Boa Tarde!! Poderia verificar estou com erro abaixo, já realizei todos os procedimentos do forum e não consegui resolver, em minha opnião o motivo o erro se deve ao conector mysql, no outro curso não estava aceitado a versão 5.1.3 tive que colocar o conector 8.0, mas como esse projeto esta no maven eu não sei como alterar.
