本示例介绍如何使用Alibaba Cloud SDK for Java调用DescribeInstanceAutoRenewAttribute接口查询预付费实例自动续费状态。

前提条件

在使用本教程之前,请确保已完成以下操作:

  • 使用Alibaba Cloud SDK for Java,您需要一个阿里云账号和访问密钥(AccessKey)。 请在阿里云控制台中的AccessKey管理页面
  • 确保您已经安装了Alibaba Cloud SDK for Java,准确的SDK版本号,请参见 阿里云开发工具包(SDK)
    <dependencies>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-core --&gt;     <dependency&gt;         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-core</artifactId>         <version>4.4.3</version>     </dependency>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-ecs-->     <dependency>         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-ecs</artifactId>         <version>4.17.4</version>     </dependency>     <!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->     <dependency>         <groupId>com.alibaba</groupId>         <artifactId>fastjson</artifactId>         <version>1.2.61</version>     </dependency> </dependencies>

示例代码

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.ecs.model.v20140526.DescribeInstanceAutoRenewAttributeRequest; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.exceptions.ServerException; import com.aliyuncs.http.FormatType; import com.aliyuncs.profile.DefaultProfile; import com.aliyuncs.profile.IClientProfile; import com.alibaba.fastjson.JSON;  public class ECSOperate {     private static final String ACCESS_KEY = "<your-access-key>";     private static final String ACCESS_SECRET = "<your-access-key_Secret>";     private static final String REGION_ID = "<your-region-Id>";     private static IAcsClient client = null;      static {         //创建profile         IClientProfile profile = DefaultProfile.getProfile(REGION_ID, ACCESS_KEY, ACCESS_SECRET);         //创建client         client = new DefaultAcsClient(profile);     }      public static String describeInstanceAutoRenewAttribute(FormatType formatType) {         //构造请求         DescribeInstanceAutoRenewAttributeRequest request = new DescribeInstanceAutoRenewAttributeRequest();         request.setInstanceId("<Instance-Id>");         request.setAcceptFormat(formatType);         try {             //获取返回对象             return JSON.toJSONString(client.getAcsResponse(request));         } catch (ServerException e) {             System.out.println("服务器异常 " + e);             e.printStackTrace();             return null;         } catch (ClientException e) {             System.out.println("参数配置异常:" + e);             e.printStackTrace();             return null;         }     }     public static void main(String[] args) {     System.out.println(describeInstanceAutoRenewAttribute(FormatType.JSON));     } }
