/IOC 核心方法//防止 启动和销毁并发执行//启动步骤记录//刷新准备工作//创建 beanFactory 将配置文件解析为 beandefiniton 对象 注册到 beanFactory 中//ConfigurableListableBeanFactory是一个接口 真正干活的是 DefaultListableBeanFactory//beanFactory 预处理 主要是设置 beanFactory 类加载器及忽略一些自动装配 设置一些默认benatry {

上篇博客只是对 ApplicationContext 相关的接口做了一个简单的介绍Spring ApplicationContext 相关接口架构分析Spring 真的是一个非常优秀的框架，具有良好的结构设计和接口抽象，它的每一个接口职能单一，且都是具体功能到各个模块的高度抽象，且几乎每套接口都提供了一个默认的实现（defaultXXX），本文主要是以 Spring Framework 的 ApplicationContext 为中心，对其结构和功能的实现进行了简要的说明。#refresh()方法。
