    @Override

        SimpleMailMessage message = new SimpleMailMessage();

        // 设置发送右键的内容
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(context);
        javaMailSender.send(message);

package com.ustc;

import com.ustc.service.SendService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Quick3ApplicationTests {

    @Autowired
    private SendService sendservice;// 注入接口

    @Test
    void contextLoads() {

        sendservice.sendMail();// 接口调用方法
    }

}

JavaMail发送多部件邮件

    @Override
    public void sendMail() throws MessagingException {
//        SimpleMailMessage message = new SimpleMailMessage();

        MimeMessage m =  javaMailSender.createMimeMessage();
        MimeMessageHelper message = new MimeMessageHelper(m);

        // 设置发送右键的内容
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(context);

        // 添加附件
        File f1 = new File("D:\\1.txt");
        message.addAttachment(f1.getName(),f1);

        javaMailSender.send(message);

    }
