红帽全球峰会297.4. 使用 Request Reply
SEDA 组件支持使用 Request Reply，调用者将等待 Async 路由完成。例如：
from("mina:tcp://0.0.0.0:9876?textline=true&sync=true").to("seda:input");
from("seda:input").to("bean:processInput").to("bean:createResponse");
from("mina:tcp://0.0.0.0:9876?textline=true&sync=true").to("seda:input");
from("seda:input").to("bean:processInput").to("bean:createResponse");
在上面的路由中，我们在端口 9876 上有一个 TCP 侦听器，它接受传入的请求。请求被路由到 seda:input 队列。因为它是一个 Request Reply 消息，我们等待响应。当 seda:input 队列上的消费者完成后，它会将响应复制到原始消息响应。
注意
在 2.2: 只适用于使用 Request Reply over SEDA 或 VM 的 2 端点 只适用于 2 个端点。您无法通过 发送到 A
