### 一、邮件发送需要引入spring-boot-starter-mail ###

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

### 二、配置邮件发送相关参数 ###

spring.mail.username=QQ邮箱
    spring.mail.password=授权码
    spring.mail.host=smtp.qq.com
    #如果提示不是SSL安全连接,加上该配置
    spring.mail.properties.mail.smtp.ssl.enable=true

### 三、编写单元测试验证邮件发送 ###

1）、发送简单邮件

@Autowired
        JavaMailSenderImpl mailSender;
        @Test
        public void contextLoads() {
            SimpleMailMessage mailMessage = new SimpleMailMessage();
            //邮件设置
            mailMessage.setSubject("通知-今晚开会");
            //邮件内容
            mailMessage.setText("今晚8:30开会");
            //发给谁
            mailMessage.setTo("要发送的邮箱");
            //谁发的
            mailMessage.setFrom("自己的邮箱");
            mailSender.send(mailMessage);
        }

2）、发送带附件邮件

@Autowired
        JavaMailSenderImpl mailSender;
      @Test
        public void testMail() throws MessagingException {
            //创建一个复杂的消息邮件
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
            //主题
            helper.setSubject("明天开会");
            //内容
            helper.setText("<b style='color:red'>明天9:00开会</b>",true);
            //附件
            helper.addAttachment("1.jpg",new File("F:\\DataOfHongQuanzheng\\图片\\timg (4).jpg"));
            helper.addAttachment("2.jpg",new File("F:\\DataOfHongQuanzheng\\图片\\timg (5).jpg"));
            //发给谁
            helper.setTo("要发送的邮箱");
            //谁发的
            helper.setFrom("自己的邮箱");
            mailSender.send(mimeMessage);
        }
