一个完整的上传文件示例

需要可以看minio 我的上个文章有介绍

1、加入如下依赖

io.minio minio 8.5.2

yaml配置

minio:endpointUrl: http://127.0.0.1:9000accessKey: minioadminsecreKey: minioadminbucketName: spzx-bucket

MinioProperties配置类用来通过前缀加载yaml

@Data
@Component
@ConfigurationProperties(prefix = "spzx.minio")
public class MinioProperties {private String endpointUrl;private String accessKey;private String secreKey;private String bucketName;
}

controller

@Resource
private FileUploadService fileUploadService;@PostMapping("/fileUpload")
public Result<String> fileUploadService (@RequestParam("file") MultipartFile file) throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {String url =fileUploadService.uploadFile(file);return Result.build(url, ResultCodeEnum.SUCCESS);
}

实现类

@Resource
private MinioProperties minioProperties ;
@Override
public String uploadFile(MultipartFile multipartFile) throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {try {// 创建一个Minio的客户端对象MinioClient minioClient = MinioClient.builder().endpoint(minioProperties.getEndpointUrl()).credentials(minioProperties.getAccessKey(), minioProperties.getSecreKey()).build();// 判断桶是否存在boolean found = minioClient.bucketExists(BucketExistsArgs.builder().bucket(minioProperties.getBucketName()).build());if (!found) {       // 如果不存在，那么此时就创建一个新的桶minioClient.makeBucket(MakeBucketArgs.builder().bucket(minioProperties.getBucketName()).build());} else {  // 如果存在打印信息System.out.println("Bucket 'spzx-bucket' already exists.");}// 设置存储对象名称String dateDir = DateUtil.format(new Date(), "yyyyMMdd");String uuid = UUID.randomUUID().toString().replace("-", "");//20230801/443e1e772bef482c95be28704bec58a901.jpgString fileName = dateDir+"/"+uuid+multipartFile.getOriginalFilename();System.out.println(fileName);PutObjectArgs putObjectArgs = PutObjectArgs.builder().bucket(minioProperties.getBucketName()).stream(multipartFile.getInputStream(), multipartFile.getSize(), -1).object(fileName).build();minioClient.putObject(putObjectArgs) ;return minioProperties.getEndpointUrl() + "/" + minioProperties.getBucketName() + "/" + fileName ;} catch (Exception e) {throw new RuntimeException(e);}
}
