClientOptions.Builder();
        //build the connection options
        builder.maxConnectionIdleTime(60000);//set the max wait time in (ms)
        builder.sslEnabled(true);
        MongoClientOptions opts = builder.build();

        MongoClient mongoClient = new MongoClient(seeds, credential, opts);

        MongoDatabase database = mongoClient.getDatabase("vehicle-data");
        MongoCollection<Document> segments = database.getCollection("road-segments");
        // Delete All documents from collection Using blank BasicDBObject
        segments.deleteMany(new BasicDBObject());

有人知道我错过了什么吗？

也许检查一下它可能会有所帮助jira.mongodb.org/browse/JAVA-2817

【解决方案1】：

解决了（在 atlas 帮助台的帮助下）：

将服务器/节点配置更改为：

MongoClientURI uri = new MongoClientURI(
                "" +
                        "mongodb://admin:<pwd>@" +
                        "cluster0-shard-00-00-wgrdw.gcp.mongodb.net:27017," +
                        "cluster0-shard-00-01-wgrdw.gcp.mongodb.net:27017," +
                        "cluster0-shard-00-02-wgrdw.gcp.mongodb.net:27017/vehicle-data?" +
                        "ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true" +
                        ""
        );
        MongoClient mongoClient = new MongoClient(uri);
        MongoDatabase database = mongoClient.getDatabase("vehicle-data");

现在可以了
