Creating New Products with Validation in Spring Boot: Form Setup & Database Save
In this video, we’ll dive into adding new products to our Spring Boot application. Starting with a product creation form, you’ll learn how to add fields for each product attribute, complete with validation error handling to guide user input. We’ll implement real-time validation using error classes to highlight missing or incorrect entries, ensuring data integrity before submission.
Next, we set up a POST route in the controller to handle form submissions. Using @ModelAttribute and @Valid with a ProductDto, we validate inputs, display errors when needed, and convert valid data to a Product entity for saving in the database. Once saved, the app redirects to the updated product list, completing the creation workflow. This video equips you to build a fully functional product creation form with robust validation and database integration in Spring Boot!
