<int:channel id="receiveChannel" />
    <int-mail:imap-idle-channel-adapter id="customAdapter" 
            store-uri="imaps://rupak@domain.com:pass@domain.com:993/INBOX.Sent"
            channel="receiveChannel"

   public static void main (String[] args) throws Exception {

            ApplicationContext ac = new ClassPathXmlApplicationContext("spring/gmail-imap-idle-config.xml");
            DirectChannel inputChannel = ac.getBean("receiveChannel", DirectChannel.class);
            inputChannel.subscribe(new MessageHandler() {
                public void handleMessage(Message<?> message) throws MessagingException {

                    MimeMessage mimeMessage = (MimeMessage) message.getPayload();



    }
});
}

参见 the documentation ，您需要使用自定义 SearchTermStrategy。

By default, the ImapMailReceiver will search for Messages based on the default SearchTerm which is All mails that are RECENT (if supported), that are NOT ANSWERED, that are NOT DELETED, that are NOT SEEN and have not been processed by this mail receiver (enabled by the use of the custom USER flag or simply NOT FLAGGED if not supported). The custom user flag is spring-integration-mail-adapter but can be configured. Since version 2.2, the SearchTerm used by the ImapMailReceiver is fully configurable via the SearchTermStrategy which you can inject via the search-term-strategy attribute. SearchTermStrategy is a simple strategy interface with a single method that allows you to create an instance of the SearchTerm that will be used by the ImapMailReceiver.
