解决：com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused:

翻译过来是连接被拒绝

1）、启动一个Eureka注册中心报错如下

`com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect
at com.sun.jersey.client.apache4.ApacheHttpClient4Handler.handle(ApacheHttpClient4Handler.java:187) ~[jersey-apache-client4-1.19.1.jar:1.19.1]
at com.sun.jersey.api.client.filter.GZIPContentEncodingFilter.handle(GZIPContentEncodingFilter.java:123) ~[jersey-client-1.19.1.jar:1.19.1]
at com.netflix.discovery.EurekaIdentityHeaderFilter.handle(EurekaIdentityHeaderFilter.java:27) ~[eureka-client-1.9.17.jar:1.9.17]
at com.sun.jersey.api.client.Client.handle(Client.java:652) ~[jersey-client-1.19.1.jar:1.19.1]

`2）配置采用yml语法加上

client:
# 此应用为注册中心，false：不向注册中心注册自己。
register-with-eureka: false
# 注册中心职责是维护服务实例，false：不检索服务
fetch-registry: false

3）启动项目即可
