Features

• Dependency Injection Frameworks - Implements a full dependency injection framework that automatically manages object creation and resolves component dependencies.
• Dependency Injection - Implements a core dependency injection system to decouple software components through automated wiring.
• Java Component Containers - Functions as a Java component container that handles the creation and management of singleton and prototype scoped objects.
• Classpath Component Scanners - Provides automatic discovery and registration of managed beans by scanning the classpath for annotations.
• Annotation-Based Component Scanning - Automatically detects and registers classes as managed beans by scanning packages for annotations.
• Aspect-Oriented Programming - Implements techniques for modularizing cross-cutting concerns by intercepting method calls.
• Aspect-Oriented Programming Frameworks - Implements a system for modularizing cross-cutting concerns using dynamic proxies and interceptors.
• Object Lifecycle Management - Controls the creation, registration, and destruction of objects to decouple instantiation from usage.
• Inversion-of-Control Containers - Provides an inversion-of-control container that manages bean lifecycles and resolves dependencies through automated instantiation.
• Singleton Instance Sharing - Manages a central map of singleton instances to ensure shared object access across the dependency graph.
• Dependency Injection Population - Uses Java reflection and metadata to automatically populate object properties with their required dependencies.
• Method Interception Proxies - Uses dynamic proxies to intercept method calls, allowing the injection of custom behavior.
• Spring Bean Contexts - Coordinates resource loading and object recognition within a managed bean application context.
• External Configuration Loading - Provides mechanisms to load external configuration files for component discovery and registration.
• Hook Registration - Implements a registration mechanism for executing custom logic during object initialization and destruction.
• Framework Architecture Studies - Provides a simplified implementation of the Spring framework as a resource for studying IoC and DI internals.
• Framework Implementation Studies - Provides a simplified implementation of the Spring framework specifically designed for studying the internals of IoC and DI containers.
• Bean Scope Definitions - Defines how objects are instantiated and shared using scope definitions and factory patterns.
• Initialization and Shutdown Hooks - Provides initialization and shutdown hooks to trigger specific methods during the application lifecycle.
• Event Triggering - Implements mechanisms for programmatically firing events to notify registered listeners within the container.
• Container Event Observers - Implements an observer-pattern event dispatcher to notify listeners of internal system events.
• XML Configurations - Supports the use of external XML files to define object relationships and application settings.
• Java Frameworks - A simplified implementation of the Spring framework for learning.
