Question

我正在使用JSF2来开展一个项目。我使用Spring安全性进行身份验证（访问，登录和注销），我的查看页面是xhtml。我的问题是退出后用户可以回到上一页并做好工作。我使用AuthenticationBean类登录＆amp; louout。另外，我将下面的命令添加到我的页面的标题，但没有任何改变！

meta http-equiv="Cache-control" content="public"
meta http-equiv="Cache-control" content="private"
meta http-equiv="Cache-control" content="no-cache"    
meta http-equiv="Cache-control" content="no-store"

豆子：

@ManagedBean(name = "authenticationBean")
@RequestScoped
public class AuthenticationBean {
    public String doLogin() throws ServletException, IOException {
        ExternalContext context = FacesContext
               .getCurrentInstance().getExternalContext();

        RequestDispatcher dispatcher = ((ServletRequest) context.getRequest())
               .getRequestDispatcher("/j_spring_security_check");

        dispatcher.forward(
            (ServletRequest) context.getRequest(),
            (ServletResponse) context.getResponse());

        FacesContext.getCurrentInstance().responseComplete();
        return null;
    }

    public String doLogout() {
        FacesContext.getCurrentInstance()
             .getExternalContext().invalidateSession();
        return "/login.xhtml";
    }
}
