baharda özellik dosyası dışında harita oluşturmayı kolaylaştırır.

Question

İlkbahar 4 kullanıyorum. Özellik dosyamdan fasulye olarak bir harita oluşturmak istiyorum. Birkaç örnekle karşılaştım ve Ortam'ın @PropertySource tarafından belirtilen özellik dosyasını tuttuğunu anladım. Bu yüzden aşağıdakine benzer bir şey yazdım, ama onun değil, fasülyenin yaratılmasında doğru değil. Biri bana doğru yönde işaret edebilir

mülkiyet dosyası:

abc=xyz 

bca=ppp 

acs=pkl 

Mülkiyet dosya okuyucu:

@Configuration 
@PropertySource("classpath:flash.properties") 
public class FlashConfig { 

    @Autowired 
    private Environment env; 

    @Bean 
    public String getProperty(String key) { 
     if (env.containsProperty(key)) { 
      return env.getProperty(key); 
     } else { 
      String msg = " flash property not found for the key: " + key; 
      throw new InternalServerErrorException(CPContractUtil.getProblemDetail(
        CPContractExceptionCodes.INTERNAL_SERVER_ERROR, msg)); 
     } 
    } 

}
