springcloud==ribbon
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);
}
}
}
