SpringBoot实现邮件发送

导入springBoot的mail启动器

    org.springframework.boot
    spring-boot-starter-mail
    2.5.7

配置文件

spring:
  mail:
    username: 151853xxxx@qq.com  #自己的邮箱
    password: hcumnoeufqpnhfda  # 授权码代替密码
    host: smtp.qq.com 

值得注意的是，我用的是QQ邮箱，首先要开启POP3/SMTP服务 （在QQ邮箱设置中）并获取授权码。

开始测试

@SpringBootTest
class SpringBootMailApplicationTests {

    @Autowired
    private JavaMailSenderImpl javaMailSender;

    @Test
    void contextLoads() {
        //一个简单的邮件
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setSubject("simple mail message");//主题
        mailMessage.setText("简单的文本"); //正文
        mailMessage.setTo("151853xxxx@qq.com");
        mailMessage.setFrom("151853xxxx@qq.com");
        javaMailSender.send(mailMessage); //发送
    }
    @Test
    void testMail() throws MessagingException {
        //一个复杂的邮件
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        //开始组装复杂邮件
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setSubject("mime message");
        helper.setText("
 这是带颜色的
",true);
        //添加附件
        helper.addAttachment("恍恍惚惚.jpg",new File("C:\Users\admin\Pictures\Camera Roll\0EDDADFC6D8890D1F60AEFA372EAA884.jpg"));
        helper.setTo("151853xxxx@qq.com");
        helper.setFrom("151853xxxx@qq.com");
        javaMailSender.send(mimeMessage);
    }
