This is a latest guide on how to send Email in your SpringBoot Application. Simply follow these steps to make your Spring Application be able to send Email.

Step 1: Add Project Dependency

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

Step 2: Set up App Password inside your Google Account

Go to (Google Account)[https://myaccount.google.com]
On Search Bar, search for App Passwords then you should see App Passwords with Security under it
Under Select App, find Other (Custom Name), input your desired name then click Generate
Copy the password we will use it later

Step 3: Set up Application.properties

spring.mail.username=youremail@gmail.com
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.password=Copied Password From App Password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.transport.protocol=smtp
spring.mail.properties.mail.smtp.starttls.enable=true

Step 4: Configure Bean for JavaMailSender

@Configuration
public class MailConfiguration {

    @Bean
    public JavaMailSender getJavaMailSender() {
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        mailSender.setHost("smtp.gmail.com");
        mailSender.setPort(587);

        mailSender.setUsername("your@gmail.com");
        mailSender.setPassword("copiedPassword");

        Properties props = mailSender.getJavaMailProperties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.debug", "true");

        return mailSender;
    }
}

Step 5: Implement MailSenderService

@Service
public class MailSenderService {
    @Autowired
    private JavaMailSender mailSender;

    public void sendNewMail(String to, String subject, String body) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(body);
        mailSender.send(message);
    }
}

Step 6: Start sending email

private final MailSenderService mailService;

public void Foo(){
 mailService.sendNewMail("test@gmail.com", "Subject right here", "Body right there!")
}
