阿里云EAIS Java SDK让您不用复杂编程即可访问阿里云弹性加速计算实例EAIS服务。本文介绍如何使用EAIS Java SDK以及阿里云核心库。
安装Java SDK
您可以使用以下两种方式：
-
（推荐）使用Maven坐标来使用Java SDK，您只需在
Maven pom.xml中添加以下依赖项即可。<dependencies> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <optional>true</optional> <version>4.5.16</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.5</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-eais</artifactId> <version>2.0.1</version> </dependency> </dependencies> -
访问Java SDK的Maven地址：Maven Central Repository Search，自行下载aliyun-java-sdk-eais。
Demo示例
-
创建一个EAIS实例。
import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.exceptions.ServerException; import com.aliyuncs.profile.DefaultProfile; import com.google.gson.Gson; import java.util.*; import com.aliyuncs.eais.model.v20190624.*; public class CreateEai { public static void main(String[] args) { //创建DefaultAcsClient实例并初始化。 DefaultProfile profile = DefaultProfile.getProfile("cn-beijing", "<accessKeyId>", "<accessSecret>"); IAcsClient client = new DefaultAcsClient(profile); //创建API请求并设置参数。 CreateEaiRequest request = new CreateEaiRequest(); request.setRegionId("cn-beijing"); request.setInstanceType("eais.ei-a6.2xlarge"); try { //发起请求并处理应答或异常。 CreateEaiResponse response = client.getAcsResponse(request); System.out.println(new Gson().toJson(response)); } catch (ServerException e) { e.printStackTrace(); } catch (ClientException e) { System.out.println("ErrCode:" + e.getErrCode()); System.out.println("ErrMsg:" + e.getErrMsg()); System.out.println("RequestId:" + e.getRequestId()); } } }返回如下数据。
{ "requestId": "FDFECE42-CE82-4D3D-87CC-DD2C4DB6DBE7", "elasticAcceleratedInstanceId": "eais-bjdzlzro*********" }

绑定指定EAIS实例。
import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.exceptions.ServerException; import com.aliyuncs.profile.DefaultProfile; import com.google.gson.Gson; import java.util.*; import com.aliyuncs.eais.model.v20190624.*; public class AttachEai { public static void main(String[] args) { //创建DefaultAcsClient实例并初始化。 DefaultProfile profile = DefaultProfile.getProfile("cn-beijing", "<accessKeyId>", "<accessSecret>"); IAcsClient client = new DefaultAcsClient(profile); //创建API请求并设置参数。 AttachEaiRequest request = new AttachEaiRequest(); request.setRegionId("cn-beijing"); request.setElasticAcceleratedInstanceId("eais-bjdzlzro*********"); request.setClientInstanceId("i-2zeaiw86f*********"); try { //发起请求并处理应答或异常。 AttachEaiResponse response = client.getAcsResponse(request); System.out.println(new Gson().toJson(response)); } catch (ServerException e) { e.printStackTrace(); } catch (ClientException e) { System.out.println("ErrCode:" + e.getErrCode()); System.out.println("ErrMsg:" + e.getErrMsg()); System.out.println("RequestId:" + e.getRequestId()); } } }返回如下数据。
{ "requestId": "D175D01C-64C4-4125-9B05-D6212159C5AF", "elasticAcceleratedInstanceId": "eais-bjdzlzro*********", "clientInstanceId": "i-2zeaiw86f*********" }
