ribbon做请求分发负载均衡

ribbon

配置:

server.port=9999
spring.application.name=ribbon-consumer
#stores.ribbon.listOfServers=localhost:8082,localhost:8081
eureka.client.service-url.defaultZone=http://localhost:8888/eureka,http://localhost:8889/eureka

　　启动类

@EnableDiscoveryClient
@SpringBootApplication
public class EurekaRibbonRibbon1Application {
@Bean
@LoadBalanced
	RestTemplate restTemplate(){
	return new RestTemplate();//面向服务调用

}

	public static void main(String[] args) {
		SpringApplication.run(EurekaRibbonRibbon1Application.class, args);
	}
}

　　controller

@RestController
public class ConsumerController {
    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("/consumer")
    public String helloConsumer() {
//        ServiceInstance serviceInstance=loadBalancerClient.choose("stores");
//        URI uri=URI.create(String.format("http://%s:%s",serviceInstance.getHost(),serviceInstance.getPort()));
//
//            return uri.toString();
        return restTemplate.getForEntity("http://HELLO-SERVICE:hello", String.class).getBody();
    }
}

　　访问http://localhost:9999/consumer

发现 显示本service的端口是8082or8081 说明成功 默认是轮询可以自己设置随机等其他配置
