如何在電子郵件中設置「名稱」屬性

Question

我使用Java郵件和SMTP服務器發送郵件。我希望能夠更改收件人收到電子郵件時看到的「姓名」 - 而不僅僅是電子郵件地址的前綴（@之前的位）。

我懷疑我需要更改或添加一個'props.put（）;'設置，但我不能確定哪一個。

public class Email { 

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

    @Test 
    public void sendMail(){ 
     String[] to = {"mygmail@gmail.com","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(); 
     } 
    } 
} 

Answer 1

你需要改變：

message.setFrom(new InternetAddress(FROM)); 

到

message.setFrom(new InternetAddress(FROM, "Company XYZ")); 

文檔：Class InternetAddress

網際地址

public InternetAddress(String address, 
        String personal) 
        throws UnsupportedEncodingException 

在給出的地址和個人名稱的網際地址。地址是 被假定爲語法上有效的RFC822地址。

參數：

地址 - 在RFC822格式

個人地址 - 個人名下

拋出：UnsupportedEncodingException

Answer 2

典型的地址語法形式"user@host.domain"或"Personal Name <user@host.domain>"的。
您可以對FROM和TO字段地址使用相同的語法。

例：
更改如下聲明：
String[] to = {"mygmail@gmail.com","me@myservercom"};
到
String[] to = {"Recipient1 Name <mygmail@gmail.com>","My Name <me@myservercom>"};

您也可以通過構建相應的電子mailID和個人名作爲參數網際地址對象。
例：

String FROM = "my.email.id@my.server.domain"; 
InternetAddress from = new InternetAddress(FROM, "Ravinder"); 

收件人將看到發送者姓名以顯示爲"Ravinder"代替"my.email.id@my.server.domain"

參考：javax.mail.internet.InternetAddress
