Java Spring Boot

Course Description

Java Spring Boot develops practical capability in developing production-ready Java applications with Spring Boot using dependency injection, web APIs, persistence, security, testing, observability, configuration, and deployment. The learning path is organized around a secure order-management REST service built with Spring Boot, persisted transactionally, tested across layers, observed in production, and packaged for container deployment.

Learners progress from architecture, process, or business understanding into configuration, development, analysis, validation, troubleshooting, and operational handoff. Every lesson uses the controls, tools, data structures, risks, failure modes, and decisions relevant to this exact Oracle pathway.

The content is independently written for SkillDynamo using the supplied source page for title, update date, and topic alignment. Learners finish with reproducible evidence, a course-specific implementation record or runbook, and a prioritized improvement action.

What You Will Learn

• Explain and apply Spring Boot starters, auto-configuration, application bootstrap, and project structure within Java Spring Boot.
• Configure, validate, or troubleshoot beans, dependency injection, configuration classes, component scanning, and lifecycle, properties, YAML, profiles, external configuration, validation, and secrets, and layered architecture, domain boundaries, logging, and development workflow using course-specific evidence.
• Explain and apply Spring MVC controllers, request mapping, DTOs, serialization, and content negotiation within Java Spring Boot.
• Configure, validate, or troubleshoot Bean Validation, custom validators, request constraints, and error responses, exception handlers, status codes, problem details, and correlation IDs, and OpenAPI documentation, pagination, versioning, testing, and API compatibility using course-specific evidence.
• Explain and apply entities, relationships, repositories, queries, projections, and specifications within Java Spring Boot.
• Configure, validate, or troubleshoot transactions, isolation, propagation, locking, and consistency, Flyway or Liquibase migrations, seed data, rollback, and environments, and N+1 issues, fetch plans, indexing, connection pools, and query evidence using course-specific evidence.
• Explain and apply Spring Security filter chain, authentication, authorization, JWT, and method security within Java Spring Boot.
• Configure, validate, or troubleshoot unit, slice, integration, repository, controller, and Testcontainers testing, Actuator health, metrics, tracing, logging, and alert readiness, and resilience patterns, Docker images, configuration, deployment, rollback, and runbook using course-specific evidence.

SkillDynamo Training Approach

The training follows a secure order-management REST service built with Spring Boot, persisted transactionally, tested across layers, observed in production, and packaged for container deployment. Activities combine product-specific demonstrations, guided implementation, hands-on exercises, scenario analysis, validation checklists, structured troubleshooting, solution review, and a final improvement plan. Learners document assumptions, settings, commands or transactions, outputs, exceptions, corrective actions, security and governance trade-offs, rollback needs, and operational ownership.
