\"\"Finalmente vedremo come realizzare le pagine JSP, ma prima, come al solito, bisogna mettere mano ai file di configurazione. Negli scorsi articoli infatti siamo partiti da una situazione molto generica, per poi suddividere l’applicazione in strati; questo ci obbliga ad effettuare periodicamente dei refactoring<\/em> dei sorgenti; con la versione 3.x di Spring comunque si \u00e8 cercato di semplificare molto le configurazioni, quindi si tratter\u00e0 di cambiamenti molto isolati.<\/p>\n

Per completezza riportiamo tutti i file di configurazione attuali, con le modifiche gi\u00e0 applicate; il primo \u00e8 src\/main\/resources\/applicationContext.xml<\/em>:<\/p>\n
