本地上传图片接口

    @PostMapping("/upload")
    @ApiOperation("图片上传")
    public GlobalResponse<?> upload(@RequestParam("file") MultipartFile file){
        log.info(file.toString());
        GlobalResponse<?> result = ossClient.uploadFile(file);
        return GlobalResponse.success(result);
    };

feign接口定义

@RequestMapping({"/api"})
public interface OssClient {
    @PostMapping({"/uploadFile"})
    GlobalResponse<?> uploadFile(@RequestParam("file") MultipartFile file);

    @GetMapping({"/previewFile"})
    @ResponseBody
    void previewFile(@RequestParam(required = false) String fileName, HttpServletResponse response);

    @GetMapping({"/downloadFile"})
    @ResponseBody
    void downloadFile(@RequestParam(required = false) String fileName, HttpServletResponse response);
}

@FeignClient(name = "file", url = "http://localhost:8081", configuration = FeignSupportConfig.class)
public interface UploadClient {
    @PostMapping(value = "/upload-file", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    String fileUpload(@RequestPart(value = "file") MultipartFile file);
