Question

我有以下代码，可以从gmail发送邮件。问题是我应该在哪个部分添加CC和BCC接收器，以便他们也可以接收邮件。

我做了一个搜索并在这里找到了一些帮助，但它对我的程序没有用，我在BCC和CC列表上收到错误。

    InternetAddress[] myToList = InternetAddress.parse("gopi.mani@xyz.com,Maimsa.SF@xyz.com"); 
    InternetAddress[] myBccList = InternetAddress.parse("Usha.B@xyz.com"); 
    InternetAddress[] myCcList = InternetAddress.parse("NEHA.SIVA@xyz.com"); 


    message.setRecipients(Message.RecipientType.TO,myToList); 
    message.addRecipient(Message.RecipientType.BCC,myBccList); 
    message.addRecipient(Message.RecipientType.CC,myCcList);

代码

 import javax.mail.*;
    import javax.mail.internet.*;
    import java.util.*;

    public class SendEmail {

        private static final String SMTP_HOST_NAME = "smtp.gmail.com";
        private static final int SMTP_HOST_PORT = 587;
        private static final String SMTP_AUTH_USER = "sender@gmail.com";
        private static final String SMTP_AUTH_PWD = "";

        public static void main(String[] args) throws Exception {
            SendEmail se = new SendEmail();
            se.mail();
        }

        public void mail() throws Exception {
            Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.socketFactory.port", "465");
            props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.port", "465");

            Session mailSession = Session.getDefaultInstance(props);
            mailSession.setDebug(true);
            Transport transport = mailSession.getTransport();
            MimeMessage message = new MimeMessage(mailSession);
            message.setSubject("Testing SMTP From Java");

            message.setContent("Hello world", "text/plain");

            message.addRecipient(Message.RecipientType.TO, new InternetAddress("receiver@gmail.com"));

            transport.connect(SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);
            transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
            transport.close();
        }
    }

Answer 1

变化：

message.setRecipients(Message.RecipientType.TO,myToList);

为：

message.addRecipients(Message.RecipientType.TO,myToList);

然后：

transport.sendMessage(message, message.getAllRecipients());

不是直接的答案，但这可以帮助您采取不同的方法。我是公共电子邮箱的粉丝：http://commons.apache.org/proper/commons-email/

您可以发送这样的电子邮件，这样可以更直接地阅读。

Email email = new SimpleEmail();
email.setHostName("smtp.googlemail.com");
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator("username", "password"));
email.setSSLOnConnect(true);
email.setFrom("user@gmail.com");
email.setSubject("TestMail");
email.setMsg("This is a test mail ... :-)");
email.addTo("foo@bar.com");
email.send();
