Spring Boot Enterprise Development with Microservices MongoDB and RabbitMQ — Lesson 1: Spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure

Learning Objectives

• Map the roles, prerequisites, data, dependencies, and expected outcome for spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure.
• Build a controlled spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure workflow and record evidence at each decision point.
• Evaluate the result against correctness, security, recovery, performance, and support criteria.

Detailed Topics

• Spring Boot enterprise architecture
• microservice boundaries
• configuration
• dependency injection
• REST contracts
• project structure
• Ownership, prerequisites, data, and acceptance criteria for spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure
• Security, control, integration, performance, recovery, compliance, and support implications

Instructor Demonstration

Demonstrate spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure within a Spring Boot microservices solution using MongoDB and RabbitMQ, engineered for resilient messaging, secure APIs, observability, and controlled deployment. Use representative data and capture service architecture and API contract so another practitioner can reproduce and verify the result.

Hands-On Exercise

Complete a controlled activity focused on spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure. Introduce a realistic case of service contract incompatibility, 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 spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure and their rollback consequences.
• Define acceptance evidence based on service architecture and API contract, then assign the next improvement owner.

Troubleshooting Guidance

When spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review service architecture and API contract 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 service architecture and API contract.
• 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 Spring Boot enterprise architecture, microservice boundaries, configuration, dependency injection, REST contracts, project structure in a realistic Spring Boot Enterprise Development with Microservices MongoDB and RabbitMQ situation and defend the result with course-specific evidence.
