SpringCloud-LoadBalancerClient

源码地址

创建一个SpringBoot项目

取名为：eureka-consumer

添加相关依赖：

    
        org.springframework.cloud
        spring-cloud-starter-eureka
    
    
        org.springframework.boot
        spring-boot-starter-web
    
    
        org.springframework.boot
        spring-boot-starter-actuator
    

配置application.properties

spring.application.name=eureka-consumer
server.port=2101
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/

在启动类初始化RestTemplate并添加@EnableDiscoveryClient

创建一个controller用来消费eureka-client

@RestController
public class ZxController {
    @Resource
    LoadBalancerClient loadBalancerClient;
    @Autowired
    RestTemplate restTemplate;

    @GetMapping("/consumer")
    public String zx() {
        ServiceInstance serviceInstance = loadBalancerClient.choose("eureka-client");
        String url = "http://" + serviceInstance.getHost() + ":" + serviceInstance.getPort() + "/dc";
        System.out.println(url);
        return restTemplate.getForObject(url, String.class);
    }
}

然后依次启动

访问http://localhost:2101/consumer
