For details, refer to the book below.

CHAPTER 1 What is Spring Framework?

Spring Framework overview and history

CHAPTER 2 Spring Core (DI x AOP) Explanation of core functions of Spring DI（Dependency Injection） Separate the generation of the instants that make up the component and the resolution of dependencies from the source code. Manage instances via DI container. ・ You can control the scope of the instance ・ You can control the life cycle of the instance ・ Common functions can be incorporated -Since the components are loosely coupled, unit testing becomes easier.

AOP（Aspect Oriented Programming） Aspect thinking programming to achieve "Separation Of Cross-Cutting Concerns".

AOP used in Spring project ・ Transaction management ・ Authorization processing ・ Cache processing ・ Asynchronous processing ・ Retry processing
