java - 部署到 war 的 Spring Boot 不发送谷歌电子邮件

Question

我有一个 Spring Boot 应用程序，当我运行时，我可以成功发送电子邮件，但是当我将其部署到我的 AWS 服务器上时，它突然无法发送电子邮件并抛出错误:

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=AKgnsbsv

代码:

@Value("${spring.mail.username}")
private String recipient;

@Autowired
private JavaMailSender javaMailSender;

public SimpleStatusObject sendEmail(SimpleEmail simpleEmail) throws MessagingException, UnsupportedEncodingException {
    MimeMessage message = javaMailSender.createMimeMessage();
    MimeMessageHelper helper = new MimeMessageHelper(message);

    helper.setTo(recipient);
    helper.setFrom("MOJA_STRONA");
    helper.setReplyTo(simpleEmail.getSenderEmail(), simpleEmail.getSenderName());
    helper.setSubject(simpleEmail.getSubject());
    helper.setText(simpleEmail.getMessage());

    javaMailSender.send(message);
    return new SimpleStatusObject(Status.SUCCESS, "message sent");
}

属性

spring.mail.host = smtp.gmail.com
spring.mail.username=email@gmail.com
spring.mail.password=mypass
spring.mail.properties.mail.smtp.auth = true
spring.mail.properties.mail.smtp.socketFactory.port = 465
spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback = false

凭据没问题，我在帐户设置中启用了安全性较低的应用程序。我不知道问题出在哪里。

Answer 1

我找到了解决方案。问题不在于 Spring 。只是有时“允许访问安全性较低的应用程序”还不够。

以下是 Google 可能不允许访问的更多信息。 https://support.google.com/accounts/answer/6009563

第一个提示是:

1. 前往: https://g.co/allowaccess
2. 允许从不同设备登录。
3. 使用不同的设备登录。

这对我的案例有帮助。
