因此，要对相同的有效载荷进行3个并行呼叫，然后汇总结果，您需要研究一个散点图： https://docs.spring.io/spring-integration/docs/docs/current/current/current/referent/referent/reference/html/html/message-routing.html ＃散点机。
根据您的描述，您必须使用基于
PublishSubscribechannel（拍卖）的配置，并提供taskexecutor提供的配置。此通道的订阅者可以是普通的HTTP消息处理程序，服务激活程序，甚至是变压器，以在目标服务调用之前操纵有效负载。So, to make a 3 parallel calls for the same payload and then aggregate their result, you need to look into a Scatter-Gather pattern: https://docs.spring.io/spring-integration/docs/current/reference/html/message-routing.html#scatter-gather.
