OpenFeignFormData

服务端接口代码如下：

/**
* 上传数据+实体信息
*/
@RequestMapping("/upload")
public String doctorAnalysis(HttpServletRequest request, @RequestParam(value = "userinfo") String param, @RequestParam(value = "file") MultipartFile file) {
logger.info("userinfo json => {}", param);
logger.info("上传成功{}", file.getOriginalFilename());
File saveFile = new File("D:\\"+file.getOriginalFilename());
if (!saveFile.exists()) {
saveFile.mkdirs();
}
try {
file.transferTo(saveFile);
} catch (IOException e) {
logger.error(e.getMessage(), e);
e.printStackTrace();
}
return "上传成功";
}

PostMan 如下

 OpenFeign

@FeignClient(name = "vipsoft", url = "${api.url}")
public interface ICallbackFeignService {
/**
* 上传文件
*
* 注意: 使用openfeign传递参数含有文件类型时必须指定 cOnsumes= MediaType.MULTIPART_FORM_DATA_VALUE
*
* @param param 需要将对象转成JSON，如果直接传对象出去，将会变成 Key Value的形式
* @return
*/
@PostMapping(value = "/upload", cOnsumes= MediaType.MULTIPART_FORM_DATA_VALUE)
String upload(@RequestPart("result") String param, @RequestPart("file") MultipartFile file);
}
