parece que seu banco precisa de senha.

solução!

Boa tarde Pedro,

Essa linha da stack de erro:

Caused by: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: NO)

Significa que não foi possível conectar no banco de dados MySQL do localhost, com usuário root e sem senha.

Quando você realizou a instalação do MySQL definiu senha de acesso para o root? Parece que sim, e nesse caso essa senha deve ser colocada na sua classe que tem os dados da conexão com o banco.

Verifique isso e nos de um retorno, abraço.

Obrigado a todos, era só colocar o password no arquivo persistence, é que eu fiquei assustado com o tanto de erro que deu hahaha.
