• MaBatis에서는 Mapper XMl 파일의 namespace 속성이 인터페이스 이름과 정확하게 일치하여야 하는데 namespace 를 작성하지 않아서 발생하는 오류였다

<mapper namespace="com.example.project01.mapper.ProductMapper">
    <select id="product_list" resultType="product">
        select pid, img, name, cat, stk, price
        from product
    </select>
</mapper>

 

• 위와 같이 namespace를 추가해주니 동작하는 모습을 확인할 수 있었다.
