springboot中如何使用minio存儲容器

更新時間：2022年02月03日 11:08:38 作者：頭發(fā)與技術(shù)雙全

大家好，本篇文章主要講的是springboot中如何使用minio存儲容器，感興趣的同學趕快來看一看吧，對你有幫助的話記得收藏一下

docker運行

docker run
  -p 9000:9000   
  -p 9001:9001   
  -v /mydata/minio/data:/data  
  minio/minio server /data --console-address ":9001

java導包

最好是這個版本，其他版本嘗試過都出bug了

		<dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>8.2.1</version>
        </dependency>

配置文件

spring:
  # 上傳文件大小設置
  servlet:
    multipart:
      enabled: true
      max-file-size: 50MB
minio:
  endpoint: xxx:9000
  accesskey: xxx
  secretkey: xxx
  bucketName: xxx

操作

1、編寫一個屬性文件

@Data
@Component
@ConfigurationProperties(prefix = "minio") // 從配置文件的前綴拿
public class MinioProperties {

    private String endpoint;
    private String accessKey;
    private String secretKey;
}

2、編寫一個minioClient

@Configuration
public class MinioConfig {

    @Resource
    private MinioProperties minioProperties;

    @Bean
    public MinioClient minioClient() {
        System.out.println(minioProperties.getAccessKey());
        System.out.println(minioProperties.getSecretKey());
        MinioClient minioClient = MinioClient.builder()
                .endpoint(minioProperties.getEndpoint())
                .credentials(minioProperties.getAccessKey(), minioProperties.getSecretKey())
                .build();
        return minioClient;
    }
}

3、上傳文件Api

public class MinioServiceImpl implements MinioService {

    @Value("${minio.bucketName}")
    private String bucketName;
    @Value("${minio.endpoint}")
    private String endPoint;

    @Resource
    private MinioClient minioClient;

    @Override
    public List<String> uploadFile(MultipartFile[] file) throws ServerException, InsufficientDataException, ErrorResponseException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {
        if (file == null || file.length == 0) {
            throw new APIException(ResultCode.PARAM_IS_BLANK);
        }
        List<String> fileUrlList = new ArrayList<>(file.length);
        String url = "";
        for (MultipartFile multipartFile : file) {
            // 1.獲取文件名
            String originalFilename = multipartFile.getOriginalFilename();
            // 2.截取后綴名
            String imgSuffix = originalFilename.substring(originalFilename.lastIndexOf("."));
            // 3.生成唯一名
            String newFileName = UUID.randomUUID().toString() + imgSuffix;
            // 4.日期目錄
            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
            String dataPath = dateFormat.format(new Date());
            // 5.合成路徑
            String finalFileName = dataPath + "/" + newFileName;
            // 別忘了bucketName
            url = endPoint + "/" + bucketName + "/" + finalFileName;
            try {
                // 文件上傳
                InputStream in = multipartFile.getInputStream();
                minioClient.putObject(PutObjectArgs.builder().bucket(bucketName).object(finalFileName).stream(
                        in, multipartFile.getSize(), -1)
                        .contentType(multipartFile.getContentType())
                        .build());
                in.close();
                fileUrlList.add(url);
            } catch (IOException e) {
                throw new APIException(ResultCode.COMMON_FAIL);
            }
        }
        return fileUrlList;
    }
}
