AnnotationConfigApplicationContext class

ApplicationContext implementation that supports annotation-based configuration.

This context extends GenericApplicationContext to add comprehensive support for annotation-driven dependency injection and component configuration in the Jetleaf framework.

Key Features:

• @Component Scanning: Automatically discovers and registers annotated classes
• @Configuration Support: Processes configuration classes with @Pod methods
• @Profile Activation: Conditionally registers components based on active profiles
• @Autowired Injection: Automatically wires dependencies between services
• Package Scanning: Scans specified packages for annotated components
• Annotation Processors: Built-in processors for common annotations
• Environment Integration: Profile-based conditional bean registration

Architecture:

The context combines programmatic registration with automatic classpath scanning to provide a flexible configuration system. It uses specialized processors to handle different annotation types and integrates with the Jetleaf environment system for profile-based activation.

Usage Example:

final context = AnnotationConfigApplicationContext();

// Register configuration classes
context.register(AppConfig);
context.register(DatabaseConfig);

// Scan packages for components
context.scan(['package:example/services', 'package:example/repositories']);

// Set active profiles
context.getEnvironment().setActiveProfiles(['production', 'database']);

// Initialize the context
await context.refresh();

// Retrieve components
final userService = await context.get<UserService>();

Annotation Support:

• @Component, @Service, @Repository - Component stereotypes
• @Configuration - Configuration classes with @Pod methods
• @Autowired - Dependency injection points
• @Qualifier - Dependency disambiguation
• @Profile - Conditional registration
• @EventListener - Event handling methods
