In Spring MVC, HTTP requests are handled by controllers. Controllers are classes that have been annotated with @Controller—similar to how we annotate rest controllers with @RestController. The best way to understand the way controllers work is to have an example to scrutinize. Let us create a simple Spring MVC controller that handles HTTP GET requests sent to the /say/hello path by returning a view, which has the responsibility of rendering an HTML page to a user.
Create a controller package in com.example.placereviewer and add the following class to it:
package com.example.placereviewer.controllerimport org.springframework.stereotype.Controllerimport org.springframework.web.bind.annotation.GetMapping
