Build Tools & Deployment
- Maven: pom.xml — dependency management, build lifecycle (compile, test, package, install, deploy). Most popular Java build tool. Convention over configuration
- Gradle: build.gradle with Groovy/Kotlin DSL — faster than Maven (incremental builds, build cache). Growing adoption. Better for multi-module projects and custom tasks
- Docker: Multi-stage Dockerfile — FROM maven AS build (compile) → FROM eclipse-temurin:21-jre (runtime). Small production images (~200MB). Spring Boot has built-in Buildpacks support
- CI/CD: GitHub Actions / Jenkins — mvn test on every PR, mvn package + docker build on merge to main, deploy to Kubernetes. Automated quality gates
- Logging: SLF4J + Logback — structured logging with MDC (Mapped Diagnostic Context) for request tracing. Use log.info('Order {} created for user {}', orderId, userId) — parameterized, not concatenated
- Monitoring: Spring Boot Actuator + Micrometer + Prometheus + Grafana — application metrics (request rates, latency, JVM memory, GC pauses) with dashboards and alerting
