Question

question > resulting > result 순으로 템플릿을 이동하고싶습니다.resulting > result에서 a href로 이동하면 아무 오류없이 원하는 내용 다 뜨는데 (null 없음)문제는 getmapping이나 postmapping으로 이동할때는 무조건 오류가 뜹니다..형식의 문제는 아닌거같은게 다른 페이지들에서는 잘 작동합니다.아래 오류 내용 첨부하겠습니다..처음 글 쓰는건데 온 구글을 뒤지고 gpt랑 집중면담해도 해결되는게 없어서 답답합니다 ㅠㅠ2023-05-29 22:01:22.660 ERROR 59424 --- [nio-8080-exec-5] org.thymeleaf.TemplateEngine : [THYMELEAF][http-nio-8080-exec-5] Exception
