本文档介绍了如何使用Spring Boot进行邮件发送，包括发送简单邮件、复杂邮件以及自定义发送方法，涵盖了JavaMailSender接口、MimeMessage、MimeMessageHelper和附件处理等关键知识点。

package com.example;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

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

@SpringBootTest
class SpringbootTestApplicationTests {

    @Autowired
    JavaMailSenderImpl mailSender;
    @Test
    void contextLoads() {

        // 一个简单的邮件
        SimpleMailMessage mailMessage = new SimpleMailMessage();

        mailMessage.setSubject("法外狂徒张三");
        mailMessage.setText("daad");

        mailMessage.setTo("24736743@qq.com");
        mailMessage.setFrom("24736743@qq.com");


        mailSender.send(mailMessage);
    }


    @Test
    void contextLoads1() throws MessagingException {

        // 一个复杂的邮件
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        //组装
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);

        // 正文
        helper.setSubject("sasda");
        helper.setText("<p>dasdadad</p>",true);


        // 附件
        helper.addAttachment("1.jpg",new File(""));

        mailSender.send(mimeMessage);

    }
