스프링(spring) - *.do 액션에 대한 에러

Question

안녕하세요.&#34;스프링 퀵 스타트 책&#34;을 보며 게시판을 만들기 따라 하고 있습니다. (325-345p 실습을 따라하다 나온 에러) 실습 내용은 spring mvc DispatcherServlet, Controller을 사용하는 예제입니다.실습을 다 따라하고 톰켓을 실행시키면 jsp접근은 정상적으로 되는데 *.do 액션에 대해서만 아래와 같은 에러가 납니다. web log java.lang.NoSuchMethodError:

Intellij를 사용중입니다. 코드 : https://github.com/MinSooNam/Spring-Quick-Start.git

https://stackoverflow.com/questions/35108637/java-lang-nosuchmethoderror-org-springframework-util-reflectionutils-clearcache springframework.util.ReflectionUtils.clearCache() 메소드가 없다는거 같은데 스프링 버전등을 확인해 보시면 되지 않을까 합니다. 지금 다시 보니 spring-core 라이브러리가 없네요.

아래와 같이 추가되어 있으면 안되는 걸까요? pom.xml - 처음에 프로젝트 생성 할 때 properties와 dependencies값들이 하나도 없어서 왜그런지 궁금도 합니다. 4.0.0 com.springbook.biz BoardWeb 1.0-SNAPSHOT com.h2database h2 1.4.196 org.aspectj aspectjrt 1.6.10 org.aspectj aspectjweaver 1.8.12 org.springframework spring-jdbc 4.1.4.RELEASE commons-dbcp commons-dbcp 1.4 javax.servlet jstl 1.2

antop · Answer

그 메서드는 4 버전에는 없고 5 버전에 존재하는 메서드네요스프링 라이브러리 간 버전 확인해보세요 https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/util/ReflectionUtils.htmlhttps://docs.spring.io/autorepo/docs/spring-framework/4.1.4.RELEASE/javadoc-api/org/springframework/util/ReflectionUtils.html

정말 감사합니다ㅠㅠ코드에서는 문제가 안보였는데 IDE 설정까지 찾아보니 스프링 버전이 상이한 버전이 있었습니다.정확히 문제를 몰라 이것저것 헤매고 있었는데 키워드를 주셔서 감사합니다.
