You can create a web controller for creating web applications in a simple way in such a folder src/main/kotlin/com/cubetiq/springboot/HelloController.kt:

package com.cubetiq.springboot

import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

@RestController
class HelloController {
    @GetMapping("/")
    fun index(): String {
        return "Greetings from Spring Boot!"
    }
}

After you have created a web controller and written the above code, you can run the project, and after a successful run, you need to open a browser and type in the following address: http://localhost:8080 and on this page you will see the Greetings from Spring Boot results! .
