[Struts2] 스트러츠를 이용한 간편 로그인 - Simple Login Example

스트러츠를 이용한 간편 로그인 - Simple Login Example

- ActionSupport 와 SessionAware를 이용한다

1. struts.xml

<package name="login" namespace="/" extends="struts-default"> <action name="loginform" class="parkunity.action.header.LoginAction" method="loginform"> <result name="success">/WEB-INF/view/login/login.jsp</result> </action> <action name="login" class="parkunity.action.header.LoginAction"> <result name="redirect" type="redirect">${url}</result> </action> <action name="logout" class="parkunity.action.header.LoginOutAction" method="logout"> <result name="success" type="redirect">/index</result> </action> </package>

2. LoginAction.java

public class LoginAction extends ActionSupport implements SessionAware{ private String password; private String email; private String name; private String user_id; private String url; private int idx; private SessionMap<String,Object> session; public String loginform() { return "success"; } @Override public void setSession(Map<String,Object> session){ this.session = (SessionMap<String,Object>)session; } public String execute() throws Exception{ session.put("id", user_id); url = "index"; return "redirect"; } //getter, setter 생략  

- setSession을 구현해야 한다

- session.put("id", user_id); 을 이용하여 session에 등록한다

- execute() 안에 validation 체크에 관한 함수를 작성 해도된다.

3. LogoutAction.java

public class LoginAction extends ActionSupport implements SessionAware{ private String password; private String email; private String name; private String user_id; private String url; private int idx; private SessionMap<String,Object> session; public String loginform() { return "success"; } @Override public void setSession(Map<String,Object> session){ this.session = (SessionMap<String,Object>)session; } public String execute() throws Exception{ session.put("id", user_id); url = "index"; return "redirect"; }  

- session.remove("id") 를 통해 세션을 해제한다

4. main.jsp

<ul id="naviList"> <c:if test="${!empty sessionScope.id }"> <li class="naviItem">${sessionScope.id } 환영합니다.<a href="logout">(logout)</a> </li> </c:if> <li class="naviItem"><a class="naviItemLink" href="about">About</a></li> <li class="naviItem"><a class="naviItemLink" href="creator">Creator</a></li> <li class="naviItem"><a class="naviItemLink" href="contactus">Contact us</a></li> <li class="naviItem"><a class="naviItemLink" href="signup">Sign up</a></li> <li class="naviItem"><a class="naviItemLink" href="loginform">Login</a></li> </ul>
