Question

我希望使用此示例作为构建某种“邮件处理器”的指南，其中包括：

列表项
从IMAP阅读
保存附件
在数据库中保留发件人信息和附件路径
将确认电子邮件发回给发件人

我已经构建了bean来读取mbox并像Gunnar Hillert intermediate email samples一样保存附件：

    (...)
    <int:channel id="sendChannel" />

    <int-mail:outbound-channel-adapter
        channel="sendChannel" host="${smtp.host}" username="${imap.username}"
        password="${imap.password}" />

    <int:channel id="receiveChannel" />

    <!-- replace 'userid and 'password' wit the real values -->
    <int-mail:imap-idle-channel-adapter
        id="customAdapter"
        store-uri="imap://${imap.username}:${imap.password}@${imap.host}:${imap.port}/inbox"
        channel="receiveChannel" auto-startup="true" should-delete-messages="false"
        should-mark-messages-as-read="false" java-mail-properties="javaMailProperties" />

    <util:properties id="javaMailProperties">
        <prop key="mail.imap.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
        <prop key="mail.imap.socketFactory.fallback">true</prop>
        <prop key="mail.store.protocol">imap</prop>
        <prop key="mail.debug">${mail.debug}</prop>
    </util:properties>

    <int:chain id="transform-split" input-channel="receiveChannel"
        output-channel="outputChannel">
        <int:transformer>
            <bean class="it.lrkwz.imap.support.EmailTransformer" />
        </int:transformer>
        <int:splitter>
            <bean class="it.lrkwz.imap.support.EmailSplitter" />
        </int:splitter>
    </int:chain>

    <int:channel id="outputChannel" />

    <int-file:outbound-channel-adapter
        id="save-as-file" auto-create-directory="true" channel="outputChannel"
        directory-expression="'target/out/' + headers.directory" />
</beans>

在哪里（main（），EmailTransformer（），EmailSplitter（），...）我应该拦截“无附件”状态？如何向发件人发送电子邮件？

@SpringBootApplication
@ImportResource("classpath:META-INF/spring/integration/aruba-imap-idle-config.xml")
public class ImapProcessorApplication implements CommandLineRunner {
    private static Logger logger = LoggerFactory.getLogger(ImapProcessorApplication.class);

    public static void main(String[] args) {
        ConfigurableApplicationContext applicationContext = SpringApplication.run(ImapProcessorApplication.class, args);
    }

    @Autowired
    DirectChannel receiveChannel;

    @Autowired
    DirectChannel sendChannel;

    @Override
    public void run(String... arg0) throws Exception {
        receiveChannel.subscribe(new MessageHandler() {
            public void handleMessage(Message<?> message) throws MessagingException{
    ...

谢谢。

要处理“无附件”状态，您应该遵循标准的Spring Integration配方并将<filter>添加到您的流程中。看起来就在你的<splitter>之后（如果你用`Multipart分割你的信息）。在这里，您可以找到BTW，如何拆分和过滤：Download attachments using Java Mail。

您已经<int-mail:outbound-channel-adapter>发送电子邮件。那么，您需要的是outputChannel为<publish-subscriber-channel>并添加更多订阅者（<outbound-channel-adapter>，<service-activator>，<outbound-gateway>等）并发送确认电子邮件，将数据存储到DB。任何你想要和需要的东西！
