Fala aí Cristiano, tudo bem? Acho que o problema está na versão no MySQL, apenas para concluir o curso não consegue instalar e utilizar a versão 5.6.x?

O problema é em relação a conexão segura, essa versão do MySQL habilita por padrão o SSL.

Você pode tentar desabilita-lo ou voltar a versão.

Espero ter ajudado.

Matheus, continua sem funcionar. Alguma dica?

Consegui instalar o MySql 5.7, entretanto, o erro continua o mesmo. Vou colocar aqui os logs. Peço ajuda, pois consegui um acesso especial alegando que esta versão resolveria o problema, mas nada aconteceu. Obrigado.

Fala aí Cristiano, tudo bem? Bom, como faz muito tempo que não mexo com MySQL, acho que a versão 5.7 talvez venha com o ssl ativado por padrão.

Tente adicionar useSSL=false na frente do comando para rodar o .jar:

ou need either to explicitly disable SSL by setting useSSL=false

Pode ser que resolva.

Referente ao último log que você mandou, o problema é porque você não passou a senha do seu usuário no MySQL e o mesmo está travado para conexões sem informar o password.

Access denied for user 'root'@'localhost' (using password: NO) at

Espero ter ajudado.

Obrigado Matheus pelo suporte.

Re-tentei rodar o arquivo com suas dicas mas nada aconteceu.

O comando que havia executado para colocar o último log passava a senha do root "java -jar cdcreact-1.0.0-SNAPSHOT.jar -Dspring.datasource.password=root".

O Mysql 5.7 já traz desabilitado o SSL: mysql> SHOW VARIABLES LIKE '%ssl%'; +---------------+----------+ | Variable_name | Value | +---------------+----------+ | have_openssl | DISABLED | | have_ssl | DISABLED | | ssl_ca | | | ssl_capath | | | ssl_cert | | | ssl_cipher | | | ssl_crl | | | ssl_crlpath | | | ssl_key | | +---------------+----------+ 9 rows in set (0.00 sec)

Estou vendo os fóruns e pela minha dedução, o arquivo .jar está sendo problema para várias pessoas. Até comentaram que o curso está sendo versionado.

Vou fazer o curso aqui por alto mesmo pois esta conta é corporativa e tenho meta para bater.

Muito obrigado pela atenção e apoio. att

Beleza Cristiano, termina o curso usando a API do Heroku.

Já posso te dar um spoiler que o mesmo está sendo regravado e atualizado, porém, sem data de publicação.

Abraços e bons estudos.

Obrigado!!!

Abraços e bons estudos.
