8. Build Create Employee REST API

EmployeeService

package net.javaguides.springboot.service;

import net.javaguides.springboot.entity.Employee;

public interface EmployeeService {
    Employee createEmployee(Employee employee);
}

EmployeeServiceImpl

package net.javaguides.springboot.service.impl;

import lombok.AllArgsConstructor;
import net.javaguides.springboot.entity.Employee;
import net.javaguides.springboot.repository.EmployeeRepository;
import net.javaguides.springboot.service.EmployeeService;
import org.springframework.stereotype.Service;

@Service
@AllArgsConstructor
public class EmployeeServiceImpl implements EmployeeService {

    private EmployeeRepository employeeRepository;

    @Override
    public Employee createEmployee(Employee employee) {
        return employeeRepository.save(employee);
    }
}

EmployeeController

package net.javaguides.springboot.controller;

import lombok.AllArgsConstructor;
import net.javaguides.springboot.entity.Employee;
import net.javaguides.springboot.service.EmployeeService;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@AllArgsConstructor
@RequestMapping("api/employees")
public class EmployeeController {

    private EmployeeService employeeService;

    @PostMapping
    public ResponseEntity<Employee> createEmployee(@RequestBody Employee employee){
        Employee savedEmployee = employeeService.createEmployee(employee);
