Spring Boot Starter Mail使用

• 导入jar包

• 邮箱参数配置

  #Spring Boot Starter Mail
  spring.mail.host=smtp.qq.com
  spring.mail.port=465
  spring.mail.username=邮箱
  spring.mail.password=授权码
  spring.mail.protocol=smtps
  spring.mail.properties.mail.smtp.ssl.enable=true

• 使用JavaMailSender发送邮件

  private static final Logger logger = LoggerFactory.getLogger(MailClient.class);
  
  @Autowired
  private JavaMailSender mailSender;
  
  @Value("${spring.mail.username}")
  private String from;
  
  public void sendMail(String to, String subject, String content) {
      try {
          MimeMessage message = mailSender.createMimeMessage();
          MimeMessageHelper helper = new MimeMessageHelper(message);
          helper.setFrom(from);
          helper.setTo(to);
          helper.setSubject(subject);
          helper.setText(content, true);
          mailSender.send(helper.getMimeMessage());
      } catch (MessagingException e) {
          logger.error("发送邮件失败：" + e.getMessage());
      }
  }

使用Thymeleaf发送HTML文件

@Autowired
private MailClient mailClient;

@Autowired
private TemplateEngine templateEngine;

@Test
public void testHtmlMail() {
    Context context = new Context();
    context.setVariable("username", "sunday");

    String content = templateEngine.process("/mail/activation", context);
    mailClient.sendMail("abc@qq.com", "测试邮件", content);
}
