Spring – The Context: ApplicationContext vs. BeanFactory

This article describes the difference between ApplicationContext and BeanFactory in Spring framework.

- BeanFactory is recommended for lightweight framework like — Mobile and Applet.

- BeanFactory is core component of Spring IoC container.

- As ApplicationContext extends BeanFactory so ApplicationContext is more powerful than BeanFactory (like AOP, Internationalization etc.)

-          You can configure your beans in the Spring IoC container through XML files, properties files, annotations, or even APIs.

-          Container reads these beans by using BeanFactory (or ApplicationContext)

-          Let’s say you define the beans in XML file, say applicationcontext.xml.

-          Now BeanFactory has to read applicationcontext.xml to load the beans in container.

-          For this BeanFactory needs an interface that can provide the xml file o BeanFactory.

-          This interface called resource object.

-          Sample:

-          In case of ApplicationContext, the resource object is implemented internally, so as use We don’t  need of resource object.
