j2ee에서 쿠키 자동 로그인 실현
1. 사용하는 상수
package com.hydom.util;
public final class CommonConstants {
// session
public final static String SESSION_USER = "session_user";
/** cookie */
public final static String BROWSER_COOKIE_EMAIL = "HKPhotoUserEmail";
/** cookie */
public final static String BROWSER_COOKIE_PASSWORD = "HKPhotoUserPassword";
/** cookie 15 */
public final static int BROWSER_COOKIE_MAX_AGE = 15*24*60*60;
/** cookie */
public final static String BROWSER_COOKIE_AUTO_STATUS_NAME = "HKPhotoAutoLoginStatus";
/** cookie */
public final static String BROWSER_COOKIE_LOGIN_OUT_NAME = "HKPhotoLoginOut";
}
2. 필터
package com.hydom.filter;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.hydom.entity.User;
import com.hydom.service.IUserService;
import com.hydom.util.CommonConstants;
import com.hydom.util.pico.PicoContainer;
/**

* user session <BR>
* doFilter()<BR>
*
* @author [email protected]<BR>
* @date 2011-9-22<BR>
* @version 1.0 <BR>
*
*/
public class CookieLoginFilter extends BaseFilter {
//
@Override
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
Object object = request.getSession().getAttribute(
CommonConstants.SESSION_USER);
User cookieUser = null;
String email = null;
String password = null;
String autoStatus = null;
if (object == null) {
Cookie[] cookies = request.getCookies();
if (cookies != null && cookies.length > 0) {
// System.out.println("cookies.length=" + cookies.length);
for (int i = 0; i < cookies.length; i++) {
Cookie cookie = cookies[i];
// Cookie "HKPhotoUserEmail"
if (CommonConstants.BROWSER_COOKIE_EMAIL.equals(cookie
.getName())) {
email = cookie.getValue().trim();
}
// Cookie "HKPhotoUserPassword"
if (CommonConstants.BROWSER_COOKIE_PASSWORD.equals(cookie
.getName())) {

}
// Cookie "HKPhotoAutoLoginStatus"
if (CommonConstants.BROWSER_COOKIE_AUTO_STATUS_NAME
.equals(cookie.getName())) {
autoStatus = cookie.getValue().trim();
}
}
if (autoStatus!=null&&autoStatus.equals("1")) {
if (email != null && password != null && email.length() > 0
&& password.length() > 0) {
cookieUser = new User();
cookieUser.setEmail(email);
cookieUser.setPassword(password);
// System.out.println("email=" + cookieUser.getEmail());
// System.out.println("password="
// + cookieUser.getPassword());
IUserService userService = PicoContainer.PICO
.getComponent(IUserService.class);
cookieUser = userService.validLogin(cookieUser);
if (cookieUser != null) {
// user session
request.getSession().setAttribute(
CommonConstants.SESSION_USER, cookieUser);
} else {
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
}
}
3.web.xml 설정 쿠키 로그인 필터
<!-- cookie -->
<filter>
<filter-name>cookie-login-filter</filter-name>
<filter-class>com.hydom.filter.CookieLoginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>cookie-login-filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
4. 사용자가 로그인한 경우
public class LoginAction extends BaseAction {
private static final long serialVersionUID = 1L;
private String email = null;//
private String password = null;//
private boolean autoLoginStatus = false;
public boolean getAutoLoginStatus() {

}

}

this.password = password;
}
//
private IUserService userService = PicoContainer.PICO
.getComponent(IUserService.class);
@Override
public String execute() throws Exception {
try {
//
String message = checkAndFilterUsersInfo();
;
User user = null;
if (message == null) {
user = new User();
user.setEmail(this.email);
user.setPassword(this.password);
user = userService.validLogin(user);
}
//
StringBuilder msg = new StringBuilder();
msg.append("{");
if (user != null) {
super.getSession().setAttribute(CommonConstants.SESSION_USER,
user);
msg.append("msg:'success'").append(",");
msg.append("userName:'").append(user.getUserName()).append("'");
if (autoLoginStatus) {
//
addCookieingUserToResponse(user);
}else{
removeCookieingUserInResponse();
}
} else {
if (message == null) {
msg.append("msg:' '");
} else {
msg.append("msg:'").append(message).append("'");
}
}
msg.append("}");
ajaxJson(msg.toString());
} catch (Exception e) {

}
return null;
}

5. 종료
public class LogOutAction extends BaseAction {

// cookie
