Description
I want to set the Content-Type header programatically. When I try this happens:
Caused by: feign.codec.EncodeException: Invalid mime type "{Content-Type}": does not contain '/'

@FeignClient("x")
public interface XClient {
@RequestMapping(value = "/api/something/{id}", method = POST)
void x(@RequestHeader("Content-Type") String contentType, @PathVariable("id") Integer id,
@RequestBody InputStream inputStream);
}
I ended up having to set a X-Content-Type2 header and setting up one of these:
@Bean
public RequestInterceptor contentTypeFilter() {
return (req) -> {
req.header("Content-Type", req.headers().get("X-Content-Type2").iterator().next());
};
}
I am using:
spring-cloud-netflix-core-1.2.5.RELEASE.jar
