As per the exception you can see while creating beans you are getting error. This is because you have used @EntityScan so, IOC will scan only the class which will have @Entity and only those bean will be available in IOC. And it will not scan all other classes and bean of other classes will not generate in IOC. So, for making this application to work you must use @ComponentScan

You can read about the differences of @EntityScan and @ComponentScan here differences

With that version of Java and Spring Boot you should be using the jakarta library and not javax. Remove the javax dependency, remove @EntityScan, and refactor your Employee class to use the jakarta library and that should fix things and make Employee discoverable by @SpringBootApplication.

As rightly mentioned by @TimurCelikel, solution is to,

  1. Replace javax.persistence with jakarta.persistence
  2. Remove @EntityScan("com.example.demo.model")

UPDATED ENTITY CLASS

package com.example.demo.model;

import jakarta.persistence.Entity;
import jakarta.persistence.Column;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.Table;

Service class

package com.example.demo.service;

import com.example.demo.repository.EmployeeRepository;
import com.example.demo.model.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class EmployeeService {

    EmployeeRepository empRepo;

    @Autowired
    public EmployeeService(EmployeeRepository empRepo) {
        this.empRepo = empRepo;
    }
    public List<Employee> getEmployees() {
        return empRepo.findAll();
    }
}
