Java SpringBoot 集成 MinIO 资料

一、文档

1. 官方文档
2. CSDN项目示例
3. 解除Spring文件上传大小限制

二、个人实战

注意事项：

• 部署MinIO时会涉及到两个端口号，一个为endpoint的端口，一个为console的端口，注意不要弄混

  比如：

  • endpoint的端口为18893
  • console的端口为18894

• pom.xml

  <dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>7.0.2</version>
  </dependency>
  

• 配置文件

  minio:bucket: endpoint: access-key: secret-key: url: ${minio.endpoint}/${minio.bucket}/
  

• 配置实体类

  @Data
  @ConfigurationProperties(prefix = "minio")
  public class MinIOProperty {private String bucket;private String endpoint;private String access_key;private String secret_key;private String url;}
  

  @Configuration
  @EnableConfigurationProperties({MinIOProperty.class})
  public class ApplicationConfig {}
  

• DTO

  @Data
  @ApiModel(description = "文件的DTO")
  public class FileDTO {@ApiModelProperty(value = "上传文件原始名称")private String origin_file_name;@ApiModelProperty(value = "上传文件格式化后的名称")private String encode_file_name;@ApiModelProperty(value = "上传文件的地址")private String url;}
  

• Util

  @Service
  public class MinIOUtil {private final MinIOProperty minIOProperty;private final MinioClient minioClient;private final SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss_");public MinIOUtil(MinIOProperty minIOProperty) throws InvalidPortException, InvalidEndpointException {this.minIOProperty = minIOProperty;this.minioClient = new MinioClient(minIOProperty.getEndpoint(),minIOProperty.getAccess_key(),minIOProperty.getSecret_key());}public FileDTO upload(String path, MultipartFile multipartFile) throws Exception {// bucket 不存在，创建if (!minioClient.bucketExists(this.minIOProperty.getBucket())) {minioClient.makeBucket(this.minIOProperty.getBucket());}try (InputStream inputStream = multipartFile.getInputStream()) {// 上传文件的名称String fileName = multipartFile.getOriginalFilename();//格式化文件名称String encode_fileName = this.getNowString() + fileName;String objectName = path + "/" + encode_fileName;// PutObjectOptions，上传配置(文件大小，内存中文件分片大小)PutObjectOptions putObjectOptions = new PutObjectOptions(multipartFile.getSize(), PutObjectOptions.MIN_MULTIPART_SIZE);// 文件的ContentTypeputObjectOptions.setContentType(multipartFile.getContentType());minioClient.putObject(this.minIOProperty.getBucket(), objectName, inputStream, putObjectOptions);// 返回访问路径assert fileName != null;FileDTO fileDTO = new FileDTO();fileDTO.setOrigin_file_name(fileName);fileDTO.setEncode_file_name(encode_fileName);fileDTO.setUrl(this.minIOProperty.getUrl() + UriUtils.encode(objectName, StandardCharsets.UTF_8));return fileDTO;}}public void removeObject(String objectName) throws Exception {boolean flag = bucketExists(minIOProperty.getBucket());if (flag) {minioClient.removeObject(minIOProperty.getBucket(), objectName);}}public boolean bucketExists(String bucketName) throws Exception {return minioClient.bucketExists(bucketName);}public String getObjectNameFromUrl(String url) {return UriUtils.decode(url.replace(minIOProperty.getUrl(), ""), StandardCharsets.UTF_8);}private String getNowString() {Date date = new Date();return this.sdf.format(date);}}
  

• Controller

  @Api(tags = "MinIO文件上传模块")
  @RestController
  @CrossOrigin
  @RequestMapping("/minio")
  public class MinioController {private final MinIOUtil minIOUtil;private final CaseFileService caseFileService;public MinioController(MinIOUtil minIOUtil, CaseFileService caseFileService) {this.minIOUtil = minIOUtil;this.caseFileService = caseFileService;}@PostMapping("/upload")@ApiOperation(value = "上传文件")@ApiImplicitParams({@ApiImplicitParam(name = "file", value = "上传的文件", required = true)})public void upload(@RequestParam("file") MultipartFile multipartFile) throws Exception {FileDTO fileDTO = this.minIOUtil.upload("", multipartFile);}}
