Spring 来自收件人列表路由器的异步调用

我是SI的新手，但现在读了很多书。我必须从flow中再调用1个，这已经实现了。我需要这个调用不被阻塞，这样链就不会等待它的执行——它被发送到另一个系统，这个系统可能已经关闭

我需要向两个通道发送消息，所以我使用了收件人列表路由器，没有任何条件

<int:recipient-list-router id="processEngineRouter" input-channel="newApplicationChannel">
    <int:recipient channel="finishFlowChannel"/>
    <int:recipient channel="processEngineChannel"/>
</int:recipient-list-router>

和

其中

任务

前缀来自版本3.1，没有其他设置

路由器的输入通道为

<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>

---

它工作得很好

如您所见，

…exec-2

线程在

apiReplyChannel

上发送回复，然后在

进程引擎通道上执行发送（发送前和发送后是背靠背的），并将其交给线程
任务执行器-1
，然后开始处理该通道链、转换器等上的流

…exec-2
线程继续完成其工作（以
APIRestChannel
上的postSend结束）

但是，我发现processEngineChannel链上没有输出通道-框架将尝试将该回复发送到消息的
replyChannel
标题中的任何内容-如果要放弃该回复，应将该链的
输出通道设置为nullChannel。
不清楚您的意思“input newApplicationChannel也会等待processEngineChannel完成，”-通道不会“等待”任何内容。与往常一样，打开调试日志记录（包括log4j的线程-
%t
-在调试这些东西时总是有帮助的。注意，当从“newApplicationChannel”调用路由器时，进程直到“processEngineChannel”完成才结束。我可以在调试中看到，“finishFlowChannel”postSend（）调用了，但我看到，我也必须等待“processEngineChannel”完成。我想调用“processEngineChannel”，而不是等待它运行。我需要查看上游和下游（两条腿）你所描述的对我来说没有任何意义；调用线程向执行线程进行异步切换，任何东西都不应该“等待”"。您还应该显示您的
taskExecutor
配置。例如，如果执行器是
SyncTaskExecutor
，则当然不会进行线程切换。我更改了代码。如果我需要以某种方式更改执行器，请告诉我。我仍然不明白为什么会有等待-除非
naR的上游有任何更改equestChannel
正在等待回复，而finishFlowChannel
上的流没有生成回复。但这不能通过添加延迟器来解决。我想我需要查看调试日志（包括log4j的线程
%t
）。
