For my apps I have ConfigServer that serves application.yml properties. I added new @Value to my app and new properties for yml:
@Value("${sms-service.oauth-token}")
private String OAUTH_TOKEN;
@Value("${sms-service.proxy-address")
private String PROXY_ADDRESS;
in yaml:
sms-service:
oauth-token: xxx
proxy-address: https://api.com/
It read all other properties but not it. I saved this yaml file, commited it and nothing.
