Я не могу остановить доступ пользователей к странице, например, приветствовать.jsp, когда он не находится в сеансе, пожалуйста, помогите мне в внедрении перехватчика входа. вот мой код. Все, что я хочу сделать, - это когда пользователь входит в систему с его идентификатором пользователя, проверяет, находится ли он в сеансе, если он находится в сеансе, пусть он получает доступ к любому другому ресурсу, перенаправляет пользователя на «somePage». ТИАПерехватчик входа Struts2 не работает
