			<artifactId>qiniu-java-sdk</artifactId>
			<qiniu-java-sdk.version>7.7.0</qiniu-java-sdk.version>
		</dependency>

二:具体实现



@RestController
@RequestMapping("/sys/oss/qiniu")
public class OssController {
   
   
    @Autowired
    private OssQiNiuHelper ossQiNiuHelper;

    @Value("${jeecg.oss.qiniu.domain}")
    private String fileDomain;

    /**
     * 七牛云文件上传
     *
     * @param file 文件
     * @return
     */
    @PostMapping(value = "/upload")
    public Result<?> upload(MultipartFile file) {
   
   
        if (file == null) {
   
   
            return Result.error("上传文件不能为空");
        }
        try {
   
   
            FileInputStream fileInputStream = (FileInputStream) file.getInputStream();
            String originalFilename = file.getOriginalFilename();
            String fileExtend = originalFilename.substring(originalFilename.lastIndexOf("."));
            String yyyyMMddHHmmss = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date());
            //默认不指定key的情况下，以文件内容的hash值作为文件名
            String fileKey = UUID.randomUUID().toString().substring(0,16).replace("-", "") + "-" + yyyyMMddHHmmss + fileExtend;
            Map<String, Object> map = new HashMap<>();
            DefaultPutRet uploadInfo = ossQiNiuHelper.upload(fileInputStream, fileKey);
            map.put("fileName", uploadInfo.key);
            map.put("name", originalFilename)
