当满足arduino ide中的条件时，使用java发送电子邮件

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

public class EmailSender {
    public static void main(String[] args) {
        // 设置SMTP服务器地址和端口号
        String smtpServer = "your_smtp_server";
        int smtpPort = 25;

        // 发件人邮箱和密码
        String fromEmail = "your_email@example.com";
        String password = "your_password";

        // 收件人邮箱
        String toEmail = "recipient@example.com";

        // 创建邮件会话
        Properties props = new Properties();
        props.put("mail.smtp.host", smtpServer);
        props.put("mail.smtp.port", smtpPort);
        props.put("mail.smtp.auth", "true");

        // 使用身份验证
        Session session = Session.getDefaultInstance(props,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(fromEmail, password);
                }
            });

        try {
            // 创建邮件对象
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(fromEmail));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(toEmail));
            message.setSubject("Test Email");
            message.setText("This is a test email from Java.");

            // 发送邮件
            Transport.send(message);

            System.out.println("Email sent successfully.");
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}
