Package org.springframework.context

@NonNullApi @NonNullFields package org.springframework.context

This package builds on the beans package to add support for message sources and for the Observer design pattern, and the ability for application objects to obtain resources using a consistent API.

There is no necessity for Spring applications to depend on ApplicationContext or even BeanFactory functionality explicitly. One of the strengths of the Spring architecture is that application objects can often be configured without any dependency on Spring-specific APIs.
