    Caused by: com.mongodb.MongoCommandException: Command failed with error 18 (AuthenticationFailed): 'Authentication failed.' on server 192.168.0.2:27017. The full response is { "ok" : 0.0, "errmsg" : "Authentication failed.", "code" : 18, "codeName" : "AuthenticationFailed" }

**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

登录凭据正确，但我仍收到此错误.

请帮帮我！
