zkoss spring configuration

ZK OSS는 Direct RIA 프레임워크다.
Direct RIA가 몬지. ZK가 몬지는 담에 기회에 있으면 포스팅하기로 하고,
이번 포스트는 zkoss에서 스프링을 사용하기 위한 설정만 살펴보기로 하자.

스프링 설정하는 건 다들 아는 것일테고, 간단히 zkoss에서 스프링 빈을 사용하는 방법에 대해서만 살펴보기로 하자.

web.xml 파일내에서 가장 중요한 것은 리스너 두개의 순서다. !!!
이거 무시하면 띠바 겁내 헤롱거릴거다!
반드시
org.zkoss.spring.web.context.CoreContextListener 먼저 설정 해주고
org.springframework.web.context.ContextLoaderListener 는 나중에 설정해 줘야한다.


나머지는 가이드 문서에 나와있는데로 설정하면 별 문제 없다.

위와 같이 설정하면 zkoss에서 스프링 프레임워크를 마음 껏 사용할 수 있다.~~
