我想与在docker中运行的MongoDB数据库建立连接。应用程序似乎启动没有任何问题，但当我尝试调用任何请求时，如简单的GET：
localhost:8082/devices根据配置的不同，我收到两个不同的错误：
具有以下属性：
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.host=interviewTest
spring.data.mongodb.port=27017
spring.data.mongodb.username=mongoadmin
spring.data.mongodb.password=secret
server.port=8082
spring.data.mongodb.uri=mongodb://localhost:27017
spring.data.mongodb.database=interviewTest我正在接收：
com.mongodb.MongoQueryException: Query failed with error code 13 and error message 'command find requires authentication' on server localhost:27017对于不同配置的application.properties：
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.port=27017
spring.data.mongodb.username=mongoadmin
spring.data.mongodb.password=secret
server.port=8082
spring.data.mongodb.database=interviewTest
spring.data.mongodb.uri=mongodb://mongoadmin:secret@localhost:27017/interviewTest?retryWrites=true&w=majoritycom.mongodb.MongoCommandException: Command failed with error 18 (AuthenticationFailed): 'Authentication failed.' on server localhost:27017. The full response is { "ok" : 0.0, "errmsg" : "Authentication failed.", "code" : 18, "codeName" : "AuthenticationFailed" }我创建了MongoDB docker容器，如下所示：
docker run -p 27017-27019:27017-27019
--name mongo
-e MONGO_INITDB_ROOT_USERNAME=mongoadmin
-e MONGO_INITDB_ROOT_PASSWORD=secret
-e MONGO_INITDB_DATABASE=interviewTest
-d mongopom.xml

MONGO_INITDB_ROOT_USERNAME, MONGO_INITDB_ROOT_PASSWORD
These variables, used in conjunction, create a new user and set that user's password. This user is created in the admin authentication database and given the role of root, which is a "superuser" role.因此，如果我正确地理解了这一点，那么我的基本用户mongoadmin的角色没有问题。
我试图组合多个配置选项，但没有产生理想的效果。对于如何通过MongoDB配置和建立连接来解决该问题，我将不胜感激。

我找到了一个有@Valijon支持的解决方案。原来我们不能使用ROOT_USERNAME来读出数据库。我们的root用户可以用来创建新的数据库、集合和新用户。解决方案真的很简单。我们应该使用以下命令打开docker
docker exec -it mongo bash和标志-it，这意味着它将是一个交互式终端，毕竟，我们将能够与我们的容器交谈。毕竟，我们使用类似的mongo命令来建立具有root管理员凭据的身份验证。
mongo -u mongoadmin在下一个命令行中，我们将传递password。
毕竟，我们使用的是命令：
use interviewTest为了选择数据库，我们将在其中添加一个自定义用户。
现在，我们可以使用自定义密码、用户名和角色键入已准备好的脚本：
db.createUser({user: "testUser", pwd: "pwd", roles : [{role: "readWrite", db: "interviewTest"}]});现在一切正常，我们可以使用我们的数据库而不会出现身份验证错误。
