为什么此Java邮件以纯文本而不是html的形式到达收件人? [英] Why does this java mail arrive as plain text instead of html at recipient?
问题描述
我有此代码可以发送电子邮件:
I have this code to send an email:
public static void sendHtmlTextWithPlainTextAlternative(final String to,
final String from, final String subject, final String plainText,
final String htmlText) throws MessagingException {
final HtmlEmail email = new HtmlEmail();
email.setHostName(SMTP);
try {
email.addTo(getStringAddresses(to));
email.setFrom(from);
email.setSubject(subject);
email.setHtmlMsg("<html><head></head><body><p>Hello World!</p></body></html>");
email.setTextMsg("Hello World!");
email.send();
} catch (final EmailException e) {
e.printStackTrace();
}
}
private static String[] getStringAddresses(final String to) {
return to.split(" |,|;|\\r?\\n|\\r");
}
但是我在电子邮件客户端(Outlook 2010)中得到的只是一条纯文本消息，在这里我可以看到html标记和替代的纯文本或空白的富文本消息(Outlook 2002).
But all i get in my email client (Outlook 2010) is a plain text message where I can see the html markup and the alternative plain text or a rich text message that is blank (Outlook 2002).

根据一位Exchange Server管理员的消息，邮件开头应包含以下内容
According to one Exchange Server admin the message should contain something like this at the beginning
0 2.1.5 Recipient OK
DATA
354 Start mail input; end with <CRLF>.<CRLF>
Content-Type: multipart/mixed; boundary="----=_Part_1_933059347.1364987366297"
但是它是这样到达的(摘录):
But it arrives like this (excerpt):
250 2.1.5 Recipient OK
DATA
354 Start mail input; end with <CRLF>.<CRLF>
This is the content preamble.
------=_Part_1_933059347.1364987366297
Content-Type: multipart/alternative; boundary="----=_Part_0_1905186593.1364987366295"
电子邮件到达时主题为空，收件人列表为空. 是什么原因导致这种奇怪的行为?
The email arrives with an empty subject and an empty recipient list. What could cause this strange behavior?
推荐答案
找出解决方案后很简单，我要感谢Cedric Champeau.这是与通过另一个Maven依赖项引入的geronimo-javamail发生冲突的.我要做的就是排除这种依赖性: Apache CXF + Maven + Javamail + Log4J(更新)
After finding out what to look for the solution was quite simple and I have to thank Cedric Champeau. It was a conflict with geronimo-javamail that was pulled in through another maven dependency. All I had to do was to exclude that dependency: Apache CXF + Maven + Javamail + Log4J (update)
