Java SDK使用示例 - 资源编排

本文为您介绍如何使用资源编排服务ROS（Resource Orchestration Service）的Java SDK来创建和管理资源栈。

背景信息

您除了可以在ROS控制台创建资源栈，还可以使用API代码来创建和管理资源栈。

准备工作

下载及安装Java SDK。

说明建议您使用JRE 1.8及以上版本。

在pom.xml中，添加aliyun-java-sdk-core及其它依赖包。

<dependencies>
    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-java-sdk-core</artifactId>
        <version>4.4.0</version>
    </dependency>
    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-java-sdk-ros</artifactId>
        <version>3.2.0</version>
    </dependency>
</dependencies>

初始化SDK。

导入相关的包。

import java.util.ArrayList;
import java.util.List;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.FormatType;
import com.aliyuncs.http.HttpResponse;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.ros.model.v20190910.CreateStackRequest;
import com.aliyuncs.ros.model.v20190910.DeleteStackRequest;
import com.aliyuncs.ros.model.v20190910.DescribeRegionsRequest;
import com.aliyuncs.ros.model.v20190910.GetStackRequest;

初始化SDK客户端对象。

private static String ACCESSKEYID = "<yourAccessKeyId>";
private static String SECRET = "<yourAccessKeySecrect>";
private static String REGIONID = "<yourRegionId>";
private static DefaultAcsClient client = new DefaultAcsClient(DefaultProfile.getProfile(REGIONID, ACCESSKEYID, SECRET));
private static int connectTimeout = 10000;
private static int readTimeout = 10000;
private static Long timeoutInMinutes = 30L;

查询可用地域列表

您可以使用Java SDK查询可用地域列表。

public String describeRegion() {
    DescribeRegionsRequest request = new DescribeRegionsRequest();
    request.setConnectTimeout(connectTimeout);
    request.setReadTimeout(readTimeout);
    request.setAcceptFormat(FormatType.JSON);
    HttpResponse response = null;
    String responseContent = null;
    try {
        response = client.doAction(request);
        responseContent = response.getHttpContentString();
    } catch (ClientException e) {
        e.printStackTrace();
    }
    return responseContent;
}

创建资源栈

创建资源栈时，您必须指定以下参数：

StackName：将要创建的资源栈的名称。每个用户空间下的资源栈名称不能重复。
TimeoutInMinutes：资源栈创建时长，单位为分钟。如果在指定时间内不能完成创建，则超时失败。
TemplateBody：创建的资源栈使用的模板内容。
TemplateURL：模板主体的文件的位置。必须指定TemplateBody或TemplateURL，但不能同时指定两者。
Parameters：创建的资源栈所需的参数。需要在模板中定义Key。

String stackName = "MyStack";
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" +
        "}";
List<CreateStackRequest.Parameters> parameterss = new ArrayList<CreateStackRequest.Parameters>();
CreateStackRequest.Parameters cidrBlock = new CreateStackRequest.Parameters();
cidrBlock.setParameterKey("CidrBlock");
cidrBlock.setParameterValue("192.168.0.0/16");
CreateStackRequest.Parameters vpcName = new CreateStackRequest.Parameters();
vpcName.setParameterKey("VpcName");
vpcName.setParameterValue("TestVpc");
parameterss.add(cidrBlock);
parameterss.add(vpcName);

public String createStack(String stackName, String templateBody, List<CreateStackRequest.Parameters> parameterss) {
    CreateStackRequest request = new CreateStackRequest();
    request.setConnectTimeout(connectTimeout);
    request.setReadTimeout(readTimeout);
    request.setTimeoutInMinutes(timeoutInMinutes);
    request.setStackName(stackName);
    // 若模板较大，建议使用TemplateURL参数，避免URL过长，调用失败。
    // 您也可以继承CreateStackRequest类，通过调用putBodyParameter（protected方法）自行实现setTemplateBody方法。
    // request.putBodyParameter("TemplateBody", templateBody)
    request.setTemplateBody(templateBody);
    request.setParameterss(parameterss);
    HttpResponse response = null;
    String responseContent = null;
    try {
        response = client.doAction(request);
        responseContent = response.getHttpContentString();
    } catch (ClientException e) {
        e.printStackTrace();
    }
    return responseContent;
}

查询资源栈

输入目标资源栈的ID。

public String getStack(String stackId) {
    GetStackRequest request = new GetStackRequest();
    request.setConnectTimeout(connectTimeout);
    request.setReadTimeout(readTimeout);
    request.setStackId(stackId);
    request.setAcceptFormat(FormatType.JSON);
    HttpResponse response = null;
    String responseContent = null;
    try {
        response = client.doAction(request);
        responseContent = response.getHttpContentString();
    } catch (ClientException e) {
        e.printStackTrace();
    }
    return responseContent;
}

删除资源栈

输入目标资源栈的ID。

public String deleteStack(String stackId) {
    DeleteStackRequest request = new DeleteStackRequest();
    request.setConnectTimeout(connectTimeout);
    request.setReadTimeout(readTimeout);
    request.setStackId(stackId);
    request.setAcceptFormat(FormatType.JSON);
    HttpResponse response = null;
    String responseContent = null;
    try {
        response = client.doAction(request);
        responseContent = response.getHttpContentString();
    } catch (ClientException e) {
        e.printStackTrace();
    }
    return responseContent;
}
