配置：application.yml

server:  port: 80spring:  application:    name: cloud-sonsumer-order  cloud:    zookeeper: #注册到zookeeper      connect-string: localhost:2181

配置类：

@Configurationpublic class ApplicationContextConfig {
       @Bean    @LoadBalanced    public RestTemplate getRestTemplate(){
           return new RestTemplate();    }}

Controller:

@SpringBootApplication@EnableDiscoveryClientpublic class OrderZKMain80 {

           SpringApplication.run(OrderZKMain80.class, args);    }}

启动类：

@SpringBootApplication@EnableDiscoveryClientpublic class OrderZKMain80 {
       public static void main(String[] args) {
           SpringApplication.run(OrderZKMain80.class, args);    }}

测试

启动zookeeper，然后启动两个微服务：

连接zookeeper，可以看到服务已经注册：

在80端口调用8004的服务：

访问：http://localhost/consumer/payment/zk
