spring - channel 到多个出站 channel 适配器

Question

我有一个 channel

<int:channel id="myChannel" />

为此，我想将每条消息路由到多个出站 channel 适配器:

<int-jms:outbound-channel-adapter id="ocaOne" channel="myChannel" />
<int-jms:outbound-channel-adapter id="ocaTwo" channel="myChannel" />

我的理解是， channel 将有效地充当队列，但我希望每条消息都转到两个出站 channel 适配器。如何更改 channel 以充当主题？

编辑:

我相信答案是使用 PublishSubscribeChannel 但我不能确定(来源: http://docs.spring.io/spring-integration/reference/html/messaging-channels-section.html )

Answer 1

考虑使用PublishSubscribeChannel ( <publish-subscribe-channel> )改为:

The PublishSubscribeChannel implementation broadcasts any Message sent to it to all of its subscribed handlers.
