In this tutorials will teach you how to do the Restful API to add the records in to the mysql database.how to insert the records into mysql database step by step via spring boot layer architecture process using industrial standards.

Create the Package entity inside the package create the class Employee

Employee

package com.example.Registation.Entity;
import javax.persistence.*;

@Entity
@Table(name="employee")
public class Employee 
{
    @Id
    @Column(name="employee_id", length = 45)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int employeeid;

    @Column(name="employee_name", length = 255)
    private String employeename;

    @Column(name="address", length = 255)
    private String address;

    @Column(name="mobile", length = 20)
    private int mobile;

    public Employee(int employeeid, String employeename, String address, int mobile) {
        this.employeeid = employeeid;
        this.employeename = employeename;
        this.address = address;
        this.mobile = mobile;
    }

    public Employee() {
    }

    public int getEmployeeid() {
        return employeeid;
    }

    public void setEmployeeid(int employeeid) {
        this.employeeid = employeeid;
    }

    public String getEmployeename() {
        return employeename;
    }

    public void setEmployeename(String employeename) {
        this.employeename = employeename;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getMobile() {
        return mobile;
    }

    public void setMobile(int mobile) {
        this.mobile = mobile;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "employeeid=" + employeeid +
                ", employeename='" + employeename + '\'' +
                ", address='" + address + '\'' +
                ", mobile=" + mobile +
                '}';
    }
}

package com.example.Registation.Entity;

import javax.persistence.*;

@Entity

@Table(name="employee")

public class Employee

{

@Id

@Column(name="employee_id", length = 45)

@GeneratedValue(strategy = GenerationType.AUTO)

private int employeeid;

@Column(name="employee_name", length = 255)

private String employeename;

@Column(name="address", length = 255)

private String address;

@Column(name="mobile", length = 20)

private int mobile;

public Employee(int employeeid, String employeename, String address, int mobile) {

this.employeeid = employeeid;

this.employeename = employeename;

this.address = address;

this.mobile = mobile;

}

public Employee() {

}

public int getEmployeeid() {

return employeeid;

}

public void setEmployeeid(int employeeid) {

this.employeeid = employeeid;

}

public String getEmployeename() {

return employeename;

}

public void setEmployeename(String employeename) {

this.employeename = employeename;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public int getMobile() {

return mobile;

}

public void setMobile(int mobile) {

this.mobile = mobile;

}

@Override

public String toString() {

return "Employee{" +

"employeeid=" + employeeid +

", employeename='" + employeename + '\'' +

", address='" + address + '\'' +

", mobile=" + mobile +

'}';

}

Create the Package Dt0 inside the package create the class EmployeeDTO

EmployeeDTO

package com.example.Registation.Dto;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

public class EmployeeDTO {


    private int employeeid;
    private String employeename;
    private String address;
    private int mobile;

    public EmployeeDTO(int employeeid, String employeename, String address, int mobile) {
        this.employeeid = employeeid;
        this.employeename = employeename;
        this.address = address;
        this.mobile = mobile;
    }

    public EmployeeDTO() {
    }

    public int getEmployeeid() {
        return employeeid;
    }

    public void setEmployeeid(int employeeid) {
        this.employeeid = employeeid;
    }

    public String getEmployeename() {
        return employeename;
    }

    public void setEmployeename(String employeename) {
        this.employeename = employeename;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getMobile() {
        return mobile;
    }

    public void setMobile(int mobile) {
        this.mobile = mobile;
    }

    @Override
    public String toString() {
        return "EmployeeDTO{" +
                "employeeid=" + employeeid +
                ", employeename='" + employeename + '\'' +
                ", address='" + address + '\'' +
                ", mobile=" + mobile +
                '}';
    }
}

package com.example.Registation.Dto;

import javax.persistence.Column;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

public class EmployeeDTO {

private int employeeid;

private String employeename;

private String address;

private int mobile;

public EmployeeDTO(int employeeid, String employeename, String address, int mobile) {

this.employeeid = employeeid;

this.employeename = employeename;

this.address = address;

this.mobile = mobile;

}

public EmployeeDTO() {

}

public int getEmployeeid() {

return employeeid;

}

public void setEmployeeid(int employeeid) {

this.employeeid = employeeid;

}

public String getEmployeename() {

return employeename;

}

public void setEmployeename(String employeename) {

this.employeename = employeename;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public int getMobile() {

return mobile;

}

public void setMobile(int mobile) {

this.mobile = mobile;

}

@Override

public String toString() {

return "EmployeeDTO{" +

"employeeid=" + employeeid +

", employeename='" + employeename + '\'' +

", address='" + address + '\'' +

", mobile=" + mobile +

'}';

}

Create the Package Controller inside the package create the class EmployeeController

EmployeeController

package com.example.Registation.EmployeeController;
import com.example.Registation.Dto.EmployeeDTO;
import com.example.Registation.Service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@CrossOrigin
@RequestMapping("api/v1/employee")
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    @PostMapping(path = "/save")
    public String saveEmployee(@RequestBody EmployeeDTO employeeDTO)
    {
        String id = employeeService.addEmployee(employeeDTO);
        return id;
    }
}

package com.example.Registation.EmployeeController;

import com.example.Registation.Dto.EmployeeDTO;

import com.example.Registation.Service.EmployeeService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.*;

@RestController

@CrossOrigin

@RequestMapping("api/v1/employee")

public class EmployeeController {

@Autowired

private EmployeeService employeeService;

@PostMapping(path = "/save")

public String saveEmployee(@RequestBody EmployeeDTO employeeDTO)

{

String id = employeeService.addEmployee(employeeDTO);

return id;

}

Create the Package Service inside the package create the one class EmployeeServiceIMPL and create one interface EmployeeService

Employee Service

package com.example.Registation.Service;

import com.example.Registation.Dto.EmployeeDTO;

public interface EmployeeService {
    String addEmployee(EmployeeDTO employeeDTO);
}

package com.example.Registation.Service;

import com.example.Registation.Dto.EmployeeDTO;

public interface EmployeeService {

String addEmployee(EmployeeDTO employeeDTO);

}

EmployeeServiceIMPL

package com.example.Registation.Service.impl;
import com.example.Registation.Dto.EmployeeDTO;
import com.example.Registation.Entity.Employee;
import com.example.Registation.Repo.EmployeeRepo;
import com.example.Registation.Service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class EmployeeIMPL implements EmployeeService 
 {
    @Autowired
    private EmployeeRepo employeeRepo;
    @Override
    public String addEmployee(EmployeeDTO employeeDTO) 
       {

        Employee employee = new Employee(
                employeeDTO.getEmployeeid(),
                employeeDTO.getEmployeename(),
                employeeDTO.getAddress(),
                employeeDTO.getMobile()
        );
        employeeRepo.save(employee);
        return employee.getEmployeename();
    }
}

package com.example.Registation.Service.impl;

import com.example.Registation.Dto.EmployeeDTO;

import com.example.Registation.Entity.Employee;

import com.example.Registation.Repo.EmployeeRepo;

import com.example.Registation.Service.EmployeeService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

@Service

public class EmployeeIMPL implements EmployeeService

{

@Autowired

private EmployeeRepo employeeRepo;

@Override

public String addEmployee(EmployeeDTO employeeDTO)

{

Employee employee = new Employee(

employeeDTO.getEmployeeid(),

employeeDTO.getEmployeename(),

employeeDTO.getAddress(),

employeeDTO.getMobile()

);

employeeRepo.save(employee);

return employee.getEmployeename();

}

Create the Package EmployeeRepo inside the package create one interface EmployeeRepo

EmployeeRepo

package com.example.Registation.Repo;

import com.example.Registation.Entity.Employee;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.stereotype.Repository;

@EnableJpaRepositories
@Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer> {
}

package com.example.Registation.Repo;

import com.example.Registation.Entity.Employee;

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

import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import org.springframework.stereotype.Repository;

@EnableJpaRepositories

@Repository

public interface EmployeeRepo extends JpaRepository<Employee,Integer> {

}

then run the Back-end Spring Boot Application.
