使用 javax 邮件发送的电子邮件发送时主题和字段为空
Email sent using javax mail delivers with empty subject and to fields
我正在使用以下代码从我的应用程序发送电子邮件：
MimeMessage message = new MimeMessage(session);
String encodingOptions = "text/html; charset=UTF-8";
message.setHeader("Content-Type", encodingOptions);
message.setFrom(new InternetAddress(fromEmailAddress));
String[] toAddressArr = emailMsg.getTo().split(CommonConstants.SEMI_COLON);
for (String srtAddress : toAddressArr) {
InternetAddress ia = new InternetAddress(srtAddress);
addressToList.add(ia);
}
InternetAddress[] addressTo = new InternetAddress[addressToList.size()];
message.setRecipients(MimeMessage.RecipientType.TO, addressToList.toArray(addressTo));
if (!Util.isNullOrBlank(emailMsg.getCc())) {
String[] copyAddressArr = emailMsg.getCc().split(CommonConstants.SEMI_COLON);
ArrayList<InternetAddress> addressCopyList = new ArrayList<>();
for (String srtAddress : copyAddressArr) {
InternetAddress ia = new InternetAddress(srtAddress);
addressCopyList.add(ia);
}
InternetAddress[] addressCopy = new InternetAddress[addressCopyList.size()];
message.setRecipients(MimeMessage.RecipientType.CC, addressCopyList.toArray(addressCopy));
}
if (!Util.isNullOrBlank(emailMsg.getBcc())) {
String[] bccAddressArr = emailMsg.getBcc().split(CommonConstants.SEMI_COLON);
ArrayList<InternetAddress> addressBccList = new ArrayList<>();
for (String srtAddress : bccAddressArr) {
InternetAddress ia = new InternetAddress(srtAddress);
addressBccList.add(ia);
}
InternetAddress[] addressBcc = new InternetAddress[addressBccList.size()];
message.setRecipients(MimeMessage.RecipientType.BCC, addressBccList.toArray(addressBcc));
}
message.setSubject(emailMsg.getSubject(), "UTF-8");
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(emailMsg.getMessage());
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
}
}
使用上面的代码，我将电子邮件发送到收件人的电子邮件地址，但是，主题字段为空，收件人字段也为空，而所有收件人都显示在电子邮件的密件抄送字段中。此外，附件以字节字符串形式出现，而不是可下载的 pdf 文件。
以下是其中的示例：
user@gmail.com to bcc: user@outlook.com, bcc: user@domain.com

我的意图是发送具有 html 格式的电子邮件，但是，我无法继续 objective，因为我被这个节目阻止者阻止了。
任何帮助将不胜感激。

我附上了一个 pdf 文件，将作为电子邮件附件发送，代码如下：
if (attachments != null) {
for (EmailAttachmentData attachment : attachments) {
MimeBodyPart attachPart = new MimeBodyPart();
DataSource source = new ByteArrayDataSource(attachment.getData(),
attachment.getFileType());
attachPart.setDataHandler(new DataHandler(source));
attachPart.setFileName(attachment.getFileName());
multipart.addBodyPart(attachPart);
}
}
message.setContent(multipart);
message.setSentDate(new Date());
try {
Transport transport = session.getTransport(mailProtocol);
transport.connect(mailHost, Integer.parseInt(mailPort), userName, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (Exception ex) {
ex.printStackTrace();
}
这是我对 javax mail 的 maven 依赖定义
<dependency>
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
<scope>provided</scope>
</dependency>
您使用的是哪个版本的 JavaMail？
您的收件人代码看起来不错，尽管比必要的要冗长得多。
但是你的内容代码全错了。
带有附件的邮件是包含多部分内容的邮件，其中一个正文部分包含主要邮件内容，另一个正文部分包含附件。
您的代码并未显示您实际发送消息的方式。
你刚刚打电话给 Transport.send 吗？
我终于通过从我的一些 Maven 依赖项中排除 geronimo-javamail_1.4_spec 和 geronimo-activation_1.1_spec 解决了我自己的问题。我也有多个 javax.mail-api 和 javax.mail 依赖项，因此删除重复项挽救了这一天。现在一切正常。主题和收件人字段填充良好，附件也已正确发送。为了清楚起见，我 post 我在下面做出的排除：
