Dependency Injection<\/a> yakla\u015f\u0131m\u0131 ile Factory Method Design Pattern<\/a> aras\u0131nda bir b\u00fct\u00fcnl\u00fck sa\u011flayarak bir proje \u00fczerinde beraber nas\u0131l bir tasar\u0131m ger\u00e7ekle\u015ftirebiliriz? sorusuna cevap vermeye \u00e7al\u0131\u015faca\u011f\u0131z.<\/p>\n

Bu iki konu \u00fczerinde detayl\u0131 durmayaca\u011f\u0131m. Lakin k\u0131saca \u00f6zetleyecek olursak e\u011fer Dependency Injection, projedeki ba\u011f\u0131ml\u0131l\u0131k entegrasyonlar\u0131n\u0131 soyutlamak \u00fczerine profesyonel maksatl\u0131 bir yakla\u015f\u0131m sergilememizi sa\u011flarken, Factory Method Design Pattern ise birbirleriyle ili\u015fkisel nesneleri \u00fcretirken alternatif bir yol sunmaktayd\u0131.<\/p>\n

\u015euanda bu i\u00e7erikte yapmak istedi\u011fimiz olay ise bu iki yakla\u015f\u0131m\u0131 uygulayabilece\u011fimiz \u00f6rnek bir proje ger\u00e7ekle\u015ftirmektir.<\/p>\n

\u00d6rnek projeyi makalenin sonunda indirebilirsiniz. Senaryo \u00e7ok basit oldu\u011fu i\u00e7in bir film projesinde \u00f6rneklendirme ama\u00e7l\u0131 \u00e7al\u0131\u015faca\u011f\u0131m\u0131z\u0131 s\u00f6ylemenin yeterli oldu\u011funu d\u00fc\u015f\u00fcn\u00fcyorum…<\/p>\n
