session.user.name
i właśnie nie jestem pewien czy jest to odpowiedni sposób. Również mógłbym to zrobić poprzez dodanie obiektu z sesji najpierw do modelu
model.addAttribute("user", session.getAttribute(user));i wtedy mógłbym po prostu odnosić się do obiektu user, a nie sesji. Albo np. te alerty. Utworzyć np. tylko jeden alert, a do modelu podawać jakiej klasy ma być ten alert i jaki ma pokazać tekst? Jak uważacie? Które sposoby są lepsze? Przy wielu takich wrzutach na model, kod java trochę były tym zawalony.
