一、上傳

    public @ResponseBody
    ApiResult<UploadResult> upload(@RequestParam("file") MultipartFile file, @RequestParam(value="appId") String appId, @RequestParam("group") String group, @RequestParam("fileName") String originFileName){
        try {
            String suffix = file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf(".") + 1).toLowerCase();
            if(!allowUploadSuffixes.contains(suffix)){
                throw new IotBaseException(9999, "不允許上傳該檔案型別");
            }
            String fileKey = UUID.randomUUID().toString() + "."+suffix;

            FileSystemClient client = FileSystemClient.getClient(group);
            String url = client.upload(fileKey, file.getBytes(), appId);

            UploadFileEntity entity = new UploadFileEntity();
            entity.setAppId(appId);
            entity.setGroupName(group);
            entity.setFileName(originFileName);
            entity.setFileUrl(url);
            entity.setMimeType(file.getContentType());
            entity.setProvider(client.getProvider().name());
            entity.setCreatedAt(new Date());
            uploadFileEntityMapper.insert(entity);

            return new  ApiResult<>(new UploadResult(url, originFileName));
        } catch (Exception e) {
            e.printStackTrace();
            throw new IotBaseException(ExceptionCode.SYSTEM_ERROR.code, "上傳失敗");
        }
    }
 

二、訪問

• 在application.yml檔案中加入

spring:
  resources:
    static-location: classpath:/static/upload/

上面這一步好像不填也沒關係

• 建立配置

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/"
