SpringBoot 使用minio 分布式文件服务

SpringBoot 使用minio 分布式文件服务

依赖

<dependency>
	<groupId>io.miniogroupId>
	<artifactId>minioartifactId>
	<version>6.0.2version>
dependency>

<dependency>
    <groupId>org.projectlombokgroupId>
    <artifactId>lombokartifactId>
    <scope>providedscope>
dependency>

1、在application.yml中配置

# 文件系统
minio:
  url: http://127.0.0.1:9000
  access-key: xxxxxxxxx
  secret-key: xxxxxxxx
  bucket-name: zdrjy

2、注入配置到properties

@Data
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioProperties {
   /**
    * minio 服务地址 http://ip:port
    */
   private String url;
   /**
    * 用户名
    */
   private String accessKey;
   /**
    * 密码
    */
   private String secretKey;
    /**
    * 桶名称
    */
   private String bucketName;
}

3、初始化 MinioClient 自动注入到 spring 容器

@AllArgsConstructor
@EnableConfigurationProperties({MinioProperties.class})
public class MinioAutoConfiguration {
   private final MinioProperties properties;

   @Bean
   @ConditionalOnMissingBean(MinioTemplate.class)
   @ConditionalOnProperty(name = "minio.url")
   MinioClient minioClient() {
      return new MinioClient(
            properties.getUrl(),
            properties.getAccessKey(),
            properties.getSecretKey()
      );
   }
}

4、创建Service

@Slf4j
@Component
@AllArgsConstructor
public class MinioStorageService {
    
    private final MinioClient minioClient;
    private final MinioProperties minioProperties;
    
    /**
    * 上传文件
    */
    public String uploadFile(byte[] data, String filePath) {
        InputStream inputStream = new ByteArrayInputStream(data);
        String path;
        try {
            client.putObject(minioClient.getBucketName(), filePath, inputStream, inputStream.available(), getContextType(fileName));
            path = filePath;
        } catch (Exception e) {
            log.error("=====minio:"+e.getMessage());
        }
        return path;
    }
    
        
    /**
    * 删除文件
    */
   public boolean delete(String filePath) {
        try {
            client.removeObject(minioClient.getBucketName(),filePath);
            return true;
        } catch (Exception e) {
            log.error("====minio:删除失败，"+e.getMessage());
        }
       	return false;
    }
    
    public String getContextType(String path){
        String suffix = path.substring(path.lastIndexOf(".") + 1 );
        String type = "application/octet-stream";
        if(suffix.equals("jpg")||suffix.equals("jpeg")||suffix.equals("png")||suffix.equals("bmp")||suffix.equals("gif")){
            type = "image/jpeg";
        }
        return type;
    }
    
}

5、最后 Controller

@RestController
@RequestMapping("oss")
@AllArgsConstructor
public class OssController {
    
    private final MinioStorageService minioStorageService;
    
    /**
	 * 上传文件
	 */
	@RequestMapping("/upload")
	public R upload(@RequestParam("file") MultipartFile file) throws Exception {
		if (file.isEmpty()) {
			throw new RRException("上传文件不能为空");
		}

		//上传文件
        String path = "/psm_memory_service/picture/fore-end/"+file.getOriginalFilename();
		String url = minioStorageService.uploadFile(file.getBytes(),path);
		return R.ok().put("url", url);
    }
    
    /**
	 * 删除
	 */
	@RequestMapping("/delete/{id}")
	public R delete(@PathVariable("id") String id){
		SysOss oss = sysOssService.getById(id);
		ossFactory.build().delete(oss.getUrl());
		sysOssService.removeById(id);
		return R.ok();
	}
    
}
