欢迎使用阿里云开发者工具套件（Alibaba Cloud SDK for Java），此为OpenApi的SDK文档说明。Alibaba Cloud SDK for Java让您不用复杂编程即可对云数据库HBase实例进行管理，包括创建、升级、删除实例、白名单、标签管理等，详情查看《API参考》，注：其有别于访问HBase实例的sdk。本教程介绍如何安装并开始使用Alibaba Cloud SDK for Java。

1、创建AccessKey

在线调试和生成SDK示例

OpenAPI Explorer提供在线调用云产品API、动态生成 SDK示例代码和快速检索接口等功能，能显著降低使用API的难度，推荐您使用，进入页面后，选择HBase产品，提供了接口列表，且包含了各个语言的调试demo，供大家参考。

1、安装下载Alibaba Cloud SDK for Java

注意：通过maven引用sdk包时，请下载最新的版本。

2、示例demo

1）设置环境参数

DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou",
                "LTAI4FnvzUftE**********", "PxPzgelK1XCkWBXW***********");
		// 以下非必选项，可默认
        DefaultProfile.addEndpoint(
                "cn-hangzhou",    // 地域ID
                "hbase",    // 产品编码
                "hbase.aliyuncs.com"    // 接入地址，即域名
        );

2）初始化客户端

IAcsClient client = new DefaultAcsClient(profile);

3）构造请求对象

DescribeInstanceRequest request = new DescribeInstanceRequest();
        request.setClusterId("ap-*****************");

4）请求调用

DescribeInstanceResponse response;
        try {
            response = client.getAcsResponse(request);
            System.out.println(new Gson().toJson(response));
        } catch (ClientException e) {
            e.printStackTrace();
        }

参考示例

DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou",
                "ak******************", "akSecret********************");
        DefaultProfile.addEndpoint(
                "cn-hangzhou",    // 地域ID
                "hbase",    // 产品编码
                "hbase.aliyuncs.com"    // 接入地址，即域名
        );
        IAcsClient client = new DefaultAcsClient(profile);
        DescribeInstanceRequest request = new DescribeInstanceRequest();
        request.setClusterId("ap-******************");
        DescribeInstanceResponse response;
        try {
            response = client.getAcsResponse(request);
            System.out.println(new Gson().toJson(response));
        } catch (ClientException e) {
            e.printStackTrace();
        }
