调用方法类

import lombok.extern.slf4j.Slf4j;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

@Component
@Slf4j
public class EmailSendMsgHandle {


    public void sendMsgOne(EmailAuthorization emailAuthorization, EmailMsgData emailMsgData){
        ArrayList<EmailMsgData> emailMsgDatas = new ArrayList<>();
        emailMsgDatas.add(emailMsgData);
        sendMsgBatch(emailAuthorization, emailMsgDatas);
    }


    public void sendMsgBatch(EmailAuthorization emailAuthorization, List<EmailMsgData> emailMsgDatas){
        log.info("发邮件");
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        if (null == emailAuthorization.getProperties()) {
            Properties properties = System.getProperties();
            properties.setProperty("mail.smtp.auth", "true");
            properties.setProperty("mail.smtp.host", emailAuthorization.getHost());//smtp服务器地址
            properties.setProperty("mail.smtp.from", emailAuthorization.getUsername());//mailfrom 参数
            properties.setProperty("mail.user",emailAuthorization.getUsername());//发件人的账号
            properties.setProperty("mail.password",emailAuthorization.getPassword());// 发件人的账号的密码，如果开启三方客户端安全密码请使用新生产的密码
            properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            properties.setProperty("mail.smtp.socketFactory.fallback", "false");
            properties.setProperty("mail.smtp.socketFactory.port", emailAuthorization.getPost());
            emailAuthorization.setProperties(properties);
        }
        mailSender.setDefaultEncoding("utf-8");
        mailSender.setJavaMailProperties(emailAuthorization.getProperties());
        mailSender.setHost(emailAuthorization.getHost());
        mailSender.setPassword(emailAuthorization.getPassword());
        mailSender.setUsername(emailAuthorization.getUsername());
        mailSender.setPort(Integer.parseInt(emailAuthorization.getPost()));
        MimeMessage message = mailSender.createMimeMessage();
        MimeMessageHelper helper = null;
        try {
            helper = new MimeMessageHelper(message, true);
            // 设置发送方邮箱地址
            helper.setFrom(emailAuthorization.getUsername());

            for (EmailMsgData emailMsgData : emailMsgDatas) {
                helper.setSubject(emailMsgData.getTitle());
                helper.setText(emailMsgData.getContent(), true);
                helper.setTo(emailMsgData.getTo());
                mailSender.send(message);
            }
        } catch (MessagingException e) {
            e.printStackTrace();
         
        }
    }
}

调用

@Autowired private EmailSendMsgHandle emailSendMsgHandle;

//授权参数装配

EmailAuthorization emailAuthorization = new EmailAuthorization();
//发送参数装配
EmailMsgData emailMsgData = new EmailMsgData();
//发送
emailSendMsgHandle.sendMsgOne(emailAuthorization,emailMsgData);
