Question

我在我的项目中使用spring集成。以下是我的应用程序中的流程。我什么时候发布消息给＆＃34; domainEventChannel＆＃34; ，它通过变压器，然后消息被发送到 inputFromTransformer 通道，并由此消息在链中它通过分离器，变换器和过滤器。我已经配置了 output-channel =＆＃34; domainEventQueueChannel＆＃34; ，这是一个队列频道。

我能够跟踪消息直到过滤器，但它们永远不会到达QueueChannel。

我是否可以从链中向队列通道发送消息？

<int:transformer ref="partitionlessTransformer" method="transform"
        input-channel="domainEventChannel" output-channel="inputFromTransformer" />

   <!-- Chain which has the output channel as queue channel-->
    <int:chain input-channel="inputFromTransformer"
        output-channel="domainEventQueueChannel">
        <int:splitter ref="messageSplitter" method="split" />
        <int:transformer ref="jsonToObjectTransformer" />
        <int:filter ref="autopayModelProcessTransFilter"></int:filter>
    </int:chain>

   <!-- Queue Channel-->
    <int:channel id="domainEventQueueChannel">
        <int:queue capacity="10" />
    </int:channel>

     <!-- service activator which polls queueChannel -->
    <int:service-activator id="domainEventReconProcessServiceActivator"
         input-channel="domainEventQueueChannel" ref="domainEventReconProcessServiceActivator" method="intiateAutopayProcessTransRecon">
        <int:poller task-executor="domainEventReconProcessServicetaskExecutor" fixed-rate="10" >
            </int:poller>
    </int:service-activator>

    <task:executor id="domainEventReconProcessServicetaskExecutor"
        pool-size="10" queue-capacity="10" />

更新2＃： 当我添加以下配置时，一切正常。消息从队列通道流向服务激活器：

    <int:chain input-channel="domainEventQueueChannel"
        output-channel="nullChannel">
        <int:service-activator id="domainEventReconProcessServiceActivator"
         ref="domainEventReconProcessServiceActivator" method="intiateAutopayProcessTransRecon" />
     <int:poller task-executor="domainEventReconProcessServicetaskExecutor"  fixed-rate="10"></int:poller> 
 </int:chain>

更新3＃： 随着链的到位，我看到服务激活器的轮询器轮询queueChannel。但是没有链条，轮询器根本就没有开始我根本看不到轮询器日志。

随着链条到位：

Answer 1

这只是意味着消息没有通过过滤器。

（过滤器正在删除该消息）。

在Spring集成
