java.lang.ClassNotFoundException: org.springframework.web.filter.CharacterEncodingFilter 오류 발생 해결 방법

톰캣에서 Spring을 적용할 때 아래와 같은 오류가 발생하는 경우가 있다.

해결 방법

제일 먼저 해본 방법은 위의 CharacterEncodingFilter 클래스를 포함한 jar가 빠졌는지 확인했었다. 

확인해본 결과 포함이 되어 있어서 어떤 문제인지 확인하는데, 시간이 많이 소요되었다. 

아래 방법으로 해서 해결할 수 있었다. 

 

.

 

pom.xml에 아래 내용을 추가한다. 

 

        <properties>

               <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

               <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

        </properties>

 

그 뒤에 톰캣을 재기동 했더니, 정상적으로 서비스가 수행되었다.
