WebService 개발 실례 (Xfire + Spring + Hibernate)

본문 발췌: http://blog.csdn.net/caok/archive/2008/12/29/3637734.aspx
 
 
    Xfire 1.2.6, spring 2.0, hibenate 3.0 관련 라 이브 러 리 및 관련 데이터 베 이 스 를 다운로드 하 는 jdbc 드라이브 가 필요 합 니 다.본 논문 의 관련 내용 은 my eclipse 5.1 에서 완성 되 었 다.
 
하나           먼저 웹. xml 에 xfire 및 spring 지원 에 관 한 내용 을 추가 합 니 다. 다음 과 같 습 니 다.
