Product Microservices in Spring Boot 3.3.0 / Gradle 8.8

Featuring microservices architecture, the walk aims to build an end-to-end Product Service supported by modern stacks: Spring Boot, Gradle, Docker, Kubernetes, monitoring and logging tools which I'll list below. This repo contains codebase for the Product Service comprising:

• api the library that defines interfaces and plain old Java objects that the Product Service implements in the concrete services
• util this library defines protocol information such as Services Addresses and error handling classes
• product-service this is the core microservice features the Product itself
• recommendation-service entails recommendations related to the Product
• review-service serves reviews given by authors related to the Product
• product-composite-service aggregates the three microservices above such that they sit behind this service. The composite makes the actual communication to the microservices and delivers an aggregate response to the requesting client

• Updated ServiceUtil to give the correct hostname instead of IP address of microservice instance
• Created Dockerfile for each microservice that will build image in layers that are cacheable. Here, we explode uber jar and organize the running of the jar file org.springframework.boot.loader.launch.JarLauncher
• Created Docker Compose yml script to start and tear down the microservice landscape
• Updated the test script to start the landscape for testing and tear down the landscape after tests ./test-em-all.bash start stop

• Added API Documentation

• Build and start the landscape:

./gradlew build && docker compose build && docker compose up -d

The api doc will be accessible via http://localhost:8080/openapi/swagger-ui.html

This documentation is continued in the README file of the Microservices-Diary documentation project.
