Pessoal.
Defini no meu applicationContext abaixo um bean para inicialização do meu placeholder conforme exemplo abaixo, mas no bean dataSource não estou conseguindo ler as variáveis do placeholder pois ele está interpretando as variáveis como string e está dando o erro também postado abaixo, poderiam me dar uma dica de como resolver este problema?
Muito obrigado.
