Hi, I saw there is an issue spring-cloud/spring-cloud-netflix#894 which add support for placeholders of value field.
But other field such as "headers" still not support placeholder.
Since sometimes we need set Authentication header, it is awesome if the value could be loaded from properties file.
@FeignClient("foo")
public interface FooClient{
@RequestMapping(value = "${my.special.placeholder}",
method = RequestMethod.GET,
headers = "${my.token}"
ResponseEntity getSomeData(s);
}
