DiscoveryClient 与@EnableEurekaServer

DiscoveryClient用法

discoveryClient接口 可以获取注册中心上的实例信息。

@EnableDiscoveryClient 开启其他注册中心 比如consul、zookeeper

@SpringBootApplication
@EnableDiscoveryClient
public class AppMember {
	public static void main(String[] args) {
		SpringApplication.run(AppMember.class, args);
	}
}

获取注册中心上信息

@RequestMapping("/getServiceUrl")
	public List<String> getServiceUrl() {
		List<ServiceInstance> list = discoveryClient.getInstances("zk-member");
		List<String> services = new ArrayList<>();
		for (ServiceInstance serviceInstance : list) {
			if (serviceInstance != null) {
				services.add(serviceInstance.getUri().toString());
			}
		}
		return services;
	}

@EnableDiscoveryClient 与@EnableEurekaClient区别

1，@EnableDiscoveryClient注解是基于spring-cloud-commons依赖，并且在classpath中实现； 适合于consul、zookeeper注册中心

2，@EnableEurekaClient注解是基于spring-cloud-netflix依赖，只能为eureka作用；
