我不知道爲什麼它是發生在另外我啓用IMAP選項在我的Gmail帳戶設置。

Ihis是我的代碼：

Properties protocol = new Properties(); 
protocol.setProperty("mail.store.protocol", "imaps"); 

try{ 
     Session session = Session.getInstance(protocol, null); 
     Store store = session.getStore(); 
     String host = prop.getProperty("host"); 
     String email = prop.getProperty("username"); 
     String password = prop.getProperty("password"); 
     store.connect(host, email, password); 
     Folder inbox = store.getFolder("INBOX"); 
     inbox.open(Folder.READ_ONLY); 
     int messageCount = inbox.getMessageCount(); 
     model.addAttribute("msg","number of mails"+" "+messageCount); 
     Message[] messages = inbox.getMessages(); 
     PrintWriter writer = new PrintWriter(username+".txt", "UTF-8"); 

     for(int i=0;i<messageCount || prop.getProperty("status").equals(status.RUNNING.toString()) ;i++){ 
      model.addAttribute("msg","Reading Mails"); 
      Multipart mp = (Multipart) messages[i].getContent(); 
      BodyPart bp = mp.getBodyPart(0); 
      writer.println("From:"+ messages[i].getFrom()+" "+"Subject:"+messages[i].getSubject()+" "+"Message:"+bp.getContent()); 
      prop = loadProperties(username+".properties"); 
     } 
     writer.close(); 
     inbox.close(true); 
     store.close(); 

    }catch (Exception e){ 
        model.addAttribute("msg","Exception:"+e.getMessage()); 
}

您是否在您的Gmail帳戶中激活了「IMAP」協議？它不是默認打開的，您需要深入瞭解設置並啓用它https://support.google.com/mail/troubleshooter/1668960?hl=zh-CN –

yes是，imap已啓用，如上所述。 –

gmail的主機應該是imap.gmail.com嗎？ –
