Using different packages for Controllers when using in Spring Boot - spring-boot

Question

I am new in Spring boot.I trying to access the controller url but i didn't get any response from them.
We are followed spring boot project structure as per document.
I have used componentscan annotation and added scanBasePackageClasses in SpringBootApplication annotation.But still same.
HomeController :-
package com.main.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class HomeController {
#RequestMapping(value="/home",method=RequestMethod.GET)
public String home() {
System.out.println("home");
return "home";
}
}
GAppsApplication.java:-
package com.main;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import com.main.controllers.HomeController;
#ComponentScan({"com.main.controllers"})
#SpringBootApplication(scanBasePackageClasses={HomeController.class})
public class GAppsApplication {
public static void main(String[] args) {
SpringApplication.run(GAppsApplication.class, args);
}
}
For your reference i shared below logs

Answer 1

Change your controller to like below :
#RestController
#RequestMapping("/home")
public class HomeController {
#GetMapping
public String home() {
System.out.println("home");
return "home";
}
}
As your base package is com.main, so any package within com.main will automatically be scanned.
You don't need to put any special annotation to scan.
