第一节第一节第一节第一节第一次
所附文档中存在错误。
我在pom.xml和yml文件中添加了netflixEureka 依赖项。

这是yml文件。

spring:
  application:
    name: GATEWAY-SERVICE
  cloud:
    gateway:
      routes:
        - id: order-service
          uri: lb://ORDER-SERVICE
          predicates:
            - Path=/order/**
        - id: payment-service
          uri: lb://PAYMENT-SERVICE
          predicates:
            - Path=/payment/**

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka/
  instance:
    hostname: localhost

server:
  port: 8989

此文件为pom.xml

我希望我的配置可以帮助你。这是客户端的YML文件的样子：

###############################################################
# SERVER CONFIG
###############################################################
server:
  port: 8083

spring:
  application:
    name: gateway

###############################################################
# EUREKA CONFIG
###############################################################
eureka:
  client:
    registry-fetch-interval-seconds: 1
    eureka-connection-idle-timeout-seconds: 30000
    register-with-eureka: true
    fetch-registry: true
    serviceUrl:
      defaultZone: http://load-balancer:8070/eureka/
  instance:
    prefer-ip-address: true
    lease-renewal-interval-in-seconds: 1

ribbon:
  ServerListRefreshInterval: 1000

另外，别忘了在微服务的主类上方添加**@EnableEurekaClient**annotation：

@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
public class GatewayApplication {
...
}

我将依赖项添加到Gradle：

dependencies {
    ...
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
    ...
}

这是Eureka 服务器微服务的一个例子：

spring:
  application:
    name: load-balancer

server:
  port: 8070

  tomcat:
    max-threads: 100000

ribbon:
  eureka:
    enabled: true
  ReadTimeout: 60000
  connection-timeout: 30000
  NIWSServerListClassName: com.netflix.loadbalancer.ConfigurationBasedServerList
  NFLoadBalancerRuleClassName: com.netflix.loadbalancer.WeightResponseTimeRule

eureka:
  server:
    enable-self-preservation: false
    response-cache-update-interval-ms: 1000
  instance:
    prefer-ip-address: true
  client:
    register-with-eureka: false
    fetch-registry: false

别忘了在Eureka服务器应用程序的主类上方添加**@EnableEurekaServer**annotation：

@SpringBootApplication
@EnableEurekaServer
public class LoadBalancerApplication {
...
}

最后，我将依赖项添加到Gradle：

dependencies {
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-server'
    ...
}
