The divergence betwixt BeanFactory and ApplicationContext in Spring framework is only about other oft asked Spring interview question generally asked Java programmers amongst 2 to iv years sense inwards Java in addition to Spring. Both BeanFactory and ApplicationContext provides a agency to acquire a edible bean from Spring IOC container past times calling getBean("bean name"), but at that topographic point is only about divergence inwards at that topographic point working in addition to features provided past times them. One divergence betwixt edible bean manufacturing industrial plant life in addition to application context is that one-time solely instantiate edible bean when you lot telephone band getBean() method piece ApplicationContext instantiates Singleton edible bean when the container is started, It doesn't hold back for getBean to locomote called. This interview questions is 3rd on my listing of oft asked bound questions e.g. Setter vs Constructor Injection and What is default compass of Spring bean. If you lot are preparing for Java interview in addition to expecting only about Spring framework question, It’s worth preparing those questions.
If you lot are novel inwards Spring framework in addition to exploring Spring API in addition to classes than you lot would similar cheque my post service on only about Spring utility functions e.g. calculating fourth dimension divergence amongst StopWatch and escaping XML particular characters using Spring HtmlUtils. Coming dorsum to BeanFactory vs ApplicationContext, let’s meet only about to a greater extent than divergence betwixt them inwards side past times side section.

BeanFactory vs ApplicationContext inwards Spring
Before seeing divergence betwixt ApplicationContext in addition to BeanFactory, allow meet only about similarity betwixt both of them. Spring provides 2 kinds of IOC container, 1 is BeanFactory and other is ApplicationContext. Syntactically BeanFactory and ApplicationContext both are Java interfaces in addition to ApplicationContext extends BeanFactory. Both of them are configuration using XML configuration file. In brusk BeanFactory provides basic IOC in addition to DI features piece ApplicationContext provides advanced features. Apart from these, Here are few to a greater extent than divergence betwixt BeanFactory and ApplicationContext which is mostly based upon features supported past times them.
1) BeanFactory doesn't render back upwards for internationalization i.e. i18n but ApplicationContext provides back upwards for it.
2) Another divergence betwixt BeanFactory vs ApplicationContext is might to unwrap effect to beans that are registered every bit listener.
3) One of the pop implementation of BeanFactory interface is XMLBeanFactory while 1 of the pop implementation of ApplicationContext interface is ClassPathXmlApplicationContext. On Java spider web application nosotros utilization WebApplicationContext which extends ApplicationContext interface in addition to adds getServletContext method.
4) If you lot are using motorcar wiring in addition to using BeanFactory than you lot demand to register AutoWiredBeanPostProcessor using API which you lot tin laissez passer on notice configure inwards XML if you lot are using ApplicationContext. In summary BeanFactory is OK for testing in addition to non production utilization but ApplicationContext is to a greater extent than characteristic rich container implementation in addition to should locomote favored over BeanFactory
Eclipse by using next snippet of code :
public static void main(String args[]){
ApplicationContext ctx =new ClassPathXmlApplicationContext("beans.xml");
Hello hullo =(Hello) ctx.getBean("hello");
hello.sayHello("John");
}
ApplicationContext ctx =new ClassPathXmlApplicationContext("beans.xml");
Hello hullo =(Hello) ctx.getBean("hello");
hello.sayHello("John");
}
here beans.xml is your bound configuration file in addition to “hello” is a edible bean defined inwards that bound configuration file. Here nosotros convey used ClassPathXmlApplicationContext which is an implementation of ApplicationContext interface inwards Spring.
