如何在使用apache camel scala dsl时进行“交易”工作？

我开始使用scala DSL并且非常喜欢它。

我目前有一个混合java和scala的项目。

我在java中有正确的事务处理。

如果我尝试使用scala进行交易路由，则无法启动驼峰上下文。

以下是未启动的示例路线：

"amq:queue:myQueue" ==> {
    routeId("myTransactedRoute")
    transacted("JMS_PROPAGATION_REQUIRED")
    -->("log:foo")
}

其中“JMS_PROPAGATION_REQUIRED”是我的交易策略，适用于java。

我做错了吗？

org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route myTransactedRoute at: >>> From[amq:queue:myQueue] <<< in route: Route(myTransactedRoute)[[From[amq:queue:myQueue... because of Route myTransactedRoute has no output processors. You need to add outputs to the route such as to("log:foo").

在仔细查看代码之后，我发现了一些看起来像故障的东西，我正在测试并且如果有效则会执行拉取请求。
