Answer from AI
The Spring container (ApplicationContext) is responsible for managing the lifecycle and configuration of objects (beans) in the application. It creates, configures, and links objects, providing dependency injection.
Role of the container:
- Managing creation of objects and their dependencies.
- Configuring components via annotations or XML.
- Ensuring inversion of control (IoC), which simplifies testing and maintenance.
For example, when declaring a class with the @Component annotation, Spring will automatically create its instance and inject necessary dependencies if they are declared with @Autowired.
