Advanced Spring — Lesson 1: Advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning

Learning Objectives

• Map the roles, prerequisites, data, dependencies, and expected outcome for advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning.
• Build a controlled advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning workflow and record evidence at each decision point.
• Evaluate the result against correctness, security, recovery, performance, and support criteria.

Detailed Topics

• Advanced Spring Boot configuration
• modular architecture
• REST API design
• validation
• error contracts
• versioning
• Ownership, prerequisites, data, and acceptance criteria for advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning
• Security, control, integration, performance, recovery, compliance, and support implications

Instructor Demonstration

Demonstrate advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning within a production-oriented Spring platform with secure REST APIs, data services, integration, resilience, and observable deployment behavior. Use representative data and capture API design and test suite so another practitioner can reproduce and verify the result.

Hands-On Exercise

Complete a controlled activity focused on advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning. Introduce a realistic case of API versioning breaks a consumer, isolate the cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Establish the current state, desired state, constraints, owners, and acceptable service impact.
• Compare implementation choices for advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning and their rollback consequences.
• Define acceptance evidence based on API design and test suite, then assign the next improvement owner.

Troubleshooting Guidance

When advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review API design and test suite before modifying configuration or data. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create a new control, security, performance, compliance, or integration defect.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by API design and test suite.
• Security, controls, data quality, integration, performance, recovery, compliance, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Advanced Spring Boot configuration, modular architecture, REST API design, validation, error contracts, versioning in a realistic Advanced Spring situation and defend the result with course-specific evidence.
