"Accessing data with MySQL" guide does not work

See original GitHub issue

Following the steps in https://spring.io/guides/gs/accessing-data-mysql/ to the letter, the application fails to start with the following error:

Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

Presumably, some configuration is missing. Or Spring boot is broken.
