是否可以使用 Java 发送电子邮件,以便我可以在 to/cc/bcc 字段中看到多个收件人?
换句话说,是这样的:
From: foo@bar.com
To: user1@lol.com; user2@lol.com; user3@lol.com; user4@lol.com
Cc: admin1@lol.com; admin2@lol.com
我在谷歌上搜索,但没有找到确凿的结果,所以任何建议都将不胜感激。
是的!查看javax.mail 库。
这是一个代码示例:
class EmailSender{
private Properties properties;
private Session session;
private Message msg;
private final String SENDER_EMAIL = "your.email@whatever.com";
private final String PWD = "***********";
public void sendMail(String body) throws Throwable{
initMail();
msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("SENDER_EMAIL"));
//HERE YOU CAN CHOOSE BETWEEN TO, CC & BCC
msg.setRecipient(Message.RecipientType.TO, new InternetAddress("Receiver Email"));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress("Receiver Email2"));
msg.setRecipient(Message.RecipientType.CC, new InternetAddress("CC Email"));
msg.setRecipient(Message.RecipientType.CC, new InternetAddress("CC Email2"));
msg.setSubject("SUBJECT");
msg.setText(body);
//TRANSPORT
Transport.send(msg);
System.out.println("message sent!");
}
private void initMail(){
//PROPERTIES
//I choosed GMAIL for the demonstration, but you cant choose whatever you want.
properties = new Properties();
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.host", "smtp.gmail.com");
properties.put("mail.smtp.port", "587");
//AUTHENTICATION
session = Session.getInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(SENDER_EMAIL, PWD);
}
});
}
}
不要忘记导入javax.activation 库。
是的。
怎么做 - 取决于您使用的库。
