16- Create JPA Employee (Model or Entity) and Repository

 

Creating Employee Model

springboot-backendd  --> src/main/java --> net.javaguides.springboot.model --> Employee.java

package net.javaguides.springboot.model;

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="employees")

public class Employee {

   

    @Id

    @GeneratedValue(strategy=GenerationType.IDENTITY)

    private long id;

   

    @Column(name="first_name",nullable=false)

    private String firstName;

   

    @Column(name="last_name")

    private String lastName;

   

    @Column(name="email")

    private String email;

   

     //Constructors using superclass

    public Employee(){

       

    }

   

   

     //Constructors using field

    public Employee( String firstName, String lastName, String email) {

        super();

       

        this.firstName = firstName;

        this.lastName = lastName;

        this.email = email;

    }

   

    //Getters and Setters

   

    public long getId() {

        return id;

    }

    public void setId(long id) {

        this.id = id;

    }

    public String getFirstName() {

        return firstName;

    }

    public void setFirstName(String firstName) {

        this.firstName = firstName;

    }

    public String getLastName() {

        return lastName;

    }

    public void setLastName(String lastName) {

        this.lastName = lastName;

    }

    public String getEmail() {

        return email;

    }

    public void setEmail(String email) {

        this.email = email;

    }

}

Creating Employee Repository

springboot-backendd --> src/main/java--> net.javaguides.springboot.repository-->  EmployeeRepository.java

package net.javaguides.springboot.repository;

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

import net.javaguides.springboot.model.Employee;

/*Spring Data JPA internally provides @Repository Annotations so we no need

   to add @Repository annotation to Employee Repository interface*/

public interface EmployeeRepository extends JpaRepository <Employee,Long> {

}
