[Spring] Tomcat과 Maven의 연동에 따른 ContextLoaderListener를 찾지 못하는 문제

처음 Spring을 적용해볼까 하고 시작하다 보면 다음과 같은 오류가 발생하기도 합니다.

 

  현상

영문버전에서는 아래와 같이

심각: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener

한글버전에서는 아래와 같이

심각: 클래스 [org.springframework.web.context.ContextLoaderListener]의 애플리케이션 리스터를 설정하는 중 오류 발생

발생하기도 합니다.

 

전문은 아래와 같습니다. (한글버전)

  이유

Update Project Configuration 시 Maven 라이브러리 경로가 삭제되어 발생하는 문제

 

  해결방법

1. 설정 오픈

 > eGovMobile (프로젝트) 선택 → 메뉴의 [Project] 선택 → [Properties] 선택

 또는

 > eGovMobile (프로젝트) 우클릭 → [Properties]

 또는

 > eGovMobile (프로젝트) 선택 → Alt + Enter

 

eGovMobile (프로젝트) 선택 → 메뉴의 [Project] 선택  → [Properties] 선택

eGovMobile (프로젝트) 우클릭

2. Deployment Assembly → [Add...] → Java Build Path Entries → [Next] → Maven Dependencies → [Finish] →

Deployment Assembly > [Add] 버튼 클릭 > Java Build Path Entries > [Next] 버튼 클릭 > Maven Dependencies 선택 > [Finish] 버튼 클릭
