spring cloud - get server name for feign client from application properties

Question

I have two microservices demo-cartservice and demo-feignclient where the demo-feignclient fetches resources from demo-cartservice

In both projects I set server.servlet.context-path=/demo/api/ in application.properties

The Feign client proxy uses the hardcoded server name for demo-cartservice

@FeignClient("demo-cartservice/demo/api")
@RibbonClient("demo-cartservice/demo/api")
public interface DemoCartServiceProxy 
{
    @GetMapping("/carts/{cartId}")
    public Cart getCart(@PathVariable("cartId") long id);
}

This works fine.

Is there a way to read the server alias from application.properties as well, like so:

@FeignClient("${cartservice-alias}/${servlet-context}")
@RibbonClient("${cartservice-alias}/${servlet-context}")
public interface DemoCartServiceProxy 
{
    @GetMapping("/carts/{cartId}")
    public Cart getCart(@PathVariable("cartId") long id);
}

In application.properties of the demo-feignclient project I would like to have

server.servlet.context-path=/demo/api/
cartservice-alias=demo-cartservice

Thanks for the help

Answer 1

Sorry should have checked the docs first. After setting

feign.name=demo-cartservice/demo/api

in application.properties of demo-feignclient this works:

@FeignClient(name="${feign.name}")
@RibbonClient(name="${feign.name}")
public interface DemoCartServiceProxy 
{
    @GetMapping("/carts/{cartId}")
    public Cart getCart(@PathVariable("cartId") long id);
}
