Java资源组

更新时间:

本文介绍如何配置存储空间(Bucket)所属资源组以及获取Bucket资源组ID。

注意事项

  • 本文以华东1(杭州)外网Endpoint为例。如果您希望通过与OSS同地域的其他阿里云产品访问OSS,请使用内网Endpoint。关于OSS支持的Region与Endpoint的对应关系,请参见访问域名和数据中心

  • 本文以从环境变量读取访问凭证为例。如何配置访问凭证,请参见配置访问凭证

  • 本文以OSS域名新建OSSClient为例。如果您希望通过自定义域名、STS等方式新建OSSClient,请参见新建OSSClient

  • 要配置Bucket所属资源组,您必须拥有oss:PutBucketResourceGroup权限。要获取Bucket资源组ID,您必须拥有oss:GetBucketResourceGroup权限。具体操作,请参见为RAM用户授权自定义的权限策略

配置Bucket所属资源组

重要

配置Bucket所属资源组时,如果未指定资源组ID,则Bucket归属于默认资源组。如果您需要将Bucket加入指定资源组,请确保已创建资源组。具体操作,请参见创建资源组

以下代码用于配置examplebucket所属资源组。

import com.aliyun.oss.*;
import com.aliyun.oss.common.auth.*;
import com.aliyun.oss.model.SetBucketResourceGroupRequest;

public class Demo {
    public static void main(String[] args) throws Throwable {
        // Endpoint以华东1(杭州)为例,其它Region请按实际情况填写。
        String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
        // 从环境变量中获取访问凭证。运行本代码示例之前,请确保已设置环境变量OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。
        EnvironmentVariableCredentialsProvider credentialsProvider = CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();
        // 填写Bucket名称,例如examplebucket。
        String bucketName = "examplebucket";
        // 填写资源组ID。如果未填写资源组ID,则Bucket归属于默认资源组。
        String rgId = "rg-aekz****";

        // 创建OSSClient实例。
        OSS ossClient = new OSSClientBuilder().build(endpoint, credentialsProvider);

        try {
            // 创建setBucketResourceGroupRequest对象。
            SetBucketResourceGroupRequest setBucketResourceGroupRequest = new SetBucketResourceGroupRequest(bucketName,rgId);
            // 配置Bucket所属资源组。
            ossClient.setBucketResourceGroup(setBucketResourceGroupRequest);
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
}

获取Bucket资源组ID

以下代码用于获取examplebucket的资源组ID。

import com.aliyun.oss.*;
import com.aliyun.oss.common.auth.*;
import com.aliyun.oss.model.GetBucketResourceGroupResult;

public class Demo {
    public static void main(String[] args) throws Throwable {
        // Endpoint以华东1(杭州)为例,其它Region请按实际情况填写。
        String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
        // 从环境变量中获取访问凭证。运行本代码示例之前,请确保已设置环境变量OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。
        EnvironmentVariableCredentialsProvider credentialsProvider = CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();
        // 填写Bucket名称,例如examplebucket。
        String bucketName = "examplebucket";

        // 创建OSSClient实例。
        OSS ossClient = new OSSClientBuilder().build(endpoint, credentialsProvider);

        try {
            // 创建getBucketResourceGroupResult对象。
            GetBucketResourceGroupResult getBucketResourceGroupResult = ossClient.getBucketResourceGroup(bucketName);
            // 获取Bucket的资源组ID。
            String rgId = getBucketResourceGroupResult.getResourceGroupId();
            System.out.println(rgId);
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
}
