Question

我使用SpringIntegration 2.2.1时遇到问题：我想使用JMS（WMQ作为代理）在两个不同系统之间交换消息，在JBoss AS 7中实现请求/回复模式（作为同步消息传递）。

我的xml配置文件包含：

1）出站配置：

<bean id="BOHAdjustmentConverter" class="com.test.interoperabilitytracking.internal.BOHAdjustmentConverter" />

<si:publish-subscribe-channel id="outboundBOHAdjustmentChannel" task-executor="integrationTaskExecutor" />
<si:publish-subscribe-channel id="outboundBOHAdjustmentErrorChannel" task-executor="integrationTaskExecutor" />

<si:gateway id="outboundAspectGateway" service-interface="com.test.interoperabilityframework.service.RequestGateway"
    default-request-channel="outboundBOHAdjustmentChannel" 
    default-reply-channel="outboundBOHAdjustmentReplyChannelEnriched" 
    error-channel="interoperabilityError"
    default-reply-timeout="20000" />

<!-- INTEROPERABILITY FRAMEWORK GATEWAY -->
<bean id="outboundBOHAdjustmentAspectBean" class="com.test.interoperabilityframework.service.impl.OutboundAspect">
    <property name="requestGateway" ref="outboundAspectGateway" />
    <property name="outboundEnrichedErrorChannel" ref="interoperabilityError" />
    <property name="defaultChannelTimeout" value="1000" />
</bean>

<aop:config>
    <aop:aspect id="outboundBOHAdjustmentAspect" ref="outboundBOHAdjustmentAspectBean">
        <aop:pointcut id="theExecutionOfCreateUpdateBOHAdjustmentMethod"

        <aop:around pointcut-ref="theExecutionOfCreateUpdateBOHAdjustmentMethod" method="sendReceiveAndReturnWithGateway" />
        <aop:after-throwing pointcut-ref="theExecutionOfCreateUpdateBOHAdjustmentMethod" throwing="error" method="handleError" />
    </aop:aspect>
</aop:config>

<si:header-enricher input-channel="outboundBOHAdjustmentChannel" output-channel="outboundBOHAdjustmentChannelEnriched">

    </si:interceptors>
</si:channel>

    <property name="channel" ref="outboundBOHAdjustmentChannel" />

2）我的入站配置文件包含：

<bean id="inboundBOHAdjustmentContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <property name="connectionFactory" ref="leoEcoSystemConnectionFactory" />
    <property name="destination" ref="outboundBOHAdjustmentDestination" />

<si:channel id="inboundBOHAdjustmentReplyChannelEnriched">

        <si:wire-tap channel="interoperabilityResult" />
    </si:interceptors>
</si:channel>

<si-jms:inbound-gateway id="inboundBOHAdjustementGateway" acknowledge="auto" 
    container="inboundBOHAdjustmentContainer"

</si:chain>

<si:service-activator input-channel="inboundBOHAdjustmentChannelEnsureTracking" output-channel="interoperabilityResult" ref="service"
    method="createUpdateBOHAdjustment" />

3）我省略了一些其他的bean，比如converter和jaxb provider。 connectionFactory是配置到JBoss AS 7 standalone.xml的队列上的JNDI名称，这是由WMQ实现的JMS ConnectionFactory的实例。

4）我有其他配置文件和其他类来执行跟踪。

我想知道：

调用服务时，启动方面，网关发送消息并等待响应;
在频道上有一个henricher和一些其他服务激活器。此时，我会在数据库上保留一条记录来跟踪direction =“出站”和directionType =“请求”;
消息到达队列;
另一个系统上的入站网关，对消息进行解除队列并将消息应用于其逻辑。在这个频道上有标题增强。在这里，我将跟踪direction =“入站”和directionType =“请求”;
将回复消息（也是相同的消息）发送到另一个带有标题扩展器的通道。此时我想坚持direction =“入站”和directionType =“回复”;
回复邮件到达出站网关。在这个频道上我有另一个标题增加，我会坚持direction =“出站”和directionType =“回复”;

问题问题是答复在入站时不起作用也不在ountbound中。 Spring Integration文档解释说，要执行此方案，出站和入站都必须是请求/回复，并建议将outbount-gateway和inbound-gateway与回复通道一起使用，因为它们是双向的。不幸的是，我不明白为什么它不能正常工作，servlet在回复时被阻止，当我尝试转换Spring消息时，我从未收到directionType的“回复”值。
