**I have declared properties in application properties-**
spring.data.mongodb.database=dbname
spring.data.mongodb.username=admin
spring.data.mongodb.password=*******
spring.data.mongodb.port=27017
spring.data.mongodb.host=192.168.0.2
登录凭据仍然正确，我收到了这个错误。异常验证MongoCredential也我得到了未分类的Mongo Db异常
请帮帮我！
根据#46934427，设置spring.data. mongoDB.验证数据库=admin可能会解决您的问题。
MongoDB中的默认数据库是test，因此，您可能正在尝试针对test数据库进行身份验证。切换到admin数据库（创建用户的常用位置）可能会解决您的问题。
你可以试试这个：
spring.data.mongodb.uri=mongodb://user:passwod@localhost/test?authSource=admin
Add user admin into your database.
Open installed folder and open the mongo.exe file and run below command :
use admin
db.createUser(
{
user: "admin",
pwd: "admin",
roles: [ { role: "userAdminAnyDatabase", db: "admin" },
{ role: "dbAdminAnyDatabase", db: "admin" },
{ role: "readWriteAnyDatabase", db: "admin" } ]
}
)
