CannotGetMongoDbConnectionException: Failed to authenticate to database

In the replica-set Mongo Shell, use products;db.auth('worker'.'a*******6'); is alright, but in spring-data-mongondb, I encountered the following problem:

Exception in thread "main" org.springframework.data.mongodb.CannotGetMongoDbConnectionException: Failed to authenticate to database [products], username = [worker], password = [a*******6]
