[Spring Overview] Principle level: Spring interview family bucket

For Spring interviews, there are not many interview questions that can be used to form interview questions.
Under this category, there are a total of 25 articles, except for the general description, there are 24

001 Spring boot initialization involves patterns

002 IOC (the second blog of IOC foundation) (ApplicationContext two interfaces)
Four AOPs (1, what is AOP; 2, AOP five annotations; 3. Static AOP and dynamic AOP; 4. AOP invalidation) and annotations

003 Spring life cycle and extension points (together with the two): life cycle + seven extension points
1, Spring extension point BeanFactoryPostProcessor interface and BeanDifinitionRegistryPostProcessor interface
2, Spring extension point BeanPostProcessor interface
3, Spring @Import
4, Spring extension point Aware interface family
5, Spring extension point
SmartLifeCycle interface 6, Spring extension point FactoryBean interface
7, Spring event monitoring mechanism
environment, internationalization, event broadcast and reception, unified resource loading (ApplicationContext four interfaces, degree of importance : Events, unified resource loading> Environment> Internationalization, the first three can form interview test sites, while internationalization cannot form interview test sites)
Spring handles circular dependencies (one of the three, interview focus)

004 Global exception handling, environment env
