我正在使用javaMailSender发送邮件。
Java邮件生产者：
// Publishing the message to the JMS queue.
queueClinicalMessageServiceTemplate.send(new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
MapMessage mapMessage = session.createMapMessage();
mapMessage.setStringProperty(ActivemqConstants.KEY_EMAIL_ADDRESS, email);
mapMessage.setStringProperty(ActivemqConstants.KEY_PASSWORD, password);
mapMessage.setStringProperty(ActivemqConstants.KEY_REG_MSG_TYPE,
ActivemqConstants.VALUE_SEND_CLI_REG_EMAIL);
return mapMessage;
}
});
Java邮件使用者：
try {
logger.debug("JMSMessageID = {}; MSDeliveryMode = {}; JMSRedelivered = {}; JMSQueue = {}.",
msg.getJMSMessageID(), msg.getJMSDeliveryMode(), msg.getJMSRedelivered(),
msg.getStringProperty(ActivemqConstants.KEY_REG_MSG_TYPE));
if (msg instanceof MapMessage) {
MapMessage mapMsg = (MapMessage) msg;
String email = mapMsg.getStringProperty(ActivemqConstants.KEY_EMAIL_ADDRESS);
String password = mapMsg.getStringProperty(ActivemqConstants.KEY_PASSWORD);
Map<String, String> model = new HashMap<String, String>();
model.put("password", password);
emailSender.sendMail(messageSource.getMessage("mail.username", null, null, null), email,
"Subject", model,
"com/utils/RegistrationEmail.ftl");
}
} catch (JMSException ex) {
logger.error("JMSException:", ex);
throw new RuntimeException(ex);
}
public void sendMail(final String from, final String to, final String subject, final Object model,
final String template) throws MailException {
MimeMessagePreparator mimeMessagePreparator = new MimeMessagePreparator() {
public void prepare(MimeMessage mimeMessage) throws Exception {
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
mimeMessageHelper.setFrom(from);
mimeMessageHelper.setTo(to);
mimeMessageHelper.setSubject(subject);
String text = FreeMarkerTemplateUtils
.processTemplateIntoString(freemarkerConfiguration.getTemplate(template, "UTF-8"), model);
// boolean true is for html
mimeMessageHelper.setText(text, true);
}
};
try {
logger.info("Attempting to send email via Gmail now");
javaMailSender.send(mimeMessagePreparator);
} catch (Exception e) {
logger.debug("MailException occured while sending the mail for ftl model:::{}::: MailException object::{}",
model, e);
try {
logger.info("Attempting to send email via Gmail now");
alternateJavaMailSender.send(mimeMessagePreparator);
} catch (MailException ae) {
logger.error(
"MailException occured while sending the mail for ftl model:::{}::: MailException object::{}",
model, ae);
throw ae;
}
}
}
邮件配置
mail.username=XXX@gmail.com
mail.password=YYY
mail.host=smtp.gmail.com
mail.smtp.port=25
mail.smtp.auth=true
当我在本地系统上运行相同的代码时，我能够成功发送所有邮件（一次发送20到30）。但是在生产（AWS）服务器上，从20到30封邮件中仅接收3到4封邮件。并在生产服务器上获取以下异常：
10:51:15.667 [userRegEmailDMLC-1] DEBUG [net.abc.xyz.consumer.utils.EmailSender]-MailException occured while sending the mail for ftl model:::{password=AppleGoldDiamond}::: MailExce

可能是问题所在，因为我在生产上遇到了错误，但在本地遇到了错误。

由于安全原因，默认情况下，EC2在发送邮件方面有严格的限制。您必须发送支持请求（以root用户身份登录帐户，然后按照link进行操作），这是确保邮件流合法的责任。
尽管如此，建议您use SES instead 。
