相关疑难解决方法(0)

我需要在我的spring security 3.0.5 Web应用程序中对用户进行解除身份验证(终止他们的会话),然后将重定向发送到另一个站点以通知他们注销.这在春天是否可行？如果是这样,执行这些任务的一般方法是什么？谢谢!

import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.logout.SimpleUrlLogoutSuccessHandler;

import com.dc.api.model.Users;

public class DCSimpleUrlLogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler{

    public void onLogoutSuccess(javax.servlet.http.HttpServletRequest request, 
            javax.servlet.http.HttpServletResponse response,
            Authentication authentication)
     throws java.io.IOException,
            javax.servlet.ServletException{
            Users user=null;
            Object principal = authentication.getPrincipal();
            if (principal instanceof Users) {
                user = (Users) principal;
                if(user.getType().equals(TEST)){
                    response.sendRedirect("LogoutServlet");
                }
            }
            response.sendRedirect("login.html");

}

}
