建立两个服务端，分别是8080和8081

package org.example.ribbon;

import com.netflix.client.ClientFactory;
import com.netflix.client.http.HttpRequest;
import com.netflix.client.http.HttpResponse;
import com.netflix.config.ConfigurationManager;
import com.netflix.niws.client.http.RestClient;

public class TestRestClient {

	public static void main(String[] args) throws Exception {
		// 设置请求的服务器
		ConfigurationManager.getConfigInstance().setProperty(
				"my-client.ribbon.listOfServers",
				"localhost:8080,localhost:8081");
		// 获取REST请求客户端
		RestClient client = (RestClient) ClientFactory
				.getNamedClient("my-client");
		// 创建请求实例
		HttpRequest request = HttpRequest.newBuilder().uri("/users/123").build();
		// 发 送10次请求到服务器中
		for (int i = 0; i < 6; i++) {
			HttpResponse response = client.executeWithLoadBalancer(request);
			String result = response.getEntity(String.class);
			System.out.println(result);
		}
	}
}
