在按照携程apollo的github上的配置进行配置好后启动ApolloApplication报了上面的错，查询发现，SpringCloud的Eureka的配置需要注意：
1、在默认设置下，Eureka服务注册中心也会将自己作为客户端来尝试注册它自己，所以我们需要禁用它的客户端注册行为。
禁止方式如下：
1 2 | eureka.client.register-with-eureka=falseeureka.client.fetch-registry=false |
如果不禁止的话，会得到如下错误：
1 2 3 | com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect2017-04-16 22:16:12.943 WARN 6864 --- [ main] c.n.d.s.t.d.RetryableEurekaHttpClient : Request execution failure2017-04-16 22:16:12.951 ERROR 6864 --- [ main] com.netflix.discovery.DiscoveryClient : DiscoveryClient_UNKNOWN/DESKTOP-MQ8D0C9:8761 - was unable to refresh its cache! status = Cannot execute request on any known server |
应该是因为当注册中心将自己作为客户端注册的时候，发现在server上的端口被自己占据了，然后就挂了。
因此全局搜索出Eureka的配置地方
加入如下代码：
重启不报错了。
