在阅读源代码之后，我发现org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient的{{1}}是：

org.springframework:spring-webflux:5.1.6.RELEASE

这是上面的第二个构造函数，需要一个public class ReactorNettyWebSocketClient implements WebSocketClient { private static final Log logger = LogFactory.getLog(ReactorNettyWebSocketClient.class); private final HttpClient httpClient; /** * Default constructor. */ public ReactorNettyWebSocketClient() { this(HttpClient.create()); } /** * Constructor that accepts an existing {@link HttpClient} builder. * @since 5.1 */ public ReactorNettyWebSocketClient(HttpClient httpClient) { Assert.notNull(httpClient, "HttpClient is required"); this.httpClient = httpClient; } ..... }对象与HttpClient不匹配。

org/springframework/cloud/gateway/config/GatewayAutoConfiguration$NettyConfiguration.class

此bug记录在Github上。

这是将起作用的Versions的正确组合之一：
父母：

<parent>
        <groupSId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.X</version> // I tested on <version>2.2.1.RELEASE</version>
</parent>

云版本： <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>

java.lang.NoSuchMethodError：org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient。<init>（Ljava / util / function / Consumer;）V
