Sesión
Vamos a crear la sesión para cuando nos logueamos.
Creamos el paquete
com.tutosoftware.activity.util creamos la clase
SessionUtils
package com.tutosoftware.activity.util;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
public class SessionUtils {
public static HttpSession getSession() {
return (HttpSession) FacesContext.getCurrentInstance()
.getExternalContext().getSession(false);
}
public static HttpServletRequest getRequest() {
return (HttpServletRequest) FacesContext.getCurrentInstance()
.getExternalContext().getRequest();
}
public static String getUserName() {
HttpSession session = (HttpSession) FacesContext.getCurrentInstance()
.getExternalContext().getSession(false);
return session.getAttribute("username").toString();
}
public static String getUserId() {
HttpSession session = getSession();
if (session != null)
return (String) session.getAttribute("userid");
else
return null;
}
}
Filtro
Creamos el paquete
com.tutosoftware.activity.filter y en el la clase
AuthorizationFilter
package com.tutosoftware.activity.filter;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
@WebFilter(filterName = "AuthFilter", urlPatterns = { "*.xhtml" })
public class AuthorizationFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
// TODO Auto-generated method stub
try {
HttpServletRequest reqt = (HttpServletRequest) request;
HttpServletResponse resp = (HttpServletResponse) response;
HttpSession ses = reqt.getSession(false);
String reqURI = reqt.getRequestURI();
if (reqURI.indexOf("/login.xhtml") >= 0
|| (ses != null && ses.getAttribute("username") != null)
|| reqURI.indexOf("/public/") >= 0
|| reqURI.contains("javax.faces.resource"))
chain.doFilter(request, response);
else
resp.sendRedirect(reqt.getContextPath() + "/faces/login.xhtml");
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
}
