本文着重为大家仔细讲解了springboot实现发送邮件，qq邮箱代码实现邮件发送，文中代码实例讲解的非常细致，希望能够帮助到您，欢迎大家阅读和收藏

1.引入依赖

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-mail</artifactId>
<https://img.qb5200.com/download-x/dependency>

2.找到qq邮箱，开启smtp服务，这里生成你的密码，复制第三步用

3.password里输入你获取到的密码（重点：这里一定不能错）

spring.mail.username=1550213743@qq.com
spring.mail.password=********
spring.mail.host=smtp.qq.com
#开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

4.EmailApplicationTests类里进行测试， contextLoads为简单的发送，仅限于文本。contextLoads2为复杂，可以发送图片，html格式

package com.xyj;

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 EmailApplicationTests {

  @Autowired
  JavaMailSenderImpl mailSender;

  @Test
  void contextLoads() {
    SimpleMailMessage mailMessage = new SimpleMailMessage();
    mailMessage.setSubject("你好");
    mailMessage.setText("123456");
    mailMessage.setTo("1550213743@qq.com");
    mailMessage.setFrom("1550213743@qq.com");
    mailSender.send(mailMessage);
  }


  @Test
  void contextLoads2() throws MessagingException {
    MimeMessage mimeMessage = mailSender.createMimeMessage();
    MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);

    helper.setSubject("你好");
    helper.setText("<p style='color:red'>这是红色的</p>",true);
    helper.addAttachment("bg.jpg",new File("D:\\money\\网页\\疫情\\images\\bg1.jpg"));
    helper.setTo("1550213743@qq.com");
    helper.setFrom("1550213743@qq.com");
    mailSender.send(mimeMessage);
  }

}
