单独使用ribbon

建立两个服务端，分别是8080和8081

建立客户端

 代码

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);}}
}
