Quando tento rodar o SpringDataApplication dá essa exceção : 

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Oi Daniel! Tudo certo?

Desculpe pela demora em obter um retorno.

Acredito que esteja faltando um @Entity na sua classe Cargo, já que o Spring diz que ela não está mapeada. Só não ficou muito claro se esse é o único problema. Tenta adicionar a anotação e avisa o que acontecer por aqui.

Espero ter ajudado!

Abraços e bons estudos!
