从InternetAddress打印出发件人的电子邮件地址

Question

这是获取电子邮件sender和subject电子邮件的代码.使用此代码,我看到正确的主题显示,但我看到不同格式的发件人的地址.

Properties props = new Properties();
    props.put("mail.imap.host" , "imap.gmail.com" );
    props.put("mail.imap.user" , "username");
    // User SSL
    props.put("mail.imap.socketFactory" , 993);
    props.put("mail.imap.socketFactory.class" , "javax.net.ssl.SSLSocketFactory" );
    props.put("mail.imap.port" , 993 );
    Session session = Session.getDefaultInstance(props , new Authenticator() {
        @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication("username" , "password");
        }
    });

    try {
      Store store = session.getStore("imap");
      store.connect("imap.gmail.com" , "username" , "password");
      Folder fldr = store.getFolder("Inbox");
      fldr.open(Folder.READ_ONLY);
      Message msgs[] = fldr.getMessages();
        for(int i = 0 ; i < msgs.length ; i++) {
            System.out.println(msgs[i].getFrom() + "<-- FROM" + " " + msgs[i].getSubject() + "<---Subject");
        }
    } catch(Exception exc) {

    }
}

输出是:

[Ljavax.mail.internet.InternetAddress;@1462851<-- FROMGet Gmail on your mobile phone<---Subject
[Ljavax.mail.internet.InternetAddress;@bdab91<-- FROMImport your contacts and old email<---Subject
[Ljavax.mail.internet.InternetAddress;@4ac00c<-- FROMCustomize Gmail with colors and themes<---Subject
[Ljavax.mail.internet.InternetAddress;@1865b28<-- FROMtester<---Subject

它是什么形式的？(@ 1462851) 我想要发送者的电子邮件地址而不是.@1462851我怎么能这样做？

该getForm()返回的对象.要将其打印为普通字符串,请尝试InternetAddress.toString(msgs[i].getFrom())使用System.out.
