Всем здрям!
Есть простое приложение на MVC Spring (Spring 2.0, Apache Tomcat 6.0.20).
Кусок файла настройки MVC для приложения:

Проблема в том, что не вызывается метод preHandle() класса HttpRequestInterceptor, кот. должен проверять залогинен ли сейчас юзер в системе или нет (если нет — то вызывать страницу авторизации SignIn). Не вызывается он только если я вбиваю в браузер строку /timesheetlist.htm, для /enterhours.htm — все Ок. Т.е. вызывается соответствующий сервлет для /timesheetlist.htm для последнего залогиненого юзера, хотя он сделал логаут (минуя вызов preHandle).
Приведу код для HttpRequestInterceptor, TimesheetListController (для просмотра данных), EnterHoursController (для ввода и записи новых данных):
HttpRequestInterceptor:
| Код |
public class HttpRequestInterceptor extends HandlerInterceptorAdapter
{
private String signInPage;
private ApplicationSecurityManager applicationSecurityManager;
/**
* Uses ApplicationSecurityManager to ensure user is logged in; if not,
* then user is forwarded to the sign-in page.
* @see ApplicationSecurityManager
*/
public boolean preHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler) throws Exception
{
System.out.println("HttpRequestInterceptor::preHandle()");
Employee employee = (Employee) applicationSecurityManager
.getEmployee(request);
if (employee == null)
{
System.out.println("HttpRequestInterceptor::preHandle(): null");
response.sendRedirect(this.signInPage);
return false;
}
System.out.println("HttpRequestInterceptor::preHandle(): not null");
return true;
}
public String getSignInPage()
{
return signInPage;
}
public void setSignInPage(String signInPage)
{
this.signInPage = signInPage;
}
public ApplicationSecurityManager getApplicationSecurityManager()
{

}
public void setApplicationSecurityManager(

TimesheetListController:

public static final String MAP_KEY = "timesheets";

{

.getEmployee(request);
List timesheets = timesheetManager.getTimesheets(employee
.getEmployeeId());
