Spring Boot Controller for Data Display and Main Page

This code snippet showcases a controller class within a Spring Boot application. It features two methods annotated with '@GetMapping', which map incoming HTTP GET requests to specific URLs.

1. The 'dataDisplay()' method handles the '/dataDisplay' URL and returns the string 'dataDisplay'. This string typically represents the name of an HTML template or view to be rendered for displaying specific data.

2. The 'showMainPage()' method maps to the '/main' URL and returns the string 'main'. This string signifies the main page or view of the application, likely a landing page or a central hub for navigation.

It's important to note that the returned strings 'dataDisplay' and 'main' represent the filenames of HTML templates or views located in the 'src/main/resources/templates' directory within the Spring Boot project. These templates are responsible for defining the actual HTML content that will be presented to the user.
