Spring-ApplicationContext refresh的流程

refresh的12个步骤
        1.prepareRefresh //完成整体的准备工作
        2.obtainFreshBeanFactory //2-6完成beanfactory的准备工作
        3.prepareBeanFactory
        4.postProcessBeanFactory
        5.invokeBeanFactoryPostProcessors
        6.registerBeanPostProcessors
        7.initMessageSource //7-12ApplicationContext 独有的一些功能的准备
        8.initApplicationEventMulticaster
        9.onRefresh
        10.registerListeners
        11.finishBeanFactoryInitialization //创建单例对象 在这里
        12.finishRefresh

Spring ApplicationContext refresh的流程_KNCCB的博客-CSDN博客ApplicationContext refresh的流程12个步骤：1.prepareRefresh1.这一步创建和准备了Environment对象初始化键值信息。作用之一是为后续@Value，值注入提供。2.obtainFreshBeanFactory1.BeanFactory的作用是负责bean的创建、依赖注入和初始化。2.BeanDefinition作为bean的设计蓝图，规定了bean的特征。BeanDefinition中的bean信息可以从xml、配置类或扫描获取。3.prehttps://blog.csdn.net/weixin_42338191/article/details/124729113?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522165640673516782390558214%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fall.%2522%257D&request_id=165640673516782390558214&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~all~first_rank_ecpm_v1~pc_rank_34-6-124729113-null-null.142^v24^pc_rank_34,157^v15^new_3&utm_term=ApplicationContext+refresh&spm=1018.2226.3001.4187
