[Help] Have any idea about global config path

Question: Is there a global config for path
Reason: Could some day v1 would be changed to v2 v3 vn(use an external tomcat deploy under different dir)....

feign comsumer:
Correct:

@FeignClient(name = "product-server",  path = "v1")
@Component
public interface ProductService {
    @RequestMapping(value = "getProduct")
    String getProduct();
}

Can not reach, hope there have a global config can set:

@FeignClient(name = "product-server")
@Component
public interface ProductService {
    @RequestMapping(value = "getProduct")
    String getProduct();
}

May someone would suggest use a property variable(like below), but... It's an old project, I do not want to modify it.

@FeignClient(name = "product-server", path = "${product-server.context-path}")
@Component
public interface ProductService {
    @RequestMapping(value = "getProduct")
    String getProduct();
}

product-server setting applications.yml

spring:
  application:
    name: product-server
server:
  port: 9999
  context-path: /v1
...
eureka:
  client:
    serviceUrl:
      defaultZone: xxx
...

No repository file or test is named. Start by tracing how the @FeignClient path is resolved and reviewing the product-server context-path in application.yml; done means establishing whether a global path setting can be supported without changing each interface.
