负载平衡器没有可用于客户端的服务器：会议

当我尝试通过 Zuul 网关访问服务时，Zuul 无法将请求转发到相应的服务。以下错误是我面临的：meeting

1. nettflix.zuul.exception.ZuulException： Forwarding error
2. 由以下原因导致：com.netflix.client.ClientException： Load Balancer 没有可用于客户端的服务器：会议

让我分享一下服务的 application.yml，eureka 和 zuul gateway。

尤里卡客户： Application.yml

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
    lease-renewal-interval-in-seconds: 300
  client:
    register-with-eureka: false
    fetch-registry: true
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

ZuulGateWay： application.yml

server:
  port: 8085

spring:
  application:
    name: gatekeeper


zuul:
  routes:
    meeting: /meeting/**
    serviceId: meeting

ribbon:
  eureka:
    enabled: false

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

ZuulGateWay： SpringBootApplication

package com.sagarp.gatekeeper;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
public class MeetingApplication {

    public static void main(String[] args) {
        SpringApplication.run(MeetingApplication.class, args);
    }
}

我的服务类（会议）： Application.yml

server:
  port: 0
spring:
  application:
    name: meeting
  datasource:
    url: jdbc:mysql://localhost:3306/sagarp?useSSL=false
    username: myUserName
    password: myPassWord
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
    hibernate:
     ddl-auto: update

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    lease-renewal-interval-in-seconds: 5

我的服务类（会议）： SpringBootApplication

package com.sagarp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class MeetingApplication {

    public static void main(String[] args) {
        SpringApplication.run(MeetingApplication.class, args);
    }
}

如您所见，该配置可确保 eureka 客户端发现我的所有服务。

在eureka控制台中，我已经验证了相同的内容，并且两者都可见。zuul gatewaymy service(meeting)
