Implementation Logic

Repository Level

Service Level

Next, move to the service layer in the ProductService class to call the findByName() method from the repository.

Signature

You need to implement the logic to retrieve the product by its name from the repository and pass it to the controller layer.

Controller Level

Now, implement the findProductsByName() method in the ProductRestController to add a new endpoint for searching products by name.

Example request: localhost:8080/find?name=product1
