Spring1 ()

Objective:

Reduce the complexity of Java development

Usage Policy:
Lightweight and minimal intrusive programming based on Pojo

Loose coupling via Dependency injection and interface-oriented

Declarative programming based on facets and conventions

Reduce style code with facets and templates

Dependency Injection: The object variables defined by spring that manage the dependencies of the objects in the system do not need to create or manage their own dependencies, but the spring container helps us create the specified instance and injects the instance into the object variable that needs to depend on the object

Assembly: The behavior of creating collaborative relationships between application components is called assembly, one step. There are many ways to implement

Automated assembly: Through component scanning and automated assembly

Component Scan: Spring Auto-discovery Bean created by app context

Automatic assembly: Spring automatically satisfies bean dependencies and injects beans
