3.1.3.如图步骤,完成Discovery

3.1.4.如图步骤完成Service0,Service1类似

3.1.5.简单到爆炸有没有...........,接下来先启动Discovery,然后启动Service0和Service1

3.1.6.打开浏览器,访问 localhost:8080 ,8080是Discovery里配置的端口号.一切顺利的话,可以看到:

3.1.7.已经成功注册了service0,service1两个服务

3.2.网关demo: 光是注册了服务还不行,这里可以再配一个网关,让服务调用有统一的入口. 

3.2.1.通过上图配置后,首先启动Discovery,其次的服务和网关启动顺序随意.通过访问localhost:8083/service0/service0,即可看到,gateway帮我们转发了请求.

3.3.Ribbon负载均衡(未完待续)
