Merhaba Arkadaslar
Onceki bolumde basit Spring AOP orneklerini inceledik. Benzer ornekleri XML konfigurasyonu ile yapalim.
Advice Implementation siniflarimiz , LoggerWriter ve Validator siniflarimiz ayni sekilde olacak.
Konfigurasyon dosyamizda ProxyFactoryBean bean tanimlari olusturuyoruz target ve interceptorNames icin setter injection gerceklestiriyoruz.
