5.    运行测试

启动  Eureka   服务注册中心，参考  https://www.cnblogs.com/jonban/p/eureka.html

启动  MicroService  微服务， 参考   https://www.cnblogs.com/jonban/p/microservice.html

启动  Zuul服务，运行 ZuulStarter.java

浏览器输入URL

http://192.168.1.102:10000/service/getHostMessage/hello

返回数据如下：

{"hostname":"F6RK2EXYAFARPPS","hostAddress":"192.168.1.102","id":"hello"}

截图如下：

搭建成功！

查看Eureka  服务注册情况，输入Eureka服务URL

http://192.168.1.102:8080/
