Struts2 #03(Action클래스 : 여러 파라미터값을 vo객체에 한번에 담기(setter))

2013. 5. 4. 13:52

클라이언트에서 submit된 파라미터를 vo객체에 한번에 setter하기.
; 하나씩 setter메소드를 호출해도 되지만 vo객체를 선언하고 담으면 편리하다.
; action클래스에서 인터페이스 Preparable, ModelDriven을 구현한다.

1) insert.html / success.jsp / error.jsp
2) MemberAction.java ( test.action 패키지 )
3) MembersDao.java ( test.dao )
4) MembersVo.java ( test.vo )
5) Mybatis 관련 orm파일
    5-1) SqlsessionFactoryService.java
    5-2) MembersMapper.xml
    5-3) mybatis-config.xml
6) example.xml ( struts action매핑 xml )
