memberService에서 정의한 MemberDTO파라미터랑 뭔가 매칭이 되지 않고 있는듯하네요 확인해야 할부분 1) select *을 빼고 컬럼명 모두 적는다2)resultMap에서 정의한 파라미터 이름들이 테이블에 모두 존재하고 오타가 있는지 확인한다3) resultMap에서 정의한 파라미터 이름들이 MemberDTO에 모두 존재하고 오타가 있는지 확인한다 그리고 초보자 이신것은 이해하지만저번글도 그렇고 애러매세지를 주루룩 나열해서 봐주세요는 좋은 방법이 아닙니다애러 보는법부터 시작하시는게 어떨까요

resultType&#61;&#34;int&#34; resultMap&#61;&#34;userMap&#34; !?!?파라미터 자료형 선언으로 해야할거 같은데요? 해당 내용 공식문서에요 참고하세요 https://mybatis.org/mybatis-3/ko/sqlmap-xml.html

Mux · Answer

MemberDTO라는 클래스를 찾을 수 없다고 합니다.Mybatis에 MemberDTO라는 Alias(예명) 역시 없다고 합니다. MemberDTO 클래스에 가셔서 &#64;Alias(&#34;MemberDTO&#34;)를 추가해보시는게 어떠신가요&#64;Alias(&#34;MemberDTO&#34;) public class MemberDTO { ... } * Mybatis SessionFactory를 설정하실 때, AliasPackage를 등록해야됩니다.* Mybatis setTypeAliasesPackage를 검색해보시는 것을 추천드립니다.

장쭌 · Answer

추출하고자 하는 데이터를 우선 생각하시고 그에 맞는 resultType 또는 resultMap을 사용하셔야 할 것 같습니다. select count(*) from Table;이면 숫자가 return 되는데 현재 개발하신 부분에 resultType도 있고, resultMap도 있습니다.

resultMap 사용 하고 싶은데 왜 이런 오류가 나올까요ㅠㅠ
