为什么这个 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
我有发送电子邮件的代码:
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");
}
但我在电子邮件客户端 (Outlook 2010) 中得到的只是一条纯文本消息，我可以在其中看到 html 标记和替代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 管理员的说法，该消息的开头应包含类似内容
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.

收到的电子邮件主题为空，收件人列表也为空.什么可能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
在找到解决方案后，我要感谢 Cedric Champeau.这是与通过另一个 maven 依赖项引入的 geronimo-javamail 的冲突.我所要做的就是排除该依赖项: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)
