Issue
Hi what trying to achieve is to get bearer token that submited from front end in java spring boot RESTApi controller and do another request using feign client to another microservices? here is what i do
image above is how i do my request from postman, and here is my controller code :
@Operation(summary = "Save new")
@PostMapping("/store")
public ResponseEntity<ResponseRequest<TransDeliveryPlanning>> saveNewTransDeliveryPlanning(
@Valid @RequestBody InputRequest<TransDeliveryPlanningDto> request) {
TransDeliveryPlanning newTransDeliveryPlanning = transDeliveryPlanningService.save(request);
ResponseRequest<TransDeliveryPlanning> response = new ResponseRequest<TransDeliveryPlanning>();
if (newTransDeliveryPlanning != null) {
response.setMessage(PESAN_SIMPAN_BERHASIL);
response.setData(newTransDeliveryPlanning);
} else {
response.setMessage(PESAN_SIMPAN_GAGAL);
}
return ResponseEntity.ok(response);
}
and here is how my service look like :
public TransDeliveryPlanning save(InputRequest<TransDeliveryPlanningDto> request) {
Future<List<PartnerDto>> initPartners = execs.submit(getDataFromAccount(transDeliveryPlanningDtSoDtoPartnerIdsSets));
}
public Callable<List<PartnerDto>> getDataFromAccount(Set<Long> ids) {
String tokenString = "i should get the token from postman, how do i get it to here?";
List<PartnerDto> partnerDtoResponse = accountFeignClient.getData("Bearer " + tokenString, ids);
return () -> partnerDtoResponse;
}
as you can see, in "tokenString" there i put a string that i questioned about, how do i get it to there from postman?
Solution
Although the suggested answers work, passing the token each time to FeignClient calls still not the best way to do it.
I would suggest to create an interceptor for feign requests and there you can extract the token from RequestContextHolder and add it to request header directly.
like this:
@Component
public class FeignClientInterceptor implements RequestInterceptor {
private static final String AUTHORIZATION_HEADER = "Authorization";
public static String getBearerTokenHeader() {
return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getHeader("Authorization");
}
@Override
public void apply(RequestTemplate requestTemplate) {
requestTemplate.header(AUTHORIZATION_HEADER, getBearerTokenHeader());
}
}
this way you have a clean solution for your issue
