Put request doesn't get to my controller by feign client, getting 415 status code

Question

this is my feign client code

@RequestLine("PUT /merchants/{merchantId}")
@Headers("Content-Type: application/json")
MerchantDTO updateMerchant(@Param("merchantId") Long merchantId, PutMerchantDTO putMerchantDTO);

which is called in some requestFactory class. And this one is my controller code

@PutMapping(value = "/merchants/{merchantId}")
ResponseEntity<MerchantDTO> updateMerchant(@RequestBody @NotEmpty PutMerchantDTO updateMerchantRequest, @PathVariable("merchantId") final Long merchantId) {

    return ResponseEntity.ok(merchantUpdateMapper.toDtoMerchant(merchantUpdateService.processUpdate(merchantUpdateMapper.toDomain(updateMerchantRequest, merchantId))));
}

Can somebody Please tell me why I'm getting 415 when doing the put request with this feign Client to my controller?

Answer 1

remove @Headers and in @PutMapping add consumes = "application/json"

Answer 2

Not sure about the reason but Removing lines @Headers("Content-Type: application/json")

Answer 3

@PutMapping(value = "/merchants/{merchantId}") you write the same line like you specified in feign client

and change @Param("merchantId") to @PathVariable("merchantId")

Answer 4

Did you add the

@EnableFeignClients annotation

in main class?
