### 一、发送邮箱工具类 ###

import com.sun.mail.util.MailSSLSocketFactory;
    import org.springframework.stereotype.Component;
    
    import java.util.*;
    import javax.mail.*;
    import javax.mail.internet.*;
    
    import java.util.Properties;
    
    
    /**

    @Component
    public class SendMailUtil {
        
    
        public static String myEmailAccount = "879466586@qq.com";//发件人邮箱-我的QQ
        public static String myEmailPassword = "siuayhquejijbceb";//授权码-我的QQ
        public static String myEmailSMTPHost = "smtp.qq.com";
    
        public static int sendMail(String username,String cEmail,String subject,String content) throws Exception{
        
            int createMimeMessage = 0;
    
            //1.创建参数配置, 用于连接邮件服务器的参数配置
            Properties props = new Properties();//参数配置
            props.setProperty("mail.transport.protocol", "smtp");// 使用的协议（JavaMail规范要求）
            props.setProperty("mail.smtp.host", myEmailSMTPHost);// 发件人的邮箱的 SMTP 服务器地址
            props.setProperty("mail.smtp.auth", "true");// 需要请求认证
    
            //2.根据配置创建会话对象, 用于和邮件服务器交互
            Session session = Session.getInstance(props);
            session.setDebug(true);//设置为debug模式, 可以查看详细的发送 log
    
            //3.创建一封邮件
            MimeMessage message = new MimeMessage(session);
    
            //4.发件人：发件人邮箱、发件人昵称
            message.setFrom(new InternetAddress(myEmailAccount, username, "UTF-8"));
    
            //5.收件人：收件人邮箱、收件人名称
            message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(cEmail, "进", "UTF-8"));
    
            //6.邮件主题
            message.setSubject(subject, "UTF-8");
    
            //7.邮件内容：可以使用html标签
            //content = "<a href='https://www.hao123.com/'>点击</a>";
            message.setContent(content, "text/html;charset=UTF-8");
    
            //8.设置发件时间
            message.setSentDate(new Date());
    
            //9.保存设置
            message.saveChanges();
    
            //10.根据 Session 获取邮件传输对象
            Transport transport = session.getTransport();
    
            //11.使用 邮箱账号 和 密码 连接邮件服务器, 这里认证的邮箱必须与 message 中的发件人邮箱一致, 否则报错
            transport.connect(myEmailAccount, myEmailPassword);
    
            //12.发送邮件, 发到所有的收件地址, message.getAllRecipients() 获取到的是在创建邮件对象时添加的所有收件人, 抄送人, 密送人
            transport.sendMessage(message, message.getAllRecipients());
    
            //13.关闭连接
            transport.close();
    
            createMimeMessage = 1;
            return createMimeMessage;
        }
    }
