Struts에서 로그인(login) 처리하기. -> 세션(sessin) 얻어와서 sessio에 값 저장하기

 

/*

 * struts2에서 세션사용하기

 * 방법1)

 * - SessionAware를 implements 한다.

 * - Session메소드를 오버라이딩 하면 자동으로 세션객체가 파라미터 변수에

 *   저장된다.

 * - 파라미터 변수를 멤버변수 SessionMap 객체에 담아놓는다.

 *

 * 방법2)

 *     ActionContext cxt = ActionContext.getContext();

 *     Map<String, Object> session = ctx.getSession();

struts 에서 namespace 사용하기

struts action 정의 xml에서 namespace사용하기

struts.xml에서 여러개의 action을 정의하는 xml파일을 인클루드 할 수있다.

이렇게되면 중볻되는 name이 있을 수 있다. 그래서 namespace를 사용한다.

    사용방법은

     <package name="default" namespace="/aa" extends="struts-default">

    이렇게 defalult로 namespace="/"로 되어있던것을 namespace="/aa"로 바꿔준다.

    이렇게하면 action을 호출할 때 뷰 페이지(~~.jsp)에서 form 태그의 action="aa/logout.action" 이런식으로 주어야 한다.         

-->

    <package name="default" namespace="/aa" extends="struts-default">

        <action name="login"  class="hb.action.LoginAction" method="login">

              <!-- redirect로 이동시키기.

                         디폴트로 forwarding이다.

                       - type="dispatcher" 로 지정되어있다.

                         type="forwarding" 이 아니다. 

              -->

              <result type="redirect">/member.jsp</result>

              <result name="login">/login.jsp</result>

        </action>

        <action name="loginForm">

              <result>/login.jsp</result>

        </action>

        <action name="logout" class="hb.action.LoginAction" method="logout">

              <result>/logout.jsp</result>

        </action>

    </package>

</struts>
