Checklist for New Java Application or Service

This article outlines the essential steps and considerations for Creating a new Java Application or Service

• Spring Initializr is great tool for creating initial projects with predefined initial setup. I find it really helpful.
• Set up Sonar project for the repository. If it is open source project, Sonar Cloud is really helpful for maintaining good quality code
• Setup Continues Integration(CI) workflow for each commit and merge request. Feel free to have look: Journey API | ci-build-workflow.yml
• Setup Continues Deployment(CD) workflow for automated deployment to QA & LIVE environments. Feel free to have look: Journey API | release-workflow.yml
• Docker Compose really helps and boost developer productivity and reduce complexity for environment setup.
• Containerization: Use Docker or other container solutions to package the application consistently. Feel free to have look Journey API | Dockerfile
• Renovate Bot integration really helps to automatically update dependencies. Feel free to have look Journey API | renovate.json
• OpenRewrite integration really powerful tool to maintain good code quality and automated refactoring to reduce technical debt. Feel free to have look Journey API | rewrite.yml
• Open API with Swagger Document the code and create developer-friendly API documentation. Personally I would recommend Open API Specification with Swagger UI. Feel free to have look Journey API Configuration & REST API Documentation
