eureka 消费服务

1：pom

    <!---  eureka-client  -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

2：yml

eureka:
  client:
    fetch-registry: true
    register-with-eureka: true
    service-url:
      defaultZone: http://localhost:7001/eureka

3：注解

@EnableEurekaClient
@SpringBootApplication
public class OrderMain80 {

    public static void main(String[] args) {
        SpringApplication.run(OrderMain80.class);
    }
}

端口分配 80

4使用eureka服务中的名称调用

　　服务的名称：

spring:
  application:
    name: cloud-payment-service　　

　　　　8001，8002端口

　　客户端调用

    @Autowired
    private RestTemplate restTemplate;

    private String url = "http://CLOUD-PAYMENT-SERVICE";　　//写到配置文件中

    @RequestMapping("/insert")
    public BaseResult insert(Payment payment) {

        restTemplate.postForEntity("url" + "/payment/insert", payment, BaseResult.class);

        return sendSuccess();
    }

　　备注：注册bean,开启负载

@Component
@Configuration
public class AppConfiguration {
    
    @LoadBalanced   // 负载均衡
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}
