Spring boot not scanning any sub packages and also the class files under same package

After i write a simple route using rest controller and spring boot the routes always return 404 whether If the route is mention in a separate package or in same package. The route only works if the route is defined in the main function where @SpringBootApplication is mentioned please help me package com.gowtham;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


@SpringBootApplication
@ComponentScan(basePackages = "com.gowtham")
public class DemoApplication {

    
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    @RestController
    public class controller {
        @GetMapping("/greet")
        public String hello() {
            return "HELLO";
        }
    }

The /greet route works

import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ccc {
    
    @GetMapping("/gg")
    public String hello() {
        return "HELLO";
        }
    }

But this route /gg which is inside .controller package which is under the main package doesn't work i tried moving the class "ccc" inside the main package and i also tried to scan base packages but no use

if i import the same program in other computers it is running fine

Package Structure

I'm also facing the same issue as mentioned above. I tried using Spring Boot version 2.7.9 instead of 3.0.3. It worked fine, although not sure what changed in the new version.

Make sure that your Spring Boot application is scanning the correct packages for your controllers. You can specify the base package for component scanning by adding the @ComponentScan annotation to your main class.

@SpringBootApplication
@ComponentScan(basePackages = "com.gowtham")
public class DemoApplication {
    // ...
}
