Springboot Patterns

This covers the bread and butter patterns you'll use building Spring Boot APIs: proper controller-service-repository layering, JPA repositories with custom queries, request/response DTOs with validation, global exception handling, and caching with eviction. It includes practical async processing, structured logging with correlation IDs, and pagination patterns. The rate limiting example is thorough about the security implications of using forwarded headers behind proxies. Good for mid-level developers who know Spring basics but want to see how the pieces fit together in production code, especially around error handling and non-functional requirements like caching and monitoring.

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));
  }
