java – identity. Viewexpiredexception after logout(); In JBoss seam
•
Java
After my authenticationfilter redirects to the login page, I want to exit to the user
That's why I put identity logout(); In my pre render method login In checkpermission (...) of XHTML
However, when the user logs in again, I get viewexpiredexception
My question is
1: If I don't execute identity logout();, Because the old user session still exists, the user logs in again 2: If I execute identity logout();, I will receive viewexpiredexception
AuthenticationFilter. java
public class AuthenticationFilter implements Filter { ..... public void doFilter(ServletRequest servletRequest,ServletResponse servletResponse,FilterChain filterChain) throws IOException,ServletException { HttpServletRequest httpRequest = (HttpServletRequest) servletRequest; HttpServletResponse httpResponse = (HttpServletResponse) servletResponse; HttpSession session = httpRequest.getSession(); User user = (User) session.getAttribute(Constants.LOGIN_USER); if (user == null) { session.setAttribute(Constants.MESSAGE_ID,MessageId.required_TO_LOGIN); String loginView = httpRequest.getContextPath() + Constants.LOGIN_PAGE; httpResponse.sendRedirect(loginView); } else if (!user.getRole().equals(Role.SYstem_ADMINISTRATOR)) { System.out.println("User Role : " + user.getRole()); session.setAttribute(Constants.MESSAGE_ID,MessageId.required_TO_ADMIN_ROLE); String loginView = httpRequest.getContextPath() + Constants.LOGIN_PAGE; httpResponse.sendRedirect(loginView); } else { filterChain.doFilter(servletRequest,servletResponse); } servletContext.log("Exiting the filter"); } public void destroy() { } }
login. xhtml
.... <f:event listener="#{LoginBean.checkPermission}" type="preRenderView" /> ....
LoginBean. java
@Scope(ScopeType.EVENT) @Name("LoginBean") public class LoginBean extends BaseBean { .... public boolean authenticate() { .... } public void checkPermission(ComponentSystemEvent event) { FacesContext context = getFacesContext(); ExternalContext extContext = context.getExternalContext(); String messageId = (String) extContext.getSessionMap().remove(Constants.MESSAGE_ID); if(messageId != null) { identity.logout(); addMessage(null,FacesMessage.SEVERITY_ERROR,messageId); } } }
Solution
Do not use identity logout(); In the prerenderview method In authenticationfilter, if you want to lock the current session and create a new session, do the following before passing the messageid
if(...) { session.invalidate(); session = httpRequest.getSession(true); .... } else if(...){ session.invalidate(); session = httpRequest.getSession(true); .... }
