ConvidadoController required a bean of type ConvidadoRepository that could not be found

Boa noite,

Ao tentar seguir a aula 02 Configurando Spring Boot Data JPA estou me deparando com o seguinte erro:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field repository in br.com.springboot.listavip.ConvidadoController required a bean of type 'br.com.springboot.repository.ConvidadoRepository' that could not be found.


Action:

Consider defining a bean of type 'br.com.springboot.repository.ConvidadoRepository' in your configuration.

Todos os passos foram seguidos exatamente como a aula indicou, tentei diversas versões do spring boot, porém sem sucesso. Segue meus arquivos:
