java邮件记录html模板到catalina.out

Question

我正在使用velocity 为要发送的电子邮件生成基于HTML 模板的内容，并使用Spring 的MimeMessageHelper Java Mail API 来发送电子邮件。我面临的问题是，在渲染时，HTML 模板被抛出到catalina.out，这使得文件变大，这是不可取的。

我有一个单独的应用程序日志文件，用于生成日志。有什么办法可以让我将此渲染重定向到我的应用程序日志文件？或者我可以阻止这个被扔到catalina.out。

以下是发送电子邮件时写入的详细信息

这里是日志配置

还有发送邮件的代码

JavaMailSender mailSender; // injected through Spring DI

/**
 * The mail message.
 */
SimpleMailMessage mailMessage; // Spring DI

@Override
public void sendEMail(final EmailServiceRequest request, byte[] data) {
    MimeMessage message = mailSender.createMimeMessage();
    OutputStream outStream = null;
    try {

        MimeMessageHelper helper = new MimeMessageHelper(message, true);


        // set attributes
        if (null != request.getRecipientEmailId()) {
            helper.setTo(request.getRecipientEmailId());
        }
        helper.setFrom(request.getSenderEmailId());
        helper.setSubject(request.getSubject());
        helper.setText(request.getContent(), true);

        // check for recipient list
        if (null != request.getRecipients() && !request.getRecipients().isEmpty()) {
            InternetAddress[] recipients = new InternetAddress[request.getRecipients().size()];

            for (int index = 0; index < request.getRecipients().size(); index++) {
                recipients[index] = new InternetAddress(request.getRecipients().get(index));
            }
            helper.setTo(recipients);
        }

        // data handler
        if (null != data) {
            try {

                File file = File.createTempFile(request.getAttachmentName(), "");
                outStream = new FileOutputStream(file);
                outStream.write(data);

                helper.addAttachment(request.getAttachmentName(), file);
            } catch (IOException e) {
                logger.error(e.getMessage(), e);
            } finally {
                try {
                    outStream.flush();
                    outStream.close();
                } catch (IOException e) {
                    logger.error(e.getMessage(), e);
                }
            }
        }

        if (!StringUtil.isNullOrEmpty(request.getEmailIdCC())) {
            helper.addCc(request.getEmailIdCC());
        }
        if (!StringUtil.isNullOrEmpty(request.getEmailIdBCC())) {
            helper.addBcc(request.getEmailIdBCC());
        }

        mailSender.send(message);
    } catch (MessagingException e) {
        logger.error(e.getLocalizedMessage(), e);
    }
}

Answer 1

我假设您在上下文配置中定义了一个类 org.springframework.mail.javamail.JavaMailSenderImpl 的 bean。

如果是这样，您可以尝试在会话上设置调试属性。

mailSender.getSession().setDebug(false);

或者创建一个属性文件并在那里设置设置值。

mail.debug=false
