Springboot定义阿里云oss工具类

Springboot定义阿里云oss工具类

---

1、定义OSS相关配置

首先，在 application.yml 文件中定义阿里云 OSS 的相关配置信息。这些配置包括 endpoint、access-key-id、access-key-secret 和 bucket-name。

alioss:endpoint: oss-cn-hangzhou.aliyuncs.comaccess-key-id: you_key_idaccess-key-secret: you_key_secretbucket-name: your_bucket_name

2、读取OSS配置

接下来，创建一个 AliOssProperties 类，用于读取 application.yml 中的配置。

@Component
@ConfigurationProperties(prefix = "oss.alioss")
@Data
public class AliOssProperties {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;}

3、生成OSS工具类对象

为了生成 OSS 工具类对象，我们需要创建一个配置类 OssConfiguration，并在其中定义一个 AliOssUtil 的 Bean。

/*** 配置类，用于创建AliOssUtil对象*/
@Configuration
@Slf4j
public class OssConfiguration {@Bean@ConditionalOnMissingBeanpublic AliOssUtil aliOssUtil(AliOssProperties aliOssProperties){log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);return new AliOssUtil(aliOssProperties.getEndpoint(),aliOssProperties.getAccessKeyId(),aliOssProperties.getAccessKeySecret(),aliOssProperties.getBucketName());}
}

4、定义使用工具类

最后，定义 AliOssUtil 工具类，实现文件上传功能。

@Data
@AllArgsConstructor
@Slf4j
public class AliOssUtil {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;/*** 文件上传** @param bytes* @param objectName* @return*/public String upload(byte[] bytes, String objectName) {// 创建OSSClient实例。OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);try {// 创建PutObject请求。ossClient.putObject(bucketName, objectName, new ByteArrayInputStream(bytes));} 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();}}//文件访问路径规则 https://BucketName.Endpoint/ObjectNameStringBuilder stringBuilder = new StringBuilder("https://");stringBuilder.append(bucketName).append(".").append(endpoint).append("/").append(objectName);log.info("文件上传到:{}", stringBuilder.toString());return stringBuilder.toString();}
}
