在 receiveChannel 收到消息后，我想调用一个服务来做一些额外的工作。消息流将是：

JMS Message -> receiveChannel -- message-driven-adapter --> jmsInChannel -> queueChannel (here the service should be invoked)

我想通过 1) 在 queueChannel 2) 上调用的服务或使用消息适配器来实现这一点。

在后一种情况下，我不知道如何在 Spring Integration 中将服务分配给消息驱动适配器？也没有调用服务。

此配置包含两种方法，但它们都不起作用：

<int-jms:channel id="receiveChannel" 
    queue-name="FORWARD"
    connection-factory="connectionFactory" 
    auto-startup="true">
</int-jms:channel>

<si:channel id="jmsInChannel"/>
<int-jms:message-driven-channel-adapter id="messageDrivenAdapter"
    channel="receiveChannel" destination-name="jmsInChannel"/>
<si:bridge input-channel="jmsInChannel" output-channel="queueChannel"/> 

<si:channel id="queueChannel">
    <si:queue/>
</si:channel>


 <si:service-activator id ="activator" ref="messageService" 
    method="processMessage" 
    input-channel="queueChannel">
</si:service-activator>

这是我将消息发送到 FORWARD 队列的发件人：

 <si:channel id="sendChannel"/>
<int-jms:outbound-channel-adapter 
connection-factory="connectionFactory" 
destination-name="FORWARD" 
channel="sendChannel"/>

<si:gateway id="forwardGateway" 
    service-interface="com.ucware.ucpo.forward.jms.MessageGateway" 
    default-request-channel="sendChannel"/>

消息来自 ActiveMQ 后端的 FORWARD 队列。

更新：我添加了一个监听器，现在收到了消息。这是开启了 TRACE 的日志文件：

<int-jms:channel/>不用于启动流程 - 它用于在流程中提供消息持久性。

您不需要前两个元素；只需配置消息驱动的适配器，destination-name="FORWARD"它就会从该队列接收消息。

另外，删除queueChannel; 不需要；该服务将在侦听器线程上调用。

message-driven-adapter->jmsInChannel->service-activator
