以下是我用来连接的代码。

MongoClient mongoClient = null; 

    try { 
     MongoCredential credential = MongoCredential.createMongoCRCredential("admin", "mydatabase", "admin123".toCharArray()); 
     mongoClient = new MongoClient(new ServerAddress("10.100.5.41", 27017), Arrays.asList(credential)); 

     MongoDatabase database = mongoClient.getDatabase("mydatabase"); 
     System.out.println(database.getName()); 
     MongoCollection collection = database.getCollection("user"); 

     MongoCursor cursor = collection.find().iterator(); 
     while (cursor.hasNext()) { 
      System.out.println(cursor.next()); 
     } 

    } catch (Exception e) { 
     e.printStackTrace(); 
    }

您已经添加上“MyDatabase的”或“admin”的用户(这是默认的)?换句话说,在createMongoCRCredential中尝试使用“admin”作为数据库。 – mtj

@Zeus代码似乎是正确的。我也这样做,并没有问题连接到我的服务器。在身份验证期间检查服务器上的日志是否有错误。 https://docs.mongodb.com/manual/reference/system-users-collection/ – neomega

可以请身边的人的问题,调试了几个小时之后,数据库管理员告知,他已经改变了用户名和密码。有时我想知道我为什么成为一名软件工程师。 –
