JavaMailSender：身份验证失败

Question

我无法为. 之类的电子邮件发送邮件，例如example.ca@gmail.com，但是example@gmail.com 之类的电子邮件是成功的。

我使用 spring helper 和 smtp.gmail.com 设置发送邮件。

        // Prepare message using a Spring helper
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        try {
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage, isMultipart, StandardCharsets.UTF_8.name());
            message.setTo(to);
            message.setFrom(jHipsterProperties.getMail().getFrom());
            message.setSubject(subject);
            message.setText(content, isHtml);
            javaMailSender.send(mimeMessage);
            log.debug("Sent email to User '{}'", to);
        } catch (MailException | MessagingException e) {
            log.warn("Email could not be sent to user '{}'", to, e);
        }

它清楚地表明您的凭据有问题。首先尝试验证相同的凭据是否在浏览器中有效。

org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is javax.mail.AuthenticationFailedException: 534-5.7.14 <https://accounts.google.com/signin/continue?sarp=1&scc=1&plt=AKgnsbv
534-5.7.14 Please log in via your web browser and then try again.
