I have a FeignClient like this
@RequestLine("POST /enroll")
@Headers({ "header1: {header1}", "header2: {header2}", "Content-Type: application/json" })
ResponseDto enroll(@Param("header1") String header1,@Param("header1") String header1, RequestDto requestDto)throws MyCustomException;
` I am not using spring cloud netflix. But I am keep getting the below exception.
Caused by: java.lang.IllegalStateException: Body parameters cannot be used with form parameters.

I am instantiating my client like this.
return Feign.builder()
.encoder(new JacksonEncoder())
.decoder(new JacksonDecoder())
.logger(new Slf4jLogger())
.logLevel(Logger.Level.FULL)
.target(RegularFeignClient.class, url);
Wow this a tricky one. The order of parameters matter here.
@RequestLine("POST /enroll")
@Headers({ "header1: {header1}", "header2: {header2}", "Content-Type: application/json" })
ResponseDto enroll(RequestDto requestDto, @Param("header1") String header1,@Param("header1") String header1)throws MyCustomException;
This works!!!
Thanks to my senior developer. He found it.
