Spring Boot in Enterprise: Patterns for Large-Scale Applications

Spring Boot simplifies development, but enterprise scale requires additional patterns.

Configuration Management

Externalize all configuration. Use Spring Cloud Config or Kubernetes ConfigMaps. Never hardcode environment-specific values.

Security Integration

Spring Security integrates with enterprise identity providers. OAuth2/OIDC for user authentication, JWT for service-to-service communication.

Testing Strategy

• Unit tests with mocked dependencies
• Integration tests with Testcontainers
• Contract tests for API consumers
• Performance tests with realistic data

Production Readiness

• Actuator endpoints for health and metrics
• Structured logging (JSON format)
• Graceful shutdown handling
• Connection pool monitoring
