spring boot 启动监听获取ApplicationContext上下文

如果需要获取ApringApplication上下文，可以实现ApplicationContextAware接口，重写setApplicationContext方法；

@Component
public class ApplicationAware implements ApplicationContextAware {private static ApplicationContext __applicationContext;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {System.out.println(".....ApplicationAware");__applicationContext = applicationContext;}
}

以上取到的ApplicationContext就是当前运行的ApplicationContext上下文！
