mule流中web服务调用的并发处理

重新表述了问题- 我有一个要求，在单个mule流中，我必须进行3次web服务调用（S1、S2、S3）

我的要求是调用Service1并等待它完成（或者如果不成功并返回，则处理错误），然后并发/同时解除Service2和Service3。我想等待Service1的响应，因为我对Service2和Service3的调用使用Service1的部分响应作为输入。因此，我的mule流应该在触发Service2和Service3之前等待Service1的响应。但是如果Service1成功，它应该同时调用Service2和Service3。 即使Service2和Service3中的一个失败，我也希望继续，而不是这个流的调用者失败/出错

任何类型的示例代码/链接都很好。

如果您想一个接一个地调用3个服务，并且任何服务的故障都不会影响剩余的流，那么您可以尝试以下类型的设计

<flow name="main_flow">
    <flow-ref name="private_flow_call_to_service_1"></flow-ref>
    <flow-ref name="private_flow_call_to_service_2"></flow-ref>
    <flow-ref name="private_flow_call_to_service_3"></flow-ref>
</flow>

<flow name="private_flow_call_to_service_1" processingStrategy="synchronous">
    <!-- call service 1  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 1 -->
    </catch-exception-strategy>
</flow>

<flow name="private_flow_call_to_service_2" processingStrategy="synchronous">
    <!-- call service 2  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 2 -->
    </catch-exception-strategy>
</flow>

<flow name="private_flow_call_to_service_3" processingStrategy="synchronous">
    <!-- call service 3  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 3 -->
    </catch-exception-strategy>
</flow>

希望这有帮助。

Mule分散-聚集组件用于并发执行多个流。 该组件已在Mule 3.5中引入

为了确保一个流的故障不会影响另一个流，您可以将流包装在

块中

您的问题有点令人困惑。它是并行运行服务还是顺序运行服务（一个接一个）？

<flow name="main_flow">
    <flow-ref name="private_flow_call_to_service_1"></flow-ref>
    <flow-ref name="private_flow_call_to_service_2"></flow-ref>
    <flow-ref name="private_flow_call_to_service_3"></flow-ref>
</flow>

<flow name="private_flow_call_to_service_1" processingStrategy="synchronous">
    <!-- call service 1  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 1 -->
    </catch-exception-strategy>
</flow>

<flow name="private_flow_call_to_service_2" processingStrategy="synchronous">
    <!-- call service 2  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 2 -->
    </catch-exception-strategy>
</flow>

<flow name="private_flow_call_to_service_3" processingStrategy="synchronous">
    <!-- call service 3  -->
    <catch-exception-strategy>
        <!-- Catch and handle any error or failure while making call to service 3 -->
    </catch-exception-strategy>
</flow>
