E-Mail kann nicht mit IMAP in JAVA gelesen werden.

Question

Ich versuche, E-Mail von Mail Server mit JAVA zu lesen. Ich habe das IMAP-Protokoll dafür verwendet.

Jedes Mal, wenn ich Anfrage zum Lesen einer E-Mail senden, wirft es mich Ausnahme: javax.mail.MessagingException: Unerkannte SSL-Nachricht, Klartextverbindung?

Hier ist mein Code;

public void readEmail() throws Exception { 
    sessionIMAP = setupImap(); 
    Store store = sessionIMAP.getStore("imap"); 
    store.connect("localhost", 1143, "username", "password"); 
    if (store.isConnected()) { 
     System.out.println("IMAP is connected"); 
    } else { 
     System.out.println("IMAP is not connected"); 
    } 

} 

private Session setupImap() { 
    System.out.println("in setupImap"); 
    Session session1; 
    Properties props = new Properties(); 
    props.put("mail.imap.starttls.enable", "true"); 
    //props.put("mail.imaps.ssl.enable", "true"); 
    //props.put("mail.imaps.auth", "true"); 
    //props.put("mail.imaps.ssl.trust", "*"); 
    props.put("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
    props.put("mail.imap.socketFactory.fallback", "false"); 
    props.put("mail.imap.host", "localhost"); 
    props.put("mail.imap.port", 1143); 
    props.put("mail.imap.socketFactory.port", 1143); 
    props.setProperty("mail.store.protocol", "imap"); 
    props.put("mail.debug", "true"); 
    //props.put("mail.imaps.class", "com.sun.mail.imap.IMAPSSLStore"); 
    session1 = Session.getInstance(props, null); 
    //setupIMAPMsgTypeSetupForReportedIssue(); 
    return session1; 
} 

Hier ist die vollständige Ausnahme erhalte ich:

Könnten Sie bitte lassen Sie mich wissen, was ich falsch mache?

Vielen Dank im Voraus

Answer 1

kommentierte ich aus dem Code unter der Linie und es funktionierte!

props.put("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 

Danke
