服务消费者

创建项目sercice-order

application.yml配置

eureka:

  client:

    serviceUrl:

      defaultZone: http://localhost:8888/eureka/

server:

  port: 8764

spring:

  application:

    name: service-order

编写service,调用service-member

@SuppressWarnings("unchecked")

@Service

public class MemberService {

      @Autowired

      RestTemplate restTemplate;

 

      public List<String> getOrderByUserList() {

            return restTemplate.getForObject("http://service-member/getUserList", List.class);

      }         

}

演示效果

@EnableEurekaClient

@SpringBootApplication

public class AppOrder {

 

      public static void main(String[] args) {

            SpringApplication.run(AppOrder.class, args);

      }

 

      @Bean

      @LoadBalanced

      RestTemplate restTemplate() {

            return new RestTemplate();

      }

 

}

在工程的启动类中,通过@EnableDiscoveryClient向服务中心注册；并且向程序的ioc注入一个bean: restTemplate;并通过@LoadBalanced注解表明这个restRemplate开启负载均衡的功能。
