In the world of software development, sending emails is a common task. It’s like sending a message in a bottle, hoping it reaches the right person. Today, we’ll explore how to set up email sending using Yandex with Spring Boot. This combination is powerful and efficient, allowing developers to integrate email functionality seamlessly into their applications.

First, let’s talk about the essentials. You need a Yandex email account. Think of it as your mailbox in the digital world. Without it, you can’t send emails. Once you have your account, the next step is to create an application password. This password acts like a key, granting your application access to your mailbox. It’s crucial to copy this password when you create it, as it will only be visible once.

Now, let’s dive into the Spring Boot project. If you’re familiar with Spring Boot, you know it’s a framework that simplifies Java development. It’s like a well-organized toolbox, ready to help you build applications efficiently. Ensure you have your project set up and ready to go.

To send emails, you need to add a dependency for email functionality. If you’re using Gradle, you’ll add the following line to your `build.gradle` file:

```groovy
implementation("org.springframework.boot:spring-boot-starter-mail:3.1.5")
```

This dependency is like adding a new tool to your toolbox. It provides the necessary components to handle email sending.

Next, you need to configure your application. This is where you set the parameters for your email service. Open the `application.properties` file and add the following configurations:

```properties
spring.mail.host=smtp.yandex.ru
spring.mail.port=465
spring.mail.protocol=smtps
spring.mail.username=your_yandex_login
spring.mail.password=your_yandex_password
mail.debug=false
```

These settings tell Spring Boot how to connect to Yandex’s SMTP server. It’s like giving directions to a delivery person. Make sure to replace `your_yandex_login` and `your_yandex_password` with your actual Yandex credentials.

Now, it’s time to create a JavaMailSender implementation. This class will handle the actual sending of emails. Here’s how you can set it up:

```kotlin
import org.springframework.beans.factory.annotation.Value
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.mail.javamail.JavaMailSender
import org.springframework.mail.javamail.JavaMailSenderImpl

@Configuration
class MailConfig {
@Value("\${spring.mail.host}")
private val host: String? = null

@Value("\${spring.mail.username}")
private val username: String? = null

@Value("\${spring.mail.password}")
private val password: String? = null

@Value("\${spring.mail.port}")
private val port: Int = 0

@Value("\${spring.mail.protocol}")
private val protocol: String? = null

@Value("\${mail.debug}")
private val debug: String? = null

@Bean
fun getMailSender(): JavaMailSender {
val mailSender = JavaMailSenderImpl()
mailSender.host = host
mailSender.port = port
mailSender.username = username
mailSender.password = password

val properties = mailSender.javaMailProperties
properties.setProperty("mail.transport.protocol", protocol)
properties.setProperty("mail.debug", debug)

return mailSender
}
}
```

This configuration class is the heart of your email functionality. It sets up the JavaMailSender with the necessary properties. It’s like assembling a machine; each part must fit perfectly for it to work.

Next, you need a class to send emails. Let’s call it `MailSender`. This class will use the JavaMailSender to send messages. Here’s a simple implementation:

```kotlin
import org.springframework.beans.factory.annotation.Value
import org.springframework.mail.SimpleMailMessage
import org.springframework.mail.javamail.JavaMailSender
import org.springframework.stereotype.Service

@Service
class MailSender(private val mailSender: JavaMailSender) {
@Value("\${spring.mail.username}")
private val username: String? = null

fun send(emailTo: String, subject: String, message: String) {
val mailMessage = SimpleMailMessage()
mailMessage.from = username
mailMessage.setTo(emailTo)
mailMessage.subject = subject
mailMessage.text = message
mailSender.send(mailMessage)
}
}
```

This class is your email sender. It takes the recipient's email, subject, and message as parameters. When you call the `send` method, it constructs an email and sends it off. It’s like writing a letter and dropping it in the mailbox.

With everything set up, you can now send emails from your application. This functionality opens doors for various use cases, such as user notifications, password resets, and confirmations. It’s a powerful tool in your development arsenal.

In conclusion, integrating Yandex email with Spring Boot is straightforward. With just a few steps, you can set up a reliable email-sending mechanism. This process is not just about sending messages; it’s about enhancing user experience and communication. So, roll up your sleeves and start sending those emails!
