尝试通过IMAP连接连接到gmail，抓住 javax.mail.MessagingException

public static StringBuffer getEmailByBody(String username, String password, String containsMsg) throws Exception {
    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imaps");
    props.setProperty("mail.imap.ssl.enable", "true");

    Session session = Session.getDefaultInstance(props, null);
    Store store = session.getStore("imaps");
    try {
        store.connect("imap.gmail.com", username , password);
    } catch (Exception ex) {
        ex.printStackTrace();
        throw new Exception("Fail in connection" + ex.getMessage());
    }

    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_WRITE);

    Message[] messages = null;
    boolean isMailFound = false;
    Message confirmationMAil = null;

    // Search for mail MAX 10 runs
    for (int i = 0; i < 10; i++) {
        messages = folder.search(new BodyTerm(containsMsg), folder.getMessages());
        for(Message message : messages){
            if (!message.isSet(Flags.Flag.SEEN)) {
                confirmationMAil = message;
                isMailFound = true;
                break;
            }
        }
        // wait for 3 seconds if message is not found
        if (!isMailFound) {
            Thread.sleep(3000);
        }
    }

    // Search latests for unread mail
    for(Message message : messages){
        if (!message.isSet(Flags.Flag.SEEN)) {
            confirmationMAil = message;
            isMailFound = true;
            break;
        }
    }

    // Test fails if no unread mail was found from God
    if (!isMailFound) {
        throw new Exception("Could not find email");

        // Read the content of mail and launch registration URL
    } else {
        String line;
        StringBuffer buffer = new StringBuffer();
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                confirmationMAil.getInputStream()));
        while ((line = reader.readLine()) != null) {
            buffer.append(line);
        }
        return buffer;
    }
}
