How to send mails to multiple recipients through java mail api
提问by ndsfd ddsfd
Below is the java program which send a mail through java mail api now the issue is that I want to enter multiple addresses into mailTo field. In the below code, you can see there is single entry for mailTo that is [email protected]. However, I want to pass multiple entries as [email protected], [email protected], and [email protected]. Please advise how to achieve this.
下面是通过java mail api发送邮件的java程序，现在问题是我想在mailTo字段中输入多个地址。在下面的代码中，您可以看到 mailTo 有一个条目，即 [email protected]。但是，我想以 [email protected]、[email protected] 和 [email protected] 的形式传递多个条目。请告知如何实现这一点。
public class abcMailTest {
public static void main(String[] args) {
String mailSmtpHost = "77.77.77.77";
String mailSmtpPort = "4321" ;
String mailTo = "[email protected]";
//String mailCc = "[email protected] ";
String mailFrom = "[email protected]";
String mailSubject = "sgdtetrtrr";
String mailText = "Test Mail for mail body ";
sendEmail(mailTo, mailFrom, mailSubject, mailText, mailSmtpHost ,mailSmtpPort );
}
public static void sendEmail(String to, String from, String subject, String text, String smtpHost , String mailSmtpPort) {
try {
Properties properties = new Properties();
properties.put("mail.smtp.host", smtpHost);
properties.put("mailSmtpPort", mailSmtpPort);
//obtaining the session
Session emailSession = Session.getDefaultInstance(properties);
emailSession.setDebug(true);
//creating the message
Message emailMessage = new MimeMessage(emailSession);
emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
Address[] cc = new Address[] {
new InternetAddress("[email protected]"),
new InternetAddress("[email protected]")};
emailMessage.addRecipients(Message.RecipientType.CC, cc);
emailMessage.setFrom(new InternetAddress(from));
emailMessage.setSubject(subject);
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(text, "text/html");
messageBodyPart.setText(text);
// Create a multipart message
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
MimeBodyPart attachPart = new MimeBodyPart();
String filename = "c:\abc.pdf";
DataSource source = new FileDataSource(filename);
attachPart.setDataHandler(new DataHandler(source));
attachPart.setFileName(filename);
multipart.addBodyPart(attachPart);
// Send the complete message parts
emailMessage.setContent(multipart);
emailSession.setDebug(true);
Transport.send(emailMessage);
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
}
}

You just need to do the same thing as what you did for cc field
你只需要做与你对 cc 字段所做的相同的事情
Address[] to = new Address[] {InternetAddress.parse("[email protected]"),
InternetAddress.parse("[email protected]"),
InternetAddress.parse("[email protected]")};
message.addRecipients(Message.RecipientType.TO, to);

Try this
试试这个
String cc = "[email protected];[email protected]";
StringTokenizer st = new StringTokenizer(cc,":");
while(st.hasMoreTokens()) {
emailMessage.addRecipients(Message.RecipientType.CC, InternetAddress.parse(st.nextToken(),false);
}
