springboot实现邮件发送

好的，以下是使用Spring Boot实现邮件发送的步骤：

1. 配置邮件发送参数

在 `application.properties` 或 `application.yml` 文件中配置邮件发送的参数，例如：

spring.mail.host=smtp.example.com
spring.mail.port=587
spring.mail.username=your-username
spring.mail.password=your-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

2. 添加邮件依赖

在 `pom.xml` 文件中添加邮件相关的依赖，例如：

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

3. 编写邮件发送服务

在代码中编写邮件发送服务，例如：

@Service
public class EmailService {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendSimpleEmail(String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        javaMailSender.send(message);
    }

    public void sendHtmlEmail(String to, String subject, String html) {
        MimeMessage message = javaMailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(html, true);
            javaMailSender.send(message);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

    public void sendAttachmentEmail(String to, String subject, String text, File file) {
        MimeMessage message = javaMailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(text);
            helper.addAttachment(file.getName(), file);
            javaMailSender.send(message);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

}

4. 调用邮件发送服务

在需要发送邮件的地方调用邮件发送服务即可，例如：

@Autowired
private EmailService emailService;

public void sendEmail() {
    String to = "example@example.com";
    String subject = "Test Email";
    String text = "This is a test email.";

    emailService.sendSimpleEmail(to, subject, text);
}

以上就是使用Spring Boot实现邮件发送的步骤，希望能对你有所帮助。
