Question

所以我正在开发一个拥有数百个流的spring集成应用程序。所有这些流程基本上代表了应用程序中的服务，如

Report Generation
Customer Search
Get Customer Transactions
Customer Activity Stream
etc.

我想验证发送到这些流的请求（基本上是否满足检查参数规范），因此我分别创建了另一个流来验证请求，以便发送到上述服务的任何请求都将首先通过验证流程。现在我想知道如何将其纳入服务流程。

详情请见下文。

验证流程---＆gt;

    <int:channel id="svcExeGovernorEntryLoggerChannel"/>

    <int:channel id="svcExeGovernorEntryRespChannel" >
        <int:interceptors>
            <int:wire-tap channel="svcExeGovernorEntryLoggerChannel"/>
        </int:interceptors>
    </int:channel>

    <int:transformer id="serviceExecutionGovernorEntry" ref="serviceExecutionGovernor" method="serviceExecutionEntry" input-channel="svcExeGovernorEntryReqChannel" output-channel="svcExeGovernorEntryRespChannel"/> 

    <int:logging-channel-adapter id="svcExeGovernorEntryLogger" channel="svcExeGovernorEntryLoggerChannel"  logger-name="svcExeGovernor-entry-logger" />

</beans>

我尝试使用如下的桥接器，但这些不起作用，它发送输出另一个服务。

<int:channel id="customerCrawlReqChannel">
        <int:interceptors>
            <int:wire-tap channel="customerCrawlLoggerChannel"/>
        </int:interceptors>
    </int:channel>
    <int:channel id="customerCrawlRespChannel">
        <int:interceptors>
            <int:wire-tap channel="customerCrawlLoggerChannel"/>
        </int:interceptors>
    </int:channel>
    <int:channel id="customerCrawlLoggerChannel"/>
    <int:channel id="customerCrawlResultChannel">
        <int:interceptors>
            <int:wire-tap channel="customerCrawlLoggerChannel"/>
        </int:interceptors>
    </int:channel>
    <int:channel id="customerCrawlJsonChannel"/>

    <http:inbound-gateway id="customerCrawlInboundGateway"
                          supported-methods="POST"
                          mapped-request-headers="User-Agent,Content-Type"
                          request-payload-type="java.lang.String"
                          path="/service/customercrawl"
                          reply-timeout="50000"
                          request-channel="customerCrawlReqChannel"
                          reply-channel="customerCrawlRespChannel">        
    </http:inbound-gateway>


    <int:bridge input-channel="customerCrawlReqChannel" output-channel="svcExeGovernorEntryReqChannel"/>


    <int:transformer id="customerCrawlPrvder" ref="crawlCustomerProviderService" method="crawlCustomer" input-channel="svcExeGovernorEntryRespChannel" output-channel="customerCrawlResultChannel"/>        


    <int:header-enricher input-channel="customerCrawlResultChannel"        output-channel="customerCrawlRespChannel">
        <int:header name="Content-Type" expression="'application/json'" />
    </int:header-enricher>       
    <int:logging-channel-adapter   
    id="customerCrawlLogger"channel="customerCrawlLoggerChannel"  logger-
    name="customerCrawl-logger"/>

请提出任何建议，提前谢谢。

如果svcExeGovernorEntryRespChannel有多个订阅者，则这些回复将循环分发给这些消费者;框架中没有任何东西可以告诉返回哪个订户流。

如果要在同一上下文中向多个流添加相同的验证流，请使用中流网关...

<int:service-activator 
            input-channel="customerCrawlReqChannel" 
            output-channel="customerCrawlReqAfterValidationChannel"
            ref="validationGW" />

<int:gateway id="validationGW"
            default-request-channel="svcExeGovernorEntryLoggerChannel"
            default-reply-channel="svcExeGovernorEntryRespChannel" />

这就像java中的方法调用，输入消息作为参数，输出消息是结果。

或者，您可以使用routing slip。验证后设置到下一个元素的路径，并从验证流程中的最后一个元素中删除输出通道。
