使用javamail发送邮件的时候如何阻止附件内容输出到控制台

问题描述

问 题

我在使用JavaMail发送带附件的邮件时候，每次到了Transport.sendMessage()这一步，控制台就会输出附件内容，请问如何设置可以取消输出呢？

public void sendFileAttachedMail(String fromMail, String toMail, String fromMailPwd, String bookId) {
        Properties prop = new Properties();
        prop.setProperty(MAIL_HOST, MAIL_HOST_VALUE);
        prop.setProperty(MAIL_TRANSPORT_PROTOCOL, MAIL_TRANSPORT_PROTOCOL_VALUE);
        prop.setProperty(MAIL_SMTP_AUTH, MAIL_SMTP_AUTH_VALUE);
        Session session = Session.getInstance(prop);
        session.setDebug(true);
        try {
            Transport ts = session.getTransport();
            String fromMailPrefix = fromMail.split("@")[0];
            ts.connect(MAIL_HOST_VALUE,fromMailPrefix, fromMailPwd);
            String subject = "FILE ATTACHED MAIL TEST";
            String content = "Mail Content RE";
            String fileSavePath = "E://attachMail.eml";
            Message message = createFileAttachedMail(session, fromMail, toMail, subject, content, bookId, fileSavePath);
            ts.sendMessage(message, message.getAllRecipients());
            ts.close();
        } catch (Exception e) {
            if(logger.isErrorEnabled()){
                logger.error("send fileAttachedMail failed!",e);
            }
        }
    }
    
    
     public MimeMessage createFileAttachedMail(Session session, String fromAdd, String toAdd, String subject, String content, String fileObjectId, String fileSavePath) throws Exception {
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(fromAdd));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(toAdd));
        message.setSubject(subject);
        // 邮件正文
        MimeBodyPart text  = new MimeBodyPart();
        text.setContent(content, MAIL_CONTENT_FORMAT_CHARSET);

        // 附件
        MimeBodyPart attach = new MimeBodyPart();
        DataHandler handler = new DataHandler(new FileDataSource(this.gridFSService.readFiles(fileObjectId)));
        attach.setDataHandler(handler);
        attach.setFileName(handler.getName());

        // 创建容器描述数据关系
        MimeMultipart mp = new MimeMultipart();
        mp.addBodyPart(text);
        mp.addBodyPart(attach);
        mp.setSubType("mixed");

        message.setContent(mp);
        message.saveChanges();
        //将创建的email写入到本地存储
        //message.writeTo(new FileOutputStream(fileSavePath));
        return message;
    }

解决方案

session.setDebug(true);这句去掉
