MongoDB的身份驗證失敗我試圖連接使用蒙戈Java客戶端3.2版，並收到以下異常，任何想法有什麼錯在這裏去蒙戈DB 3.2版？從蒙戈Java客戶端

以下是我用來連接的代碼。

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(); 
    }

您已經添加上「MyDatabase的」或「admin」的用戶（這是默認的）？換句話說，在createMongoCRCredential中嘗試使用「admin」作爲數據庫。 – mtj

@Zeus代碼似乎是正確的。我也這樣做，並沒有問題連接到我的服務器。在身份驗證期間檢查服務器上的日誌是否有錯誤。 https://docs.mongodb.com/manual/reference/system-users-collection/ – neomega

可以請身邊的人的問題，調試了幾個小時之後，數據庫管理員告知，他已經改變了用戶名和密碼。有時我想知道我爲什麼成爲一名軟件工程師。 –
