Spring 集成未触发 int-http:outbound-gateway URL

Question

我有以下 spring 集成配置，它从从驱动器读取文件开始，将其转换为 java 对象并向 REST APT 发送 http GET 请求。前 2 个步骤在我的链中运行良好，但是当涉及到 int-http:outbound-gateway 步骤时，URL 永远不会被触发，也不会显示任何错误信息。应用程序保持运行状态，不显示任何错误消息。它永远不会转到 kbbCvsReadResponseTransformer class，我可以在其中检查从该 REST 服务收到的响应。可能是什么原因。我正在使用 spring-integration-4.1.2

<int-file:inbound-channel-adapter id="kbbFileInbound"
        channel="kbbInboundFileChannel"
        directory="file:/ftpguest/kbb-gm-rem/data"
        filename-pattern="GM_Remarketing_Pricing_Res_*.csv"
        auto-startup="true"
        prevent-duplicates="true">
        <int:poller fixed-rate="5000"/>
    </int-file:inbound-channel-adapter>

     <int:chain input-channel="kbbInboundFileChannel" output-channel="kbbCvsReadRequest">
        <int:transformer ref="kbbInputFileDataTransformer" />
    </int:chain>

    <int:chain input-channel="kbbCvsReadRequest" output-channel="cvsVehicleReadRequest">
        <int:transformer ref="kbbCvsUpdateRequestTransformer" />
    </int:chain>

    <int:chain input-channel="cvsVehicleReadRequest" output-channel="cvsVehicleReadResponse">
        <int:header-enricher>
            <int:header name="Content-Type" expression="'application/json'" />
        </int:header-enricher>
        <int-http:outbound-gateway http-method="GET" expected-response-type="com.fasterxml.jackson.databind.JsonNode"
            charset="UTF-8" request-factory="clientHttpRequestFactory" url="http://services.dev-sea.cobaltgroup.com/inventoryWebApp/rest/v1.0/vehicles/search?vin={vin};inventoryOwner={inventoryOwner}">
            <int-http:uri-variable name="vin" expression="payload.getVin()"/>
            <int-http:uri-variable name="inventoryOwner" expression="payload.getInventoryOwner()"/>
            <int-http:request-handler-advice-chain>
                <ref bean="retrier" />
            </int-http:request-handler-advice-chain>

        </int-http:outbound-gateway>

    </int:chain> 

     <int:chain input-channel="cvsVehicleReadResponse">
        <int:transformer ref="kbbCvsReadResponseTransformer" />
    </int:chain>


    <bean id="clientHttpRequestFactory"
        class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
        <property name="httpClient" value="#{httpComponentsMessageSender.httpClient}" />

    </bean>

    <bean id="kbbInputFileDataTransformer" class="com.cdk.dmg.kbb.integration.transformer.KbbInputFileDataTransformer"/>
    <bean id="kbbCvsUpdateRequestTransformer" class="com.cdk.dmg.kbb.integration.transformer.KbbCVSUpdateRequestTransformer" />
    <bean id="kbbCvsReadResponseTransformer" class="com.cdk.dmg.kbb.integration.transformer.KbbCVSReadResponseTransformer" />


    <!-- Need to use it from integration-context.xml, there are lot of issues with this file right now, so temporerly copied it here  -->
    <int:handler-retry-advice id="retrier" max-attempts="5" recovery-channel="errorChannel">
         <int:exponential-back-off initial="1000" multiplier="5.0" maximum="60000" />
    </int:handler-retry-advice>

Answer 1

如果没有任何日志确认，我们无法在这里帮助您。

请为 org.springframework.integration 分享 DEBUG 日志，以了解您的消息传输情况。

从另一边看，您似乎有一些错误，只需根据 <int:handler-retry-advice> 配置将其发送到 errorChannel。这就是为什么在那之后你没有收到任何对 cvsVehicleReadResponse 的回复...
