Using @RequestLine with Feign

Question

I have a working Feign interface defined as:

@FeignClient(\"content-link-service\")
public interface ContentLinkServiceClient {

    @RequestMapping(method = Req         


        

Answer 1

I wouldn't expect this to work.

@RequestLine is a core Feign annotation, but you are using the Spring Cloud @FeignClient which uses Spring MVC annotations.

Answer 2

Your @RequestMapping value looks ok, but you're likely should consider slightly rewriting it:

 @GetMapping(value = "/{trackid}/links")
 List<Link> getLinksForTrack(@PathVariable(name = "trackid") Long trackId);

Btw I did not succeeded with getting @RequestLine to work due to same error as yours.

Also for @ReactiveFeignClients Contract.Default() yields to following errors:

java.lang.IllegalStateException: Method MyClient#doStuff(String,String) not annotated with HTTP method type (ex. GET, POST)
Warnings:
- Class MyClient has annotations [Component, ReactiveFeignClient, Metadata] that are not used by contract Default
- Method doStuff has an annotation GetMapping that is not used by contract Default

and should be fixed like:

var MyClient = WebReactiveFeign.builder()
        .contract(new ReactiveContract(new SpringMvcContract()))
        .target(MyClient, "http://example.com")

Answer 3

Spring has created their own Feign Contract to allow you to use Spring's @RequestMapping annotations instead of Feigns. You can disable this behavior by including a bean of type feign.Contract.Default in your application context.

If you're using spring-boot (or anything using Java config), including this in an @Configuration class should re-enable Feign's annotations:

@Bean
public Contract useFeignAnnotations() {
    return new Contract.Default();
}
