Foi dado esse erro após inserir JPAProductionConfiguration.class e comentar onStartup no ServletSpringMvc.java

Fala Wellington, tudo bem ?

A exception diz que não foi encontrado um bean do tipo DataSource, por isso não foi satisfeita uma injeção de dependencia.

Provavelmente está ocorrendo porque não está passando a propriedade spring.profiles.active, imagino que nesse caso, apontando o profile como dev. Apontamos o profile como dev na sobrescrita do método onStartup() da classe ServletSpringMvc, portanto o código não pode estar comentado.

Dê uma olhada nisso. Creio que já resolve. Espero ter ajudado. Abraço!

Olá Boa tarde, muito obrigado por ajudar ! Então ... mas para deployar no heroku devo comentar certo? isso nao faz com que no heroku o projeto nao funcione? pois o meu projeto no heroku so mostra essa tela com essa mensagem:

" Application error

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. "

Wellington, você provavelmente está usando o Tomcat correto ? Sim, é verdade no heroku o datasource a ser utilizado é o de produção e não e o de "dev". Logo você deve comentar ou excluir este código do onStartup e fazer o deploy da aplicação para o heroku utilizando o datasource "prod" e a aplicação conseguirá subir lá com as configurações do datasource correto.

No entanto ao fazer isso, a aplicação deixa de rodar localmente pois a mesma vai tentar subir utilizando o datasource "prod", o que não contém as configurações corretas para rodar no mysql.

O que você deve fazer é passar o mesmo parâmetro que antes você passava através desse método:

//    @Override
//    public void onStartup(ServletContext servletContext) throws ServletException {
//        super.onStartup(servletContext);
//        servletContext.addListener(RequestContextListener.class);
//        servletContext.setInitParameter("spring.profiles.active", "dev");
//    }

só que agora via argumento nas configurações do tomcat. Seleciona o servidor na aba "Servers" e tecla F3 que vai abrir a Overview do servidor, clica em "Open launch configuration" > "Arguments" > VM Arguments adiciona o argumento -Dspring.profiles.active="dev" ao final da lista de argumentos ok?

Como é só para desenvolvimento, da certo você ficar subindo o seu tomcat com este parâmetro, se houver necessidade você pode criar um servidor só para essa sua aplicação e deixar ele com esse parâmetro, mudar a porta do server, etc

Davi, obrigado por me ajudar a solucionar o problema.

Existe a possibilidade de definir o perfil pela inicialização do Spring?

Grande abraço!
