Spring源码学习笔记(十三)、finishRefresh

一、方法功能概述

// 最后一步,完成刷新
finishRefresh();

最后一步,完成刷新

• 清理缓存资源

• 初始化lifecycleProcessor,默认是DefaultLifecycleProcessor

• 触发DefaultLifecycleProcessor的onRefresh方法

• 发布事件ContextRefreshedEvent

• 注册ApplicationContext到LiveBeansView内部的applicationContexts中

二、整体代码展示

//AbstractApplicationContext
/**
 * Finish the refresh of this context, invoking the LifecycleProcessor's
 * onRefresh() method and publishing the
 * {@link org.springframework.context.event.ContextRefreshedEvent}.
 * 完成此上下文的刷新，调用LifecycleProcessor的onRefresh方法并发布事件ContextRefreshedEvent
 */
protected void finishRefresh() {
    // 清理缓存资源
    clearResourceCaches();

    // 初始化lifecycleProcessor,默认是DefaultLifecycleProcessor
    initLifecycleProcessor();

    // 触发DefaultLifecycleProcessor的onRefresh方法
    getLifecycleProcessor().onRefresh();

    // 发布事件ContextRefreshedEvent
    publishEvent(new ContextRefreshedEvent(this));

    // 注册ApplicationContext到LiveBeansView内部的applicationContexts中
    LiveBeansView.registerApplicationContext(this);
}
