Spring Cloud Gateway 不适用于 @Bean Discovery

Question

我遵循 Spring Tips: Spring Cloud Gateway。但是我的网关应用程序不会从服务注册（尤里卡）创建路由。带有 2 个参数的 DiscoveryClientRouteDefinitionLocator 构造函数。它不是从 Eureka 服务器路由的网关应用程序。我一直在尝试更改 pom.xml 中的版本，但我使用的是 RELEASE。该Application.java@SpringBootApplicationpublic class GatewayApplication {    @Bean    DiscoveryClientRouteDefinitionLocator discoveryRoutes(DiscoveryClient dc, DiscoveryLocatorProperties dlp) {        return new DiscoveryClientRouteDefinitionLocator(dc, dlp);    }    public static void main(String[] args) {        SpringApplication.run(GatewayApplication.class, args);    }}DiscoveryClientRouteDefinitionLocator 的构造函数现在使用 2 个参数，而不是像 Spring Tips: Spring Clou Gateway 中的 1 个参数。该application.property：spring.application.name=gatewayserver.port=8081eureka.client.register-with-eureka=true我的pom.xml：<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion><groupId>com.hcl.cnp</groupId><artifactId>gateway</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>gateway</name><description>Demo project for Spring Boot</description><parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>2.0.3.RELEASE</version>    <relativePath/> <!-- lookup parent from repository --></parent><properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>    <java.version>1.8</java.version>    <spring-cloud.version>Finchley.RELEASE</spring-cloud.version></properties><dependencies>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-actuator</artifactId>    </dependency>

Answer 1

构造函数DiscoveryClientRouteDefinitionLocator (DiscoveryClient, DiscoveryLocatorProperties) 已弃用

我建议你使用：

ReactiveDiscoveryClient代替DiscoveryClient

@Bean

DiscoveryClientRouteDefinitionLocator discoveryRoutes(ReactiveDiscoveryClient rdc,

        DiscoveryLocatorProperties dlp) {

    return new DiscoveryClientRouteDefinitionLocator(rdc, dlp);

}

其他的事情，你应该将你的application.proporty重命名为application.properities
