package net.javaguides.springboot.entity;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;

@Entity

@Table(name="students")

public class Student {

   

    @Id

    @GeneratedValue(strategy=GenerationType.IDENTITY)

    private long id;

package net.javaguides.springboot.repository;

import org.springframework.data.jpa.repository.JpaRepository;

import net.javaguides.springboot.entity.Student;
