IllegalStateException: Method has too many Body parameters

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.

I had this issue because I was mixing Feign annotations with Spring annotations. In the particular case, I was using @HeadersMap, which I replaced with @RequestHeader to make it work.
