Spring Boot中使用JavaMailSender发送邮件

import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service
public class EmailService {
 
    private final JavaMailSender mailSender;
 
    @Autowired
    public EmailService(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }
 
    public void sendSimpleMail(String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
 
        mailSender.send(message);
    }
}

这段代码定义了一个EmailService类，它使用JavaMailSender来发送简单邮件。sendSimpleMail方法接受收件人地址、邮件主题和邮件内容作为参数，创建一个SimpleMailMessage对象，并设置这些参数，最后调用mailSender.send(message)发送邮件。这个类可以在Spring Boot应用中注入并使用，用于发送各种通知或验证邮件等。
