spring管理bean源码解析

1. 从启动类开始

1. public static void main(String[] args) {
2.         // Run the SpringApplication class with the Application class as the first argument
3.         SpringApplication.run(Application.class, args);
4.     }

2. bean 实例化

1. // SpringAplication row=1294
2. run()
3. // SpringAplication row=1035
4. run()
5. // SpringAplication row=308
6. refreshContext(context);
7. //  SpringAplication row=407
8. refresh(context);
9. //  SpringAplication row=734
10. applicationContext.refresh();
12. // AbstractApplicationContext row=583
13. finishBeanFactoryInitialization(beanFactory);
14. // AbstractApplicationContext row=918
15. beanFactory.preInstantiateSingletons();
17. // DefaultListableBeanFactory row=922
18. preInstantiateSingletons();
20. // AbstractBeanFactory row=207
21. getBean();
22. // AbstractBeanFactory row=248
23. goGetBean()
24. // AbstractAutowareCapableBeanFactory row=503
25. createBean()

3. bean 依赖注入

1. // SpringAplication row=1294
2. run()
3. // SpringAplication row=1035
4. run()
5. // SpringAplication row=308
6. refreshContext(context);
7. //  SpringAplication row=407
8. refresh(context);
9. //  SpringAplication row=734
10. applicationContext.refresh();
12. // AbstractApplicationContext row=583
13. finishBeanFactoryInitialization(beanFactory);

4. 删除实例及其依赖实例

1. // DefaultSingletonBeanRegistry row=550
2. destroySingleton()
3. // DefaultSingletonBeanRegistry row=568
4. destroyBean()
5. // AbstractFactoryBean row=197
6. destroy()
