spring - Spring Web Flux(响应式(Reactive))功能路由与Kotlin一起无法正常工作

Question

您好有兴趣在Kotlin编写spring应用程序的好人。我正在使用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")}")) }
      }
    }
  }
}

不能按预期工作(至少不像我预期的那样:))

➜  ~ 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

这似乎是一个错误(因为"/{id}".route {...}据说正在使用RouterFunctions.nest)，但是我可能错了。欢迎您的想法和帮助。

我显然知道我可以通过编写/1/hello来使GET("/{id}/hello") { ... }工作，但是我对嵌套的.route { ...}变体很感兴趣，因为它支持我从另一个位置(如 map 等)添加嵌套路线的用例。
