创建和删除SLB实例

前提条件

代码示例

本文操作示例主要以代码形式体现，具体代码如下：

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.slb.model.v20140515.CreateLoadBalancerRequest;
import com.aliyuncs.slb.model.v20140515.CreateLoadBalancerResponse;
import com.aliyuncs.slb.model.v20140515.DeleteLoadBalancerRequest;
import com.aliyuncs.slb.model.v20140515.DeleteLoadBalancerResponse;
import com.google.gson.Gson;

/**
 * 使用Java SDK创建和删除负载均衡实例使用示例

public class CreateAndDeleteSlbDemo {


    /**

     *

     */
    private CreateLoadBalancerResponse createLoadBalancer(CreateLoadBalancerRequest request, IAcsClient client) {

        // 初始化返回对象
        CreateLoadBalancerResponse response = null;
        try {
            // 调用SDK发送请求
            response = client.getAcsResponse(request);
        } catch (ClientException e) {
            e.printStackTrace();
            // 发生调用错误，抛出运行时异常
            throw new RuntimeException();
        }
        return response;
    }

    private DeleteLoadBalancerResponse deleteLoadBalancer(DeleteLoadBalancerRequest request, IAcsClient client) {
        // 初始化返回对象

        try {
            // 调用SDK发送请求

        } catch (ClientException e) {
            e.printStackTrace();

            throw new RuntimeException();
        }
        return response;
    }

    public static void main(String[] args) {

        // 设置鉴权参数，初始化客户端
        DefaultProfile profile = DefaultProfile.getProfile(
                "cn-zhangjiakou",// 地域ID
                "your-access-key-id",// 您的AccessKey ID
                "your-access-key-secret");// 您的AccessKey Secret
        IAcsClient client = new DefaultAcsClient(profile);

        CreateAndDeleteSlbDemo createAndDeleteSlbDemo = new CreateAndDeleteSlbDemo();

        // 初始化创建SLB实例方法入参对象
        CreateLoadBalancerRequest createLoadBalancerRequest = new CreateLoadBalancerRequest();
        // 设置新建SLB实例的主可用区为cn-zhangjiakou-a
        createLoadBalancerRequest.setMasterZoneId("cn-zhangjiakou-a");
        // 设置新建SLB实例的备可用区为cn-zhangjiakou-b
        createLoadBalancerRequest.setSlaveZoneId("cn-zhangjiakou-b");
        // 设置新建SLB实例的名称为SLB1
        createLoadBalancerRequest.setLoadBalancerName("SLB1");
        // 设置新建SLB实例的计费类型为按量计费
        createLoadBalancerRequest.setPayType("PayOnDemand");
        // 设置新建SLB实例的规格为slb.s1.small
        createLoadBalancerRequest.setLoadBalancerSpec("slb.s1.small");
        // 设置监听的带宽峰值
        createLoadBalancerRequest.setBandwidth(1);

        // 调用创建SLB实例方法，获取新实例参数
        CreateLoadBalancerResponse createLoadBalancerResponse = createAndDeleteSlbDemo.createLoadBalancer(createLoadBalancerRequest, client);
        System.out.println("-------------------------------createLoadBalancer-------------------------------");
        System.out.println(new Gson().toJson(createLoadBalancerResponse));

        // 初始化删除SLB实例方法入参对象
        DeleteLoadBalancerRequest deleteLoadBalancerRequest = new DeleteLoadBalancerRequest();
        // 设置要删除的SLB实例ID，此处使用刚才创建的实例ID
        deleteLoadBalancerRequest.setLoadBalancerId(createLoadBalancerResponse.getLoadBalancerId());
        // 调用删除SLB实例方法
        DeleteLoadBalancerResponse deleteLoadBalancerResponse = createAndDeleteSlbDemo.deleteLoadBalancer(deleteLoadBalancerRequest, client);
        System.out.println("-------------------------------deleteLoadBalancer-------------------------------");
        System.out.println(new Gson().toJson(deleteLoadBalancerResponse));
    }
}

运行结果
