Question

我有两个int-http：inbound-gateway with path，如下所述。并且指向相同的请求通道但具有不同的回复通道。

 http://localhost:8080/XYZ/ABCService/query  -- i expected to call http:inbound-gateway with id ="XYZ"

    http://localhost:8080/ABCService/query  - i expected to call http:inbound-gateway with id ="default"

但是当我向

提出请求时，它的不一致性是什么

 http://localhost:8080/XYZ/ABCService/query

它正在呼叫＆＃34;默认＆＃34;网关其他时间它的呼叫＆＃34; XYZ＆＃34;即不一致。或者不确定它是否可以正确调用，而是响应不同的回复频道？

我正在使用DispatcherServlet.Below我的spring-integration.xml

     <int-http:inbound-gateway id="default"
                path="/*Service/query"
                request-channel="RequestChannel" reply-channel="ResponseChannel"
                supported-methods="POST" reply-timeout="5000" request-payload-type="java.lang.String"
                error-channel="ErrorChannel" mapped-request-headers="xyz-*, HTTP_REQUEST_HEADERS">
                <int-http:header name="reply-type" expression="'DEFAULT'" />
         </int-http:inbound-gateway>


            <int-http:inbound-gateway id="XYZ"
                path="/XYZ/*Service/query"
                request-channel="RequestChannel" reply-channel="XYZExportTransformedChannel"
                supported-methods="POST" reply-timeout="5000" request-payload-type="java.lang.String"
                error-channel="ErrorChannel" mapped-request-headers="xyz-*, HTTP_REQUEST_HEADERS">
                 <int-http:header name="reply-type" expression="'ABC'" />
            </int-http:inbound-gateway>

    <!--All endpoints  output chanlle is CommonResonseChannel -->
    <int:channel id="CommonResponseChannel">

        </int:channel>

        <!-- final router -->

          <int:header-value-router input-channel="CommonResponseChannel"
                header-name="reply-type">
                <int:mapping value="DEFAULT" channel="ResponseChannel" />
                <int:mapping value="ABC" channel="XYZResponseChannel" />
            </int:header-value-router>

           <int:channel id="ResponseChannel">

            </int:channel>

     <int:channel id="XYZResponseChannel">

            </int:channel>

<int:transformer input-channel="XYZResponseChannel"
        output-channel="XYZExportTransformedChannel" id="TransformerChannel"
        ref="objToCSVTransformer"></int:transformer>

    <bean class="SomeTransformer"
        id="objToCSVTransformer"></bean>

<int:channel id="XYZExportTransformedChannel" />




    I have opened this question before not not very clear.Not sure how to update that.So opened new one.

Answer 1

您不应该以这种方式配置回复频道;它可能会导致不可预测的结果。

reply-channel只是桥接到消息replyChannel标题，因此它通常可以正常工作，但它是不可预测的，因为在网关首次收到消息时设置了网桥。

相反，只需省略网关上的reply-channel属性，让框架使用replyChannel标题直接路由回复。

而不是路由器，配置“无处可通”（<bridge/> input-channel= CommonResponseChannel"而不是output-channel。

或者只是省略最后一个端点上的output-channel（而不是发送到CommonResponseChannel）。
