how to fetch email and get there body content in spring boot

To fetch emails and retrieve their body content in a Spring Boot application, you can use the JavaMail API along with the Spring Framework's JavaMailSender. Here is a step-by-step guide:

Step 1: Add Dependencies Make sure you have the necessary dependencies in your project's build file (pom.xml for Maven or build.gradle for Gradle). You will need the following dependencies:




implementation 'org.springframework.boot:spring-boot-starter-mail'

Step 2: Configure Email Properties In your or application.yml file, configure the necessary email properties such as the host, port, username, and password. Here is an example for Gmail:
[email protected]

Step 3: Create a Service or Component Create a service or component class to handle email retrieval. Inject the JavaMailSender bean provided by Spring.

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

public class EmailService {

    private JavaMailSender javaMailSender;

    // Your methods for fetching and processing emails


Step 4: Fetch Emails Inside your EmailService class, you can define methods to fetch emails. Use the JavaMailSender's receive() method to retrieve emails from a mailbox. You can specify the folder and search criteria to filter the emails you want to fetch. Here is an example:

import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import org.springframework.stereotype.Service;

public class EmailService {

    // ...

    public void fetchEmails() throws MessagingException {
        Folder inbox = javaMailSender.getFolder("INBOX");;

        Message[] messages = FlagTerm(new Flags(Flags.Flag.SEEN), false));

        for (Message message : messages) {
            // Process each email message
            String subject = message.getSubject();
            String body = message.getContent().toString();

            // Do something with the subject and body



In this example, we fetch unread emails from the INBOX folder and process them. You can access the subject and body content of each email using the Message object.

Step 5: Handle Exceptions Remember to handle any exceptions that may occur during the email fetching process, such as MessagingException. You can either catch the exception and handle it within the method or propagate it to the caller.

And that's it! You now have a basic understanding of how to fetch emails and retrieve their body content in a Spring Boot application. Feel free to customize and extend this functionality based on your specific requirements.
