集成Eureka-server和Eureka-cliet以及遇到的各种问题总结
1.Springboot和Springclould版本问题？第一种情况：启动报错，启动不了aplication，版本有问题不兼容第二种情况：正常启动，各种配置没有问题，注册服务中心找不到，比如服务端配置：server.port=8888eureka.instance.hostname=localhost#代表不向注册中心注册自己eureka.client.register-wi...
·
环境配置Eureka-server
application.properties配置：
server.port=8761
eureka.instance.hostname=localhost
#代表不向注册中心注册自己
eureka.client.register-with-eureka=false
#维护服务实例，不需要检索服务
eureka.client.fetch-registry=false
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka

1.Springboot和Springclould版本问题？
第一种情况：启动报错，启动不了aplication，版本有问题不兼容
第二种情况：正常启动，各种配置没有问题，注册服务中心找不到，比如服务端配置：
server.port=8888
eureka.instance.hostname=localhost
#代表不向注册中心注册自己
eureka.client.register-with-eureka=false
#维护服务实例，不需要检索服务
eureka.client.fetch-registry=false
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka

启动项目：
This application has no explicit mapping for /error, so you are seeing this as a fallback.
内心是崩溃的，网上各种找都是说版本不一致，启动就会报错，我就坚信了，于是弄了几天都没找到问题，springclould官方给出的springboot和springcloud给出的版本也是这样的,，但是版本依然是有问题，需要换版本。
2.Eureka-clinet配置没有什么问题，和别人使用的配置是一样的，但是Finchley.RELEASE版本启动的客户端的时候是这样的
控制台显示没有成功的信息
Registered instance EUREKA-SERVER/edz-PC:eureka-server:9090 with status DOWN (replication=false)
控制台信息显示成功的信息
DiscoveryClient_EUREKA-SERVER/edz-PC:eureka-server:9090 - registration status: 204
使用Finchley.RELEASE版本一定要引入web
