依次将`microservice-eureka-server`、`microservice-provider-user`和`microservice-gateway-zuul`服务启动起来，控制面板如下图：  然后，访问网关 9000 端口的 URL：`http://localhost:9000/microservice-provider-user/users/2`，会发现请求被转发到了`microservice-provider-user`服务的`/users/{id}`端点； ~~~bash curl http://localhost:9000/microservice-provider-user/users/2 ~~~ ~~~json { "id": 2, "username": "account2", "name": "李四", "age": 28, "balance": 180 } ~~~ 因为我们之前引入了 Eureka 并将 Zuul 注册到了 Eureka，Zuul 根据刚刚请求中的`microservice-provider-user`匹配路由并转发到该服务了。
