The departure betwixt BeanFactory and ApplicationContext in Spring framework is approximately other ofttimes asked Spring interview question to a greater extent than often than non asked Java programmers alongside 2 to four years sense inwards Java together with Spring. Both BeanFactory and ApplicationContext provides a agency to acquire a edible bean from Spring IOC container past times calling getBean("bean name"), precisely in that place is approximately departure inwards in that place working together with features provided past times them. One departure betwixt edible bean manufactory together with application context is that erstwhile exclusively instantiate edible bean when you lot telephone phone getBean() method acre ApplicationContext instantiates Singleton edible bean when the container is started, It doesn't hold off for getBean to move called. This interview questions is tertiary on my listing of ofttimes asked leap questions e.g. Setter vs Constructor Injection and What is default ambit of Spring bean. If you lot are preparing for Java interview together with expecting approximately Spring framework question, It’s worth preparing those questions.
If you lot are novel inwards Spring framework together with exploring Spring API together with classes than you lot would similar banking corporation jibe my post on approximately Spring utility functions e.g. calculating fourth dimension departure alongside StopWatch and escaping XML particular characters using Spring HtmlUtils. Coming dorsum to BeanFactory vs ApplicationContext, let’s come across approximately to a greater extent than departure betwixt them inwards adjacent section.

BeanFactory vs ApplicationContext inwards Spring
Before seeing departure betwixt ApplicationContext together with BeanFactory, allow come across approximately similarity betwixt both of them. Spring provides ii kinds of IOC container, i is BeanFactory and other is ApplicationContext. Syntactically BeanFactory and ApplicationContext both are Java interfaces together with ApplicationContext extends BeanFactory. Both of them are configuration using XML configuration file. In brusk BeanFactory provides basic IOC together with DI features acre ApplicationContext provides advanced features. Apart from these, Here are few to a greater extent than departure betwixt BeanFactory and ApplicationContext which is mostly based upon features supported past times them.
1) BeanFactory doesn't supply back upwardly for internationalization i.e. i18n precisely ApplicationContext provides back upwardly for it.
2) Another departure betwixt BeanFactory vs ApplicationContext is might to pose out outcome to beans that are registered equally listener.
3) One of the pop implementation of BeanFactory interface is XMLBeanFactory while i of the pop implementation of ApplicationContext interface is ClassPathXmlApplicationContext. On Java spider web application nosotros utilization WebApplicationContext which extends ApplicationContext interface together with adds getServletContext method.
4) If you lot are using motorcar wiring together with using BeanFactory than you lot demand to register AutoWiredBeanPostProcessor using API which you lot tin configure inwards XML if you lot are using ApplicationContext. In summary BeanFactory is OK for testing together with non production utilization precisely ApplicationContext is to a greater extent than characteristic rich container implementation together with should move favored over BeanFactory
Eclipse by using next snippet of code :
public static void main(String args[]){
ApplicationContext ctx =new ClassPathXmlApplicationContext("beans.xml");
Hello hi =(Hello) ctx.getBean("hello");
hello.sayHello("John");
}
ApplicationContext ctx =new ClassPathXmlApplicationContext("beans.xml");
Hello hi =(Hello) ctx.getBean("hello");
hello.sayHello("John");
}
here beans.xml is your leap configuration file together with “hello” is a edible bean defined inwards that leap configuration file. Here nosotros accept used ClassPathXmlApplicationContext which is an implementation of ApplicationContext interface inwards Spring.
