添加依赖

        <!--    电子邮件    -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>

编码

为了方便直接在控制层写了

package com.takem.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

@RestController
public class EmailController {

    @Autowired
    private JavaMailSender mailSender;

    @GetMapping("/email")
    public String sendSimpleMessage() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true); 
        helper.setFrom("你的邮箱");
        helper.setTo("对方的邮箱");
        helper.setSubject("测试标题");
        helper.setText("测试内容");
        // 添加文件
        helper.addAttachment("文件名(包含后缀名)", new File("文件的路径(写死都没事)"));
        mailSender.send(mimeMessage);
        return "发送成功";
    }
}
