如何设置“名称”？电子邮件中的属性 [英] How do I set the "name" attribute in an email

问题描述

我使用Java邮件和SMTP服务器发送邮件。我希望能够更改收件人在收到电子邮件时看到的名称 - 而不仅仅是电子邮件地址的前缀（@之前的位）。

I am sending mail with Java mail and an SMTP server. I want to be able to change the "name" that the recipient sees when they get an email message - not simply the prefix of the email address (the bit before @).

我怀疑我需要更改或添加'props.put（）;'设置之一，但我无法确定哪一个。

I suspect I need to change or add one of the 'props.put();' settings but I can't work out which one.

public class Email {

    private final String HOST = "mail.myserverr.com";
    private final String USER = "me+myserver.com";
    private final String FROM = "[e-mail]";
    private final String PASS = "mypass";
    private final String PORT = "25";
    private final String AUTH = "true";

    @Test
    public void sendMail(){
        String[] to = {"[e-mail]","me@myservercom"};
        sendMessage(to,"Let's go","What's up");

    }

    public void sendMessage(String[] to, String subject, String msg) {

        Properties props = System.getProperties();
            props.put("mail.smtp.starttls.enable", "true"); // added this line
            props.put("mail.smtp.host", HOST);
            props.put("mail.smtp.user", USER);
            props.put("mail.smtp.password", PASS);
            props.put("mail.smtp.port", PORT);
            props.put("mail.smtp.auth", AUTH);
            props.put("mail.smtp.socketFactory.port", PORT);
            props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            props.put("mail.smtp.socketFactory.fallback", "false");


        Session session = Session.getDefaultInstance(props, null);
        MimeMessage message = new MimeMessage(session);
        try {
            message.setFrom(new InternetAddress(FROM));

        InternetAddress[] toAddress = new InternetAddress[to.length];

        // To get the array of addresses
        for( int i=0; i < to.length; i++ ) { // changed from a while loop
            toAddress[i] = new InternetAddress(to[i]);
        }

        for( int i=0; i < toAddress.length; i++) { // changed from a while loop
            message.addRecipient(Message.RecipientType.TO, toAddress[i]);
        }

        message.setSubject(subject);
        message.setText(msg);

        Transport transport = session.getTransport("smtps");
        transport.connect(HOST, USER, PASS);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();

        } catch (AddressException e) {
            e.printStackTrace();
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

推荐答案

典型的地址语法格式为[e-mail]或个人姓名< [e-mail]> 。

您可以对FROM和TO字段地址使用相同的语法。

Typical address syntax is of the form "[e-mail]" or "Personal Name <[e-mail]>".
You can use the same syntax for both FROM and TO field addresses.

示例：

更改以下声明：

String [ ] to = {[e-mail]，me @ myservercom};

to

String [] to = {Recipient1 Name< [e-mail]>，My Name< me @ myservercom>};

您还可以构造InternetAddress对象，将相应的电子邮件ID和个人名称作为参数传递。

示例：

You can also construct InternetAddress objects passing respective e-mailID and personal names as arguments.
Example:

String FROM = "[e-mail]";  
InternetAddress from = new InternetAddress( FROM, "Ravinder" );  

收件人会看到发件人姓名显示为Ravinder而不是[e-mail]

Recipient will see sender name for display as "Ravinder" instead of "[e-mail]"

参考： javax.mail.internet .InternetAddress
