원인

• mapper id가 다른 경우 (이 케이스가 많음)
  • - mapper파일에 <select id=''.. 에 id 과 DAO 파일의 매퍼 아이디가 다른경우 
       - ex ) <select id="getUserInfo"  와  sqlSessionTemplate.selectOne("userMapper.getUser",userSeq);
• mapper에 정의된 namespace 중복
  • mapper.xml 파일의 <mapper namespace="userMapper"> 가 중복되는지 체크
• mapper location 세팅 확인 - 경로가 잘 잡혔는지. (프로젝트 처음 세팅을 했는데 안되는 경우 이 부분 확인)
  • classpath*:static/mappers/**/*Mapper.xml 이부분   (*가 없는 경우 *를 추가)

나는 sqlmap 의 위치를 src/main/resources에 넣어야하는데 /src/main/webapp/resources 에 넣어 오류
