本教程详细介绍如何使用Alibaba Cloud SDK for Java查询DRDS实例详情。

前提条件

在使用本教程前,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管理页面上创建和查看您的AccessKey。
  • 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)

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.alibaba.sdk.polardb.RDScfg;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.drds.model.v20190123.DescribeDrdsDBsRequest;
import com.aliyuncs.drds.model.v20190123.DescribeDrdsDBsResponse;
import com.aliyuncs.drds.model.v20190123.DescribeDrdsInstanceRequest;
import com.aliyuncs.drds.model.v20190123.DescribeDrdsInstanceResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;

/**
 * DescribeDrdsDBs        查询数据库列表
 * DescribeDrdsInstance    查看DRDS实例详情
 */
public class demo{

    // drds实例ID
    private static String drdsInstanceId = "";

    public static void main(String[] args) {
        IAcsClient client = initialization();
        // 查询数据库列表
        DescribeDrdsDBsResponse describeDrdsDBsResponse = describeDrdsDBs(client);
        // 查看DRDS实例详情
        DescribeDrdsInstanceResponse describeDrdsInstanceResponse = describeDrdsInstance(client);
        // 处理业务逻辑
        System.out.println(new Gson().toJson(describeDrdsDBsResponse));
        System.out.println(new Gson().toJson(describeDrdsInstanceResponse));

    }

    /**
     * DescribeDrdsInstance    查看DRDS实例详情
     */
    private static DescribeDrdsInstanceResponse describeDrdsInstance(IAcsClient client) {
        DescribeDrdsInstanceRequest request = new DescribeDrdsInstanceRequest();
        request.setDrdsInstanceId(drdsInstanceId);
        try {
            DescribeDrdsInstanceResponse response = client.getAcsResponse(request);
            return response;
        } catch (ClientException e) {
            System.out.println("ErrCode:" + e.getErrCode());
            System.out.println("ErrMsg:" + e.getErrMsg());
            System.out.println("RequestId:" + e.getRequestId());
            throw new RuntimeException();
        }
    }

    /**
     * DescribeDrdsDBs        查询数据库列表
     */
    private static DescribeDrdsDBsResponse describeDrdsDBs(IAcsClient client) {
        DescribeDrdsDBsRequest request = new DescribeDrdsDBsRequest();
        // DRDS实例ID
        request.setDrdsInstanceId(drdsInstanceId);
        try {
            DescribeDrdsDBsResponse response = client.getAcsResponse(request);
            return response;
        } catch (ClientException e) {
            System.out.println("ErrCode:" + e.getErrCode());
            System.out.println("ErrMsg:" + e.getErrMsg());
            System.out.println("RequestId:" + e.getRequestId());
            throw new RuntimeException();
        }
    }

    /**
     * Initialization  初始化公共请求参数
     */
    private static IAcsClient initialization() {
        // 初始化请求参数
        DefaultProfile profile = DefaultProfile.getProfile(
                "<your-region-id>", // 您的可用区ID
                "<your-access-key-id>", // 您的AccessKey ID
                "<your-access-key-secret>"); // 您的AccessKey Secret
        return new DefaultAcsClient(profile);
    }
}

执行结果
