Spring Boot: Developer

Course Description

Spring Boot: Developer prepares infrastructure and application professionals to work confidently with Spring and Spring Boot fundamentals, dependency injection, beans, auto-configuration, REST controllers, request mapping, validation. Activities emphasize repeatable configuration, realistic tests, evidence quality, and accountable handover.

Practical work also covers Spring Data, JPA, entities, repositories, Actuator, logging, metrics. Evidence such as Spring Boot project baseline and configuration-profile test, tested REST API and error-response contract, transactional data-access test and migration evidence, production-readiness checklist and application operations guide supports boundary testing, fault isolation, corrective action, and safe transition to operational ownership.

On completing the course, learners can defend the implementation and operation of a maintainable Spring Boot application with clean configuration, tested REST APIs, reliable data access, observable runtime behavior, secure deployment practices, and repeatable delivery. A final plan identifies acceptance gaps, rollback considerations, owners, and operational safeguards.

What You Will Learn

• Explain how Spring and Spring Boot fundamentals, dependency injection, and beans establish the technical foundation and influence later design decisions.
• Configure auto-configuration, starters, project structure, profiles, external configuration, and application lifecycle, then confirm readiness through Spring Boot project baseline and configuration-profile test instead of relying on completion messages alone.
• Execute a controlled workflow covering REST controllers, request mapping, and validation, preserving prerequisites, changes, and resulting service behavior.
• Read tested REST API and error-response contract to isolate invalid input returning an internal error instead of a stable client response, separate symptoms from causes, and choose a correction that can be safely retested.
• Integrate Spring Data, JPA, and entities with access, capacity, resilience, and downstream operational expectations.
• Challenge repositories, transactions, pagination, queries, database migrations, caching concepts, and test data management using normal and boundary cases, then defend the outcome with transactional data-access test and migration evidence.
• Investigate a health endpoint reporting success while a critical downstream dependency is unavailable by reviewing Actuator, logging, and metrics before applying a reversible fix.
• Prepare production-readiness checklist and application operations guide that demonstrates health checks, packaging, containers, configuration security, resilience, performance, CI/CD integration, and production troubleshooting and supports handover, monitoring, governance, and the next improvement decision.

SkillDynamo Training Approach

Sessions move from concept mapping to guided build, scenario analysis, evidence-based validation, reversible correction, operational review, and improvement planning. Both expected flows and failure conditions are tested before a result is accepted.
