Java应用程序抽取随机数据并通过qq邮箱发送结果(example:中午吃饭吃什么抽取，并发送到多个邮箱)

代码很简单，两个方法：随机方法、发送邮件方法。如果需要更改随机方法，直接将方法重写即可。

代码：

package com.eat;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

    private static final String[] options = {
    
    "面", "小厨", "乡村基", "米线", "粉", "小碗菜"};
    private static final String recipient1 = "[email protected]";
    // 多个邮箱配置到这里
    private static final String recipient2 = "[email protected]";
    private static final String recipient3 = "[email protected]";

	// 发送邮箱的配置
    private static final String sender = "[email protected]";
    // smtp密钥，不是邮箱密码，不懂自己百度
    private static final String password = "klbkixshfssbcaia";
    private static final String host = "smtp.qq.com";

    public static void main(String[] args) {
    
    
        // 获取吃什么
        String selectedOption = getRandomOption();
        // 发送邮箱
        sendEmail(selectedOption, recipient1, recipient2, recipient3);
    }

    private static String getRandomOption() {
    
    
        List<String> optionList = new ArrayList<>();
        Collections.addAll(optionList, options);
        Collections.shuffle(optionList);

        return optionList.get(0);
    }

    private static void sendEmail(String selectedOption, String... recipients) {
    
    
        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.ssl.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.port", "465");

        Session session = Session.getInstance(props,
                new Authenticator() {

                    }
                });

        try {
    
    
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(sender));
            InternetAddress[] addresses = new InternetAddress[recipients.length];
            for (int i = 0; i < recipients.length; i++) {
    
    
                addresses[i] = new InternetAddress(recipients[i]);
            }
            message.setRecipients(Message.RecipientType.TO, addresses);
            message.setSubject("午餐吃什么抽取结果");
            message.setText("今天我们吃：" + selectedOption + "。冲冲冲！");
            Transport.send(message);
            System.out.println("邮件发送成功！");
        } catch (Exception e) {
    
    
            System.out.println("邮件发送失败！");
            e.printStackTrace();
        }
    }
}
