Spring Web Flux（反应式）功能路由与Kotlin无法正常工作

你好有兴趣在Kotlin编写Spring应用程序的人。 我正在玩Spring Boot 2.0.0快照和spring-webflux 。 这段代码：

 @Component class TestRouter() : RouterFunction<ServerResponse> { override fun route(request: ServerRequest) = route(request) { "/".route { GET("/hello") { ServerResponse.ok().body(BodyInserters.fromObject("World")) } "/{id}".route { GET("/hello") { ServerResponse.ok().body(BodyInserters.fromObject("World ${request.pathVariable("id")}")) } } } } } 

不按预期工作（至少如我所料:)）

 ➜ ~ curl -i http://localhost:8080/hello HTTP/1.1 200 OK transfer-encoding: chunked Content-Type: text/plain;charset=UTF-8 World 

但：

 ➜ ~ curl -i http://localhost:8080/1/hello HTTP/1.1 404 Not Found content-length: 0 

工作案例跟踪：

不工作情况跟踪：

这看起来像一个错误（因为"/{id}".route {...}据说是使用RouterFunctions.nest），但我可能是错的。 您的想法和帮助是受欢迎的。

我明显知道我可以通过编写GET("/{id}/hello") { ... }来完成/1/hello工作，但是我对嵌套的.route { ...}变体感兴趣我从另一个位置（如地图等）添加嵌套路线的用例。
