Springboot Patterns

A solid reference for the controller-service-repository pattern and common Spring Boot plumbing. You get working examples of pagination, validation with Bean Validation annotations, global exception handlers, caching with @Cacheable, async methods, and request logging filters. The code leans heavily on constructor injection and records for DTOs, which is clean. One thing worth noting: the rate limiting example includes a detailed security note about X-Forwarded-For headers and reverse proxies, which is the kind of production detail that actually matters. Use this when you're setting up a new Spring Boot API or need to remember how Spring Data JPA queries or @ControllerAdvice work without digging through documentation.

Spring Boot Development Patterns

Spring Boot architecture and API patterns for scalable, production-grade services.

When to Activate

Building REST APIs with Spring MVC or WebFlux
Structuring controller → service → repository layers
Configuring Spring Data JPA, caching, or async processing
Adding validation, exception handling, or pagination
Setting up profiles for dev/staging/production environments
Implementing event-driven patterns with Spring Events or Kafka

REST API Structure

@RestController
@RequestMapping("/api/markets")
@Validated
class MarketController {
  private final MarketService marketService;

  MarketController(MarketService marketService) {
    this.marketService = marketService;
  }

  @GetMapping
  ResponseEntity<Page<MarketResponse>> list(
      @RequestParam(defaultValue = "0") int page,
      @RequestParam(defaultValue = "20") int size) {
    Page<Market> markets = marketService.list(PageRequest.of(page, size));
    return ResponseEntity.ok(markets.map(MarketResponse::from));
  }
