In this Article explains Spring boot Login and Registration Rest API Project. and how to set the hash password for the login spring boot security example step by step.database we are using Mysql. spring boot rest api log request and response very easy way.spring boot login page we tested through postman tool.
Lets follow the following step
First you have add the following dependencies while you configuring the spring initializr.
- spring jpa
- spring web
- spring security
- mysql
Open the project on the pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-connector-j</artifactId>
<scope>runtime</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-security -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
<version>2.7.8</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependencies>you see the dependencies what you added.
Create the Mysql Database and Configure the database connection in the application.properties. this place where connect to Spring boot to Mysql.
application.properties
spring.application.name=Registation server.port=8085 spring.jpa.hibernate.ddl-auto=create spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/dbkms?createDatabaseIfNotExist=true spring.datasource.username=root spring.datasource.password=root123 #jpa vendor adapter configuration spring.jpa.database-platform=org.hibernate.dialect.MySQL57Dialect spring.jpa.generate-ddl=true spring.jpa.show-sql=true
Create the Entity Employee for represent the employee data in the database.
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="email", length = 255)
private String email;
@Column(name="password", length = 255)
private String password;
public Employee() {
}
public Employee(int employeeid, String employeename, String email, String password) {
this.employeeid = employeeid;
this.employeename = employeename;
this.email = email;
this.password = password;
}
//create getters and settersEmployeeDTO
public class EmployeeDTO {
private int employeeid;
private String employeename;
private String email;
private String password;
public EmployeeDTO() {
}
public EmployeeDTO(int employeeid, String employeename, String email, String password) {
this.employeeid = employeeid;
this.employeename = employeename;
this.email = email;
this.password = password;
}
} //create getters and settersLoginDTO
public class LoginDTO {
private String email;
private String password;
public LoginDTO() {
}
public LoginDTO(String email, String password) {
this.email = email;
this.password = password;
} //create getters and settersCreate a EmployeeRepository interface which extends JpaRepository
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;
import java.util.Optional;
@EnableJpaRepositories
@Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer>
{
Optional<Employee> findOneByEmailAndPassword(String email, String password);
Employee findByEmail(String email);
}Create the Employee Service
EmployeeService
package com.example.Registation.Service;
import com.example.Registation.Dto.EmployeeDTO;
import com.example.Registation.Dto.LoginDTO;
import com.example.Registation.payload.response.LoginMesage;
public interface EmployeeService {
String addEmployee(EmployeeDTO employeeDTO);
LoginMesage loginEmployee(LoginDTO loginDTO);
}Create the EmployeeImpl which implements from EmployeeService
EmployeeImpl
package com.example.Registation.Service.impl;
import com.example.Registation.Dto.EmployeeDTO;
import com.example.Registation.Dto.LoginDTO;
import com.example.Registation.Entity.Employee;
import com.example.Registation.Repo.EmployeeRepo;
import com.example.Registation.Service.EmployeeService;
import com.example.Registation.payload.response.LoginMesage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.Optional;
@Service
public class EmployeeIMPL implements EmployeeService {
@Autowired
private EmployeeRepo employeeRepo;
@Autowired
private PasswordEncoder passwordEncoder;
@Override
public String addEmployee(EmployeeDTO employeeDTO) {
Employee employee = new Employee(
employeeDTO.getEmployeeid(),
employeeDTO.getEmployeename(),
employeeDTO.getEmail(),
this.passwordEncoder.encode(employeeDTO.getPassword())
);
employeeRepo.save(employee);
return employee.getEmployeename();
}
EmployeeDTO employeeDTO;
@Override
public LoginMesage loginEmployee(LoginDTO loginDTO) {
String msg = "";
Employee employee1 = employeeRepo.findByEmail(loginDTO.getEmail());
if (employee1 != null) {
String password = loginDTO.getPassword();
String encodedPassword = employee1.getPassword();
Boolean isPwdRight = passwordEncoder.matches(password, encodedPassword);
if (isPwdRight) {
Optional<Employee> employee = employeeRepo.findOneByEmailAndPassword(loginDTO.getEmail(), encodedPassword);
if (employee.isPresent()) {
return new LoginMesage("Login Success", true);
} else {
return new LoginMesage("Login Failed", false);
}
} else {
return new LoginMesage("password Not Match", false);
}
}else {
return new LoginMesage("Email not exits", false);
}
}
}Create a EmployeeController to manage the Restful api requests related to employee login and registration.spring boot login example i explained with clear code snippet.
EmployeeController
package com.example.RegisterLogin.EmployeeController;
import com.example.RegisterLogin.Dto.EmployeeDTO;
import com.example.RegisterLogin.Dto.LoginDTO;
import com.example.RegisterLogin.Service.EmployeeService;
import com.example.RegisterLogin.response.LoginResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
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;
}
@PostMapping(path = "/login")
public ResponseEntity<?> loginEmployee(@RequestBody LoginDTO loginDTO)
{
LoginResponse loginResponse = employeeService.loginEmployee(loginDTO);
return ResponseEntity.ok(loginResponse);
}
}Spring boot security example
Security measures need to implemented
Create a file SecurityConfig for managing the Security password
package com.example.Registation.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
@Configuration
public class SecurityConfig {
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}Create LoginResponse Page for displaying Messages while testing
LoginResponse
public class LoginMesage {
String message;
Boolean status;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Boolean getStatus() {
return status;
}
public void setStatus(Boolean status) {
this.status = status;
}
public LoginMesage(String message, Boolean status) {
this.message = message;
this.status = status;
}
