Question

我有以下配置

<int:chain input-channel="requestsChannel">
    <int:splitter ref="aBean" method="aMethod" />
    <!-- routing to the appropriate processing channels -->
    <int:recipient-list-router default-output-channel="feedRequestChannel">
        <int:recipient channel="whateverRequestChannel" selector-expression="payload.source == 'whatever'"/>
    </int:recipient-list-router>
</int:chain>

<int-http:outbound-gateway request-channel="feedRequestChannel" reply-channel="feedResponseChannel"
    url="{source}"
    http-method="GET" expected-response-type="java.lang.String">
    <int-http:uri-variable name="source" expression="payload.getSource()" />
</int-http:outbound-gateway>

现在我收到了错误

这不是问题。 aMethod会返回两个对象的集合，一个遍历feedRequestChannel，另一个遍历whateverRequestChannel。但是当我得到上述错误时，第二个对象不再被处理。

是否有任何配置以便我可以忽略错误？

Answer 1

由于<splitter>生成了几封要发送的消息，如果output-channel thread-shift executor queue，<request-handler-advice-chain>等等，则会很好。

第一条消息的错误不会影响第二条消息。

从另一方面来说，如果您需要单线程（逐个发送/处理），您可以使用<outbound-gateway>为每个ExpressionEvaluatingRequestHandlerAdvice玩一点，以使用trapException = true扼杀错误{{1}}
