/** * 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. * * <p>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. */ package org.springframework.context;
