Springboot定义阿里云oss工具类
文章目录
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.com
access-key-id: you_key_id
access-key-secret: you_key_secret
bucket-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
@ConditionalOnMissingBean
public 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/ObjectName
StringBuilder 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();
}
}
