ConfigurableApplicationContext class abstract

A specialized ApplicationContext that allows for full configuration and lifecycle management.

ConfigurableApplicationContext extends the basic context interface with comprehensive lifecycle control and configuration capabilities, making it suitable for application bootstrap and runtime management.

Enhanced Capabilities:

• Lifecycle Management: Full control over context lifecycle phases
• Programmatic Configuration: Add initializers, listeners, and processors
• Dynamic Reconfiguration: Refresh context to reload configuration
• Resource Management: Proper cleanup and resource disposal
• Event System Integration: Complete event listener management

Typical Usage Pattern:

class MyApplicationContext extends AbstractApplicationContext 
    implements ConfigurableApplicationContext {
  
  @override
  Future<void> refresh() async {
    // Custom refresh logic
    await super.refresh();
  }
  
  @override
  Future<void> start() async {
    // Custom startup logic
    await super.start();
  }
}

void main() async {
  final context = MyApplicationContext();
  
  // Configure context before refresh
  context.addApplicationListener(MyEventListener());
  context.addPodFactoryPostProcessor(MyPostProcessor());
  
  // Initialize context
  await context.refresh();
  
  // Start context (if not auto-startup)
  await context.start();
  
  // Application runs...
  
  // Proper shutdown
  await context.stop();
  await context.close();
}

Lifecycle Phases:

1. Configuration: Add listeners, initializers, processors
2. Refresh: Load configuration, instantiate pods, publish events
3. Start: Transition to running state, start lifecycle beans
4. Running: Normal operation, event processing
5. Stop: Transition to stopped state, stop lifecycle beans
6. Close: Release resources, destroy pods, close context
