springframework [/WEB-INF/spring/root-context.xml] 에러

안녕하세요. 주원이상감자입니다.

틀린 내용이 있다면 댓글로 알려주시면 감사하겠습니다.

개요

처음 이 증상을 접하게 된건,

정상적으로 운영중인 서비스에서 서비스를 재시작 하고나니 발생하였습니다.

기존 개발된 서비스들에서는 https://www.springframework.org/schema/beans/spring-beans.xsd' 를 사용했는데,

아무 문제가 없었지만 갑자기 문서를 읽는데 실패했다는 이슈가 발생하였습니다.

조치 (root-context.xml)

root-context.xml 이 문제라고 해서 이 파일을 열어 내용을 수정하였습니다.

아래 내용에 보면 "https://www.springframework.org/schema/beans/spring-beans.xsd" 부분에서 HTTPS가 아닌  "https://www.springframework.org/schema/beans/spring-beans.xsd" 로 바꾸면 조치가 가능합니다.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">
        <!-- https://www.springframework.org/schema/beans/spring-beans.xsd"> -->  
        <!-- Root Context: defines shared resources visible to all other web components -->
        <import resource="database/applicationContext.xml"/>

</beans>

 

결과

일단 Spring 홈페이지에 들어가서 해당 파일을 어떻게 사용하는지에 대해서 Doc를 확인하였습니다.

여기서도 HTTP를 사용하고 적혀있습니다.

https://docs.spring.io/spring-framework/docs/4.2.x/spring-framework-reference/html/xsd-configuration.html

40. XML Schema-based configuration

 

 

HTTP 로씁시다. ㅎ_ㅎ
