我是 SI 的新手，但现在已经阅读了很多。我必须从流程中再打 1 个电话，这已经实现了。我需要这个调用是非阻塞的，所以链不会等待它的执行——它被发送到另一个系统，它可能已经关闭。
我需要向 2 个频道发送消息，所以我没有任何条件地使用了接收者列表路由器。
<int:recipient-list-router id="processEngineRouter" input-channel="newApplicationChannel">
<int:recipient channel="finishFlowChannel"/>
<int:recipient channel="processEngineChannel"/>
</int:recipient-list-router>
完成finishFlowChannel后，processEngineChannel调用 。这很好，但问题是，输入newApplicationChannel确实也在等待processEngineChannel完成，即使我正在使用 Executor 通道，这应该是异步的。
<int:channel id="finishFlowChannel"/>
<int:chain input-channel="finishFlowChannel" output-channel="apiReplyChannel">
<!-- create response -->
<int:transformer ref="xxToYYTransformer"/>
</int:chain>
<int:channel id="processEngineChannel">
<int:dispatcher task-executor="taskExecutor"/>
</int:channel>
<int:chain input-channel="processEngineChannel">
<!-- transform x to y -->
<int:transformer ref="xToYTransformer"/>
<!-- call PE -->
<int:gateway request-channel="peRCh"/>
</int:chain>
并且前缀来自http://www.springframework.org/schema/task/spring-task.xsd 3.1版，没有其他设置<task:executor id="taskExecutor"/>。task
路由器的输入通道是
<int:channel id="newApplicationChannel"/>
<int:channel id="naRequestChannel"/>
<int:chain input-channel="naRequestChannel" output-channel="newApplicationChannel">
<int:transformer>
...
</int:transformer>
<si-xml:unmarshalling-transformer unmarshaller="xxMarshaller"/>
<!-- enrich header with necessary data -->
<int:header-enricher>
...
</int:header-enricher>
<!-- transform xx to yy -->
<int:transformer ref="xxToYyTransformer"/>
<!-- call yyy service -->
<int:gateway request-channel="yyyServiceRequestChannel"/>
</int:chain>
当我将它添加delayer到链中时，它起作用了，但这不是很好的解决方案。
我的问题是，我用错了 taskExecutor 吗？我还能如何使调用异步？我不想使用队列，因为我不需要重复轮询事件。
