스프링 2.5.5 프로젝트를 사용하는 Java를 시작하기에 처음입니다. Spring Annotation이 해결되지 않은 문제가 있습니다. $ {MSG}spring2 주석이 렌더링되지 않았습니다.

대단히 감사합니다.
Spring 2.5.6으로 프로젝트를 시작하는 것은 엉뚱한 일이다. 이 버전은 매우 오래되었고 (9 년!) 더 이상 유지 관리되지 않습니다. 최신 안정적인 Spring 버전을 사용하십시오. 자바 6 -> 자바 8, 서블릿 2.5 -> 서블릿 3.1, junit 3.8 -> junit 4.x. –
나는이 버전의 Spring을 사용하고있는 오래된 프로젝트를 유지해야만한다. 그래서 그것에 대해 배우고 싶다. – Diviner
