SpringBoot发送邮件

1 获取QQ的SMTP授权码

 

 

 

2 导入依赖

     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

 

 3 application.yml加入配置

mail:
  username: 1198247262@qq.com
  # 这个密码就是smtp授权码
  password: sobaxyrlqmxcgiib
  # host如果是qq就写qq，163就写163
  host: smtp.qq.com
  # 开启加密验证（这个只有qq有）
  properties:
    mail:
      smtp:
        ssl:
          enable: true

 

4编写测试类

package com.tan.sendMail;

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.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

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

/**

 */
@SpringBootTest
public class SendMailTest {
    @Autowired
    JavaMailSenderImpl javaMailSender;

    //简单邮件
    @Test
    public void sendMail() {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        //标题
        mailMessage.setSubject("测试发邮件");
        mailMessage.setText("邮件正文");
        //发送方
        mailMessage.setFrom("119847262@qq.com");
        //接收方
        mailMessage.setTo("85267635@qq.com");
        javaMailSender.send(mailMessage);
    }

    //复杂邮件
    @Test
    public void sendMail2() {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
            //标题
            helper.setSubject("这是title");
            // true 表示解析支持html
            helper.setText("<p style='color:red'>邮件正文内容！</p>", true);
            // 附件
            helper.addAttachment("小姐姐.jpg", new File("C:\\Users\\Administrator\\Pictures\\getImg.jpg"));
            // 发送方
            helper.setFrom("1198247262@qq.com");
            //接收方
            helper.setTo("857267635@qq.com");
            javaMailSender.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}
