java - 在 Kotlin 中引用重载的 Java 方法

Question

我想知道如何从 Kotlin 中的 Java 类中引用重载方法。

比如在界面WebClient共有三种get方法:

  HttpRequest<Buffer> get(int port, String host, String requestURI);
  HttpRequest<Buffer> get(String host, String requestURI);
  ...

在 kotlin 中，我想用三个参数引用一个:

val methodReference : WebClient.(port : Int, host: String?, requestUrl: String?) -> HttpRequest<Buffer> = WebClient::get

但我收到以下错误:

None of the following functions can be called with the arguments supplied: 
public abstract operator fun get(p0: Int, p1: String!, p2: String!): HttpRequest<Buffer!>! defined in io.vertx.ext.web.client.WebClient
public abstract operator fun get(p0: String!): HttpRequest<Buffer!>! defined in io.vertx.ext.web.client.WebClient
public abstract operator fun get(p0: String!, p1: String!): HttpRequest<Buffer!>! defined in io.vertx.ext.web.client.WebClient

有任何想法吗？

尝试获取这样的引用:

val methodReference: WebClient.(Int, String, String) -> HttpRequest<Buffer>? = WebClient::get
