Autowire JavaMailSender with spring-boot-starter-mail is not working at springboot 3.0.2??

[2dongyeop]

I encountered a problem while referring to Baeldung's posting.

The only difference from baeldung's posting is that I used spring-boot-starter-mail. Is there a solution?

Stack trace:

There are comments on #33452 showing how to do that. If you need some more help, please follow up on Stack Overflow.
