SpringCloud工作笔记035---Zuul网关异常：com.netflix.zuul.exception.ZuulException: Forwarding error

JAVA技术交流QQ群：170933152

最近真是被这个分布式的权限设计，搞的郁闷，项目紧，任务重，天天加班

先说背景，项目要实现微服务的权限验证，这里：

sc-gateway 网关

网关要配置

E:\IdeaWkSpace\SmartCommunity\sc-gateway\src\main\resources\application.properties

spring.application.name=sc-gateway
server.port=8020

#zuul.host.socket-timeout-millis=60000
#zuul.host.connect-timeout-millis=60000

#zuul.routes.api-a.path=/producer/**
#zuul.routes.api-a.url=spring-cloud-producer

#下面这里就是原因了，这里配置了权限验证的微服务是sc-auth ，地址用/auth/**
#也就是，当访问/auth开头的api，就被网关自动转到sc-auth这个微服务上去了
zuul.routes.sc-auth.path=/auth/**
#zuul.routes.auth.sensitive-headers=""
zuul.routes.sc-auth.service-id=sc-auth
#zuul.add-proxy-headers=true
#security.basic.enabled=false
management.security.enabled=false

#这里是配置的服务提供者，也就是其他微服务，调用接口的
zuul.routes.sc-admin.path=/producer/**
#zuul.sensitive-headers=
zuul.routes.sc-admin.service-id=sc-admin





eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

#暂时先不监控接口调用速度监测
#spring.zipkin.base-url=http://localhost:9000
#spring.sleuth.sampler.percentage=1.0

 

然后启动，sc-gateway微服务，启动E:\IdeaWkSpace\SmartCommunity\sc-regcenter微服务

启动：E:\IdeaWkSpace\SmartCommunity\sc-admin微服务，启动：E:\IdeaWkSpace\SmartCommunity\sc-auth微服务

-----------------------------------------------

访问：

http://localhost:8020/auth/oauth/token 就报错了

注意下面的错误就是因为：

没有启动：E:\IdeaWkSpace\SmartCommunity\sc-auth导致的，因为通过后边看异常也能看出来，

异常的原因是，网关，去找sc-auth微服务，但是sc-auth微服务没有启动，而是超时了，所以就报了

下面的错误

----------------------------------------------------------------------------------------

下面这个异常：

 com.netflix.zuul.exception.ZuulException: Forwarding error

先看看网上的说法：

https://blog.csdn.net/heroguo007/article/details/78134678

说是下面这样：不行啊，这个时候我都不知道ribbon是啥，好不好。。 只知道是做负载均衡的，接下来再去搞定它

ribbon:
  ReadTimeout: 60000
  ConnectTimeout: 60000

好了，不扯了，下面
