required a bean of type 'org.springframework.mail.javamail.JavaMailSender

  1. Ensure that the required Spring Framework and Spring Boot dependencies are included in the project's build configuration.

  2. Create a configuration class annotated with @Configuration to define the JavaMailSender bean.

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;

public class MailConfig {

    public JavaMailSender javaMailSender() {
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        // Configure mailSender properties (host, port, username, password, etc.)
        return mailSender;
  1. Customize the properties of the JavaMailSender bean within the javaMailSender() method, setting the appropriate values for your mail server.

  2. Ensure that the necessary mail server connection details such as host, port, username, and password are provided in the configuration.

  3. If required, additional properties such as protocol, default encoding, and session properties can be configured within the javaMailSender() method.

  4. Inject the JavaMailSender bean into the components or services where email functionality is needed.

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

public class EmailService {

    private final JavaMailSender javaMailSender;

    public EmailService(JavaMailSender javaMailSender) {
        this.javaMailSender = javaMailSender;

    // Implement email sending functionality using javaMailSender
  1. Utilize the injected JavaMailSender bean within the EmailService or other components to send emails as needed.

Note: The provided code snippets are simplified examples, and actual configuration may vary based on the specific requirements and environment of the project.
