Project Implementation Summary

✅ Completed Tasks

1. Swagger/OpenAPI Implementation ✅

• SpringDoc OpenAPI 2.7.0 integrated
• OpenAPI configuration class created with custom metadata
• All controller endpoints annotated with OpenAPI documentation
• DTOs annotated with schema descriptions and examples
• Interactive Swagger UI accessible at /swagger-ui.html
• OpenAPI JSON spec available at /v3/api-docs

2. Error Analysis & Resolution ✅

• Identified Eclipse IDE errors as Lombok annotation processing issues
• Confirmed all code compiles successfully with Maven
• All tests pass (1 test, 0 failures, 0 errors)
• Application runs without runtime errors
• Created Eclipse setup guide for Lombok plugin installation

4. Dependencies Fixed ✅

Removed conflicting dependencies:

• spring-boot-starter-data-rest (caused HATEOAS conflicts)
• spring-boot-starter-data-rest-test
• spring-boot-starter-data-jpa-test
• spring-boot-starter-webmvc-test

Added dependencies:

• springdoc-openapi-starter-webmvc-ui (2.7.0)
• spring-boot-starter-validation
• spring-boot-starter-test (replacement for removed test deps)

5. Configuration Files

• application.properties - Added SpringDoc configuration
• pom.xml - Fixed dependencies, added SpringDoc
• Dockerfile - Ready for containerization
• .dockerignore - Optimized Docker builds

6. Documentation ✅

• README.md - Updated with Swagger info and Eclipse setup
• TESTING.md - NEW - Complete test results and validation
• SWAGGER.md - NEW - Swagger/OpenAPI quick reference guide

🧪 Test Results

Compilation

./mvnw clean compile

✅ BUILD SUCCESS

Testing

./mvnw verify

✅ Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

Runtime Testing

✅ All CRUD operations working ✅ Async operations functional ✅ Validation working (400 Bad Request) ✅ Duplicate email detection (409 Conflict) ✅ 404 handling for missing customers ✅ H2 database accessible ✅ Swagger UI fully functional

📊 API Endpoints with Swagger

Method	Endpoint	Status	Swagger Doc
GET	/api/customers	✅	✅ Documented
GET	/api/customers/{id}	✅	✅ Documented
POST	/api/customers	✅	✅ Documented
PUT	/api/customers/{id}	✅	✅ Documented
DELETE	/api/customers/{id}	✅	✅ Documented

🐳 Docker

Build

docker build -t apirestful:latest .

Run

docker run -p 8080:8080 apirestful:latest

🔧 Eclipse IDE Errors Explanation

What You See in Eclipse:

• Red error markers on Lombok annotations
• "Cannot resolve method" errors for getters/setters
• "log cannot be resolved" errors
• "@Builder" and "@RequiredArgsConstructor" issues

Why:

Eclipse annotation processing not configured for Lombok

Impact:

NONE - Code compiles and runs perfectly with Maven

Solution:

1. Install Lombok plugin: java -jar lombok.jar
2. Select Eclipse installation
3. Restart Eclipse
4. Errors will disappear

Evidence It's Only IDE Issue:

./mvnw clean verify
[INFO] BUILD SUCCESS
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

Application runs successfully:

2025-12-13T21:47:32.275+01:00  INFO 15437 --- [apirestful] [           main] 
c.m.apirestful.ApirestfulApplication     : Started ApirestfulApplication in 3.939 seconds

🎯 Key Features

1. Async Processing - All operations use @Async with CompletableFuture
2. Swagger/OpenAPI 3.0 - Complete interactive API documentation
3. Validation - Jakarta Validation with custom error messages
4. Exception Handling - Global handler with proper HTTP status codes
5. H2 Database - In-memory for easy testing
6. Security - Configured for development (can be enhanced)
7. Docker Ready - Multi-stage build optimized
8. Lombok - Reduced boilerplate code

📝 Quick Start

# Clone and navigate to project
cd /home/ale/eclipse-workspace3/apirestful

# Run the application
./mvnw spring-boot:run

# Access Swagger UI
open http://localhost:8080/swagger-ui.html

# Access H2 Console
open http://localhost:8080/h2-console

🎓 What Was Fixed

1. ❌ Spring Data REST dependency conflict → ✅ Removed
2. ❌ HATEOAS version incompatibility → ✅ Resolved by removing data-rest
3. ❌ Missing SpringDoc dependency → ✅ Added version 2.7.0
4. ❌ Security blocking Swagger → ✅ Updated to permit Swagger endpoints
5. ❌ No OpenAPI annotations → ✅ Added comprehensive annotations
6. ❌ Eclipse Lombok errors → ✅ Explained (IDE only, not code issue)

✨ Final Status

Project Status: ✅ FULLY FUNCTIONAL

Build: ✅ SUCCESS
Tests: ✅ PASSING
Runtime: ✅ WORKING
Swagger: ✅ INTEGRATED
Docker: ✅ READY
