Ola pessoal!
Estou começando com Spring e estou com uma duvida.
Estou utilizando Spring Boot e queria configurar uns parametros fixos em minha aplicação. Mas não queria fazer direto no codigo conte, gostaria de de utilizar o application.properties. Tentei criar uma classe aqui com @Configuration. Mas sío da erro. Alguem tem alguma exemplo da forma correta de fazer isso.
Olá!
Como você está tentando fazer?
Se você fizer assim no seu código java:
@Value("${meu.teste}") private String nomeDoParametro;
e definir seu application.properties assim:
meu.teste=teste
ele irá pegar o valor ‘teste’ na variável ‘nomeDoParametro’
_Um dica: Se for fazer isso não use pra salvar senhas, código, etc, que serão privados na aplicação, pois o ‘application.properties’ fica disponível para qualquer um que tenha acesso ao servidor mesmo depois do código compilado.
Eu estou fazendo assim mesmo. Mas ao carregar a aplicação da uma mensagem que não conseguir instanciar o Bean com o nome da minha classe.
Tem como postar a mensagem de erro e/ou um trecho do código aqui?

Acho que o erro ta na hora que tu ta injetando (Autowired) essa classe. (Acho que pra te ajudar só tu postando ela aqui e onde tu ta chamando ela, e outra, ela ta anotada com @Component?)
Valeu cara erra isso mesmo.
Eu estava usando @Configuration troquei por @Component e deu certo.
Obrigado
