java – 如何在电子邮件中设置“name”属性
我发送邮件与 Java
邮件和SMTP服务器.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).
我怀疑我需要更改或添加’props.put();’设置,但我无法解决哪一个.
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();
}
}
}
典型的地址语法格式为“user@host.domain”或“Personal Name<user@host.domain/u0026gt;”.
您可以对FROM和TO字段地址使用相同的语法.
例：
更改以下声明：
String [] to = {“mygmail@gmail.com”,“me @ myservercom”};
至
String [] to = {“Recipient1 Name<mygmail@gmail.com/u0026gt;”,“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.
例：
String FROM = "my.email.id@my.server.domain"; InternetAddress from = new InternetAddress( FROM, "Ravinder" );
收件人将看到发件人姓名显示为“Ravinder”而不是“my.email.id@my.server.domain”
