我有以下代码保存到本地运行的 mongo 实例：

MongoCredential credential = MongoCredential.createCredential("myuser", "mydatabase", "mypassword".toCharArray());

MongoClient mongo = MongoClients.create(MongoClientSettings.builder()
                    .applyToClusterSettings(builder -> builder.hosts(Arrays.asList(new 
ServerAddress("localhost", 27017))))
                    .credential(credential)
                    .build());
MongoDatabase database = mongo.getDatabase("mydatabase");
MongoCollection<Document> collection = database.getCollection("mycollection");
collection.insertOne(document);

我在 mongo.exe shell 中使用 db.createUser() 命令为上面代码中使用的 usernmae/password 创建了一个用户，这些与我在安装 mongodb 时提供的凭据相同。

db.createUser(
{   user: "myuser",
    pwd: "mypassword",

    roles:[{role: "userAdminAnyDatabase" , db:"admin"}]})

但代码失败并显示：

Exception in thread "main" com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='myuser', source='mydatabase', password=<hidden>, mechanismProperties={}}

我在这里缺少什么？
