资源编排Java SDK使用示例 -

本文为您介绍资源编排服务ROS（Resource Orchestration Service）的Java SDK安装方法和示例代码。以查询可用地域列表、创建资源栈、查询资源栈、删除资源栈等操作为例，帮助您快速掌握资源编排接口的使用方法。

安装Java SDK

下载及安装Java SDK。
说明
- Java SDK的下载和使用说明，请参见SDK概览。
- 建议您使用JRE 1.8及以上版本。

在pom.xml中，添加依赖包。

初始化SDK。

导入相关的软件包。

import com.aliyun.tea.*;
import com.aliyun.ros20190910.*;
import com.aliyun.ros20190910.models.*;
import com.aliyun.teaopenapi.*;
import com.aliyun.teaopenapi.models.*;
import com.aliyun.darabonba.env.*;
import com.aliyun.credentials.*;
import java.util.*;

初始化SDK客户端对象。

public static com.aliyun.ros20190910.Client createClient() throws Exception {
        // 使用默认凭证初始化Credentials Client
        com.aliyun.credentials.Client credentialClient = new com.aliyun.credentials.Client();
        Config config = new Config()
                // 配置云产品服务接入地址（endpoint）
                .setEndpoint("ros.aliyuncs.com")
                // 使用Credential配置凭证
                .setCredential(credentialClient);
        return new com.aliyun.ros20190910.Client(config);
    }

示例

查询可用地域列表示例

通过调用DescribeRegions接口查询可用地域列表。关于DescribeRegions接口的详情，请参见DescribeRegions。

public static void describeRegions(Client client) throws Exception {
        DescribeRegionsRequest describeRegionsRequest = new DescribeRegionsRequest();
        // 复制代码运行后，请自行打印API的返回值。
        DescribeRegionsResponse resp = client.describeRegions(describeRegionsRequest);
    }

创建资源栈示例

通过调用CreateStack接口创建资源栈。关于CreateStack接口的详情，请参见CreateStack。

在本示例中，指定了以下参数：

regionId：资源栈所属的地域ID。
stackName：资源栈名称。同一阿里云账号中资源栈名称不能重复。
timeoutInMinutes：创建资源栈的超时时间，单位为分钟。如果在指定时间内不能完成创建，则资源栈创建失败。
templateBody：模板的主体结构。
parameters：创建的资源栈所需要的参数。需要同时指定ParameterKey和ParameterValue。

参数设置的实例代码如下所示。

String stackName = "MyStack";
Long timeoutInMinutes = 40L;
String templateBody = "{\n" +
                      "  \"ROSTemplateFormatVersion\": \"2015-09-01\",\n" +
                      "  \"Parameters\": {\n" +
                      "    \"VpcName\": {\n" +
                      "      \"Type\": \"String\",\n" +
                      "      \"Description\": \"Vpc Name\",\n" +
                      "      \"Label\": \"Vpc Name\"\n" +
                      "    },\n" +
                      "    \"CidrBlock\": {\n" +
                      "      \"Type\": \"String\",\n" +
                      "      \"Description\": \"Vpc CidrBlock\",\n" +
                      "      \"Label\": \"Vpc CidrBlock\"\n" +
                      "    }\n" +
                      "  },\n" +
                      "  \"Resources\": {\n" +
                      "    \"Vpc\": {\n" +
                      "      \"Type\": \"ALIYUN::ECS::VPC\",\n" +
                      "      \"Properties\": {\n" +
                      "        \"CidrBlock\": {\n" +
                      "          \"Ref\": \"CidrBlock\"\n" +
                      "        },\n" +
                      "        \"VpcName\": {\n" +
                      "          \"Ref\": \"VpcName\"\n" +
                      "        }\n" +
                      "      }\n" +
                      "    }\n" +
                      "  }\n" +
                      "}";
CreateStackRequest.CreateStackRequestParameters parameters0 = new CreateStackRequest.CreateStackRequestParameters()
                .setParameterKey("VpcName")
                .setParameterValue("TestVpc");
CreateStackRequest.CreateStackRequestParameters parameters1 = new CreateStackRequest.CreateStackRequestParameters()
                .setParameterKey("CidrBlock")
                .setParameterValue("192.168.0.0/16");

List parameters = java.util.Arrays.asList(parameters0, parameters1);

参数设置的示例代码如下所示。

public static void createStack(Client client, String regionId, String stackName, String templateBody, Long timeoutInMinutes, List parameters) throws Exception {
    CreateStackRequest createStackRequest = new CreateStackRequest()
            .setTemplateBody(templateBody)
            .setStackName(stackName)
            .setRegionId(regionId)
            .setTimeoutInMinutes(timeoutInMinutes)
            .setParameters(parameters);
     // 复制代码运行后，请自行打印API的返回值。
     CreateStackResponse resp = client.createStack(createStackRequest);
     com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(resp)));
}

查询资源栈示例
通过调用GetStack接口查询资源栈信息。关于GetStack接口的详情，请参见GetStack。
在本示例中，指定了以下参数：
- stackId：资源栈ID。
- regionId：资源栈所属的地域ID。
参数设置的示例代码如下：

public static void getStack(Client client, String stackId, String regionId) throws Exception {        
    GetStackRequest getStackRequest = new GetStackRequest()            
        .setStackId(stackId)            
        .setRegionId(regionId);    
        // 复制代码运行后，请自行打印API的返回值。    
    GetStackResponse resp = client.getStack(getStackRequest);    
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(resp)));
}

删除资源栈示例
通过调用DeleteStack接口删除资源栈。关于DeleteStack接口的详情，请参见DeleteStack。
在本示例中，指定了以下参数：
- regionId：资源栈所属的地域ID。
- stackId：资源栈ID。
参数设置的示例代码如下所示。

public static void deleteStack(Client client, String stackId, String regionId) throws Exception {    
    DeleteStackRequest deleteStackRequest = new DeleteStackRequest()
                .setStackId(stackId)
                .setRegionId(regionId);
    // 复制代码运行后，请自行打印API的返回值。
    DeleteStackResponse resp = client.deleteStack(deleteStackRequest);
    com.aliyun.teaconsole.Client.log(com.aliyun.teautil.Common.toJSONString(TeaModel.buildMap(resp)));
}

完整示例

以下为查询可用地域列表、创建资源栈、查询资源栈和删除资源栈的完整操作示例。

说明

调用接口前，需配置环境变量，通过环境变量读取访问凭证。更多信息，请参见配置访问凭证。

AccessKey ID和AccessKey Secret的环境变量名：ALIBABA_CLOUD_ACCESS_KEY_ID、ALIBABA_CLOUD_ACCESS_KEY_SECRET。
