Spring integration 如何在Spring集成邮件支持中轮询多封电子邮件

我需要轮询邮件服务器。由于我的项目已经在Spring中，我使用Spring集成来轮询邮件服务器。我在这方面很成功。但现在我不得不调查多封电子邮件。有人能告诉我怎么做吗

这是我用来轮询单个邮件的示例代码

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

<mail:inbound-channel-adapter id="imapAdapter"
                                      store-uri="${imap.uri}"                                    
                                      channel="recieveEmailChannel"                                         
                                      should-delete-messages="false"
                                      should-mark-messages-as-read="true"                                     
                                      auto-startup="true"
                                      java-mail-properties="javaMailProperties">
        <int:poller fixed-delay="${imap.poolerSecondsDelay}" time-unit="SECONDS"/>
    </mail:inbound-channel-adapter>

    <int:channel id="recieveEmailChannel">        
        <int:interceptors>
            <int:wire-tap channel="logger"/>
        </int:interceptors>
    </int:channel>

    <int:logging-channel-adapter id="logger" level="DEBUG"/>

    <int:service-activator input-channel="recieveEmailChannel" ref="emailReceiverService" method="receive"/>

    <bean id="emailReceiverService" class="com.usbank.hermes.serviceimpl.EmailReceiverService">
    </bean>

javax.net.ssl.SSLSocketFactory
假的
imaps
假的

将“每次轮询的最大消息数”添加到轮询器中

即：

每次轮询时，它将从队列中获取10封邮件

<int:poller max-messages-per-poll="10" fixed-delay="${imap.poolerSecondsDelay}" time-unit="SECONDS"/>
