Feign: IllegalStateException: Method has too many Body parameters

[shivamsingh]

Request method:

@RequestMapping(method = RequestMethod.POST, value = "/backend/tokenCheck")
    @Headers({HeaderConstants.REQUEST_ID + " {requestId}"})
    AuthResponseDto checkToken(AuthRequestDto authRequestDto, @Param("requestId") String requestId);

Can you please tell me how to use request body and dynamic headers at the same time?

Thanks a lot.

A few things here you may want to double check.

First, you are mixing Feign and Spring annotations. I suggest @Param for @RequestParam, this is the most likely cause for that exception.

Next, annotation values must be literals. Your use of a constant in the @Headers will not work. The value will not be resolved and will result in the header not being constructed appropriately. An alternative way to accomplish this is to use the @RequestHeader annotation. Give those a try.

Were you able to get this resolved?
