SpringCloud服务发现-ribbon

创建springboot应用，添加依赖

• eureka server
• ribbon 

配置application.yml

server:
  port: 8002

spring:
  application:
    name: api-order-add-feign

eureka:
  client:
    service-url:
      defaultZone: http://yzx35515:yzx35515@localhost:8761/eureka

在启动类添加 @EnableDiscoveryClient 注解

@SpringBootApplication
@EnableDiscoveryClient
public class ApiOrderAddApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApiOrderAddApplication.class, args);
    }

}

服务调⽤

配置RestTemplate

@Configuration
public class AppConfig {

    @LoadBalanced//启用Ribbon（负载均衡）
    @Bean
    public RestTemplate restTemplate(){
        return new RestTemplate();
    }

}

在Service中注⼊RestTemplate对象调⽤服务

@Service
public class OrderAddServiceImpl implements OrderAddService {

    @Autowired
    private RestTemplate restTemplate;

    @Override
    public ResultVO saveOrder(Order order) {
        //1.调用order-add服务进行保存
        ResultVO vo = restTemplate.postForObject("http://order-add/order/add", order, ResultVO.class);
        System.out.println(vo);
        //2.调用orderitem-add保存
        //3.调用stock-updata修改商品库存
        //4.调用shopcart-del删除购物车记录
        return vo;
    }
}
