Using @Headers with dynamic values in Feign client + Spring Cloud (Brixton RC2)

Question

Is it possible to set dynamic values to a header ?

@FeignClient(name="Simple-Gateway") interface GatewayClient {     @Headers("X-Auth-Token: {token}")     @RequestMapping(method = RequestMethod.GET, value = "/gateway/test")         String getSessionId(@Param("token") String token);     } 

Registering an implementation of RequestInterceptor adds the header but there is no way of setting the header value dynamically

@Bean     public RequestInterceptor requestInterceptor() {          return new RequestInterceptor() {              @Override             public void apply(RequestTemplate template) {                  template.header("X-Auth-Token", "some_token");             }         };     }  

I found the following issue on github and one of the commenters (lpborges) was trying to do something similar using headers in @RequestMapping annotation.

The solution is to use @RequestHeader annotation instead of feign specific annotations

@FeignClient(name="Simple-Gateway") interface GatewayClient {         @RequestMapping(method = RequestMethod.GET, value = "/gateway/test")     String getSessionId(@RequestHeader("X-Auth-Token") String token); }

The @RequestHeader did not work for me. What did work was:

@Headers("X-Auth-Token: {access_token}") @RequestLine("GET /orders/{id}") Order get(@Param("id") String id, @Param("access_token") String accessToken);
