我在使用JavaMail發送帶附件的郵件時候，每次到了Transport.sendMessage()這一步，控制臺就會輸出附件內容，請問如何設置可以取消輸出呢？

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);

// 郵件正文

MimeBodyPart text? = new MimeBodyPart();

text.setContent(content, MAIL_CONTENT_FORMAT_CHARSET);
