Wants to create a Simple E-commerce App with Java in 60 Minutes?

Want to build a simple e-commerce app in just 60 minutes? Here’s how.
Start by generating a Spring Boot project with Spring Initializr — add Web, JPA, and H2 dependencies.
Next, create models for Product, User, and Order.
Set up your repository interfaces — Spring Data JPA does most of the work for you.
Create controllers for product listing, user checkout, and order handling.
Add basic endpoints: /products, /cart, /checkout.
For the frontend, use Thymeleaf or even plain HTML to keep it fast.
Use in-memory H2 for quick testing — no DB setup needed.
By the end, you’ll have a working backend that mimics real e-commerce logic.
Keep it simple, focus on flow — and you can build big later.
