@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);
