도메인 오브젝트 만들어서 jackson으로 json데이터로 보내는데 json데이터까지는 문제 없이 만들어지는데 "cid can’t be null"이라는 오류 메세지가 옵니다. body에 제대로 값이 안들어가서 그런 것 같은데 httpEntity에 json데이터 넣고 httpPost객체에 setEntity 해서 보냈는데 이런 식으로 하면 안되는건가요?
Rest 서버라고 해서 위와같이 해 보았는데 다른 방법이나 해결책 있으시면 알려주시면 감사하겠습니다.

소스는 다음과 같이 작성하였습니다. ready를 위한 메소드 식으로 작성하였습니다.
다음은 log4j로 디버깅 모드를 실행한 결과입니다

로그를 찍어서 많이 지저분한 점 양해부탁드립니다.
해결했습니다~ 혹시 같은 문제를 겪고 계실 분들이 있을까 해서 해결법을 기록합니다.
문제는 x-www-form-urlencoded 방식으로 보내는 것이었는데 저의 경우에는 요청을 계속해서 json방식으로 보내는 것이었습니다.
VO객체의 toString()메소드를 http query 형식으로 하고 ByteArrayEntity클래스 인스턴스를 생성하여 Entity에 넣어주었더니 성공적으로 호출이 되었습니다. 감사합니다.
