Java调用Oss JDk删除指定目录下的所有文件

1，引入依赖

<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>3.16.1</version>
</dependency>

2，方法

/**
	 * 删除指定前缀或目录下的多个文件
	 *
	 * @param prefix 删除目录
	 */
	public void deletePathFileList(String prefix) {
		OSS ossClient = null;
		try {
            //封装创建Oss实例
			CredentialsProvider credentialsProvider = new DefaultCredentialProvider(access_key, secret_key);
			ClientBuilderConfiguration clientBuilderConfiguration = new ClientBuilderConfiguration();
			clientBuilderConfiguration.setSignatureVersion(SignVersion.V4);
			ossClient = OSSClientBuilder.create().endpoint(endpoint).credentialsProvider(credentialsProvider).clientConfiguration(clientBuilderConfiguration).region(region).build();
            // 列举所有包含指定前缀的文件并删除。
			String nextMarker = null;
			ObjectListing objectListing;
			do {
				ListObjectsRequest listObjectsRequest = new ListObjectsRequest(bucket).withPrefix(prefix).withMarker(nextMarker);

				objectListing = ossClient.listObjects(listObjectsRequest);
				if (!objectListing.getObjectSummaries().isEmpty()) {
					List<String> keys = new ArrayList<>();
					for (OSSObjectSummary s : objectListing.getObjectSummaries()) {
						keys.add(s.getKey());
					}
					DeleteObjectsRequest deleteObjectsRequest = new DeleteObjectsRequest(bucket).withKeys(keys).withEncodingType("url");
					DeleteObjectsResult deleteObjectsResult = ossClient.deleteObjects(deleteObjectsRequest);
					List<String> deletedObjects = deleteObjectsResult.getDeletedObjects();
					for (String obj : deletedObjects) {
						String deleteObj = URLDecoder.decode(obj, "UTF-8");
						System.out.println(deleteObj);
					}
				}
				nextMarker = objectListing.getNextMarker();
			} while (objectListing.isTruncated());
		} catch (Exception e) {
			log.error("阿里云删除指定前缀或目录下的多个文件异常:{}", e.getMessage());
		} finally {
			if (ossClient != null) {
				ossClient.shutdown();
			}
		}
