后端代码
- 其中 UserDto 为接收 json 数据的对象
- 注解为 @RequestPart，用 @RequestParam 接收不到 json 数据
@PostMapping(value = "/uploadFileAndJson")
public void uploadFileAndJson(
@RequestPart("file") MultipartFile file,
@RequestPart("userDto") UserDto userDto) {
// 业务代码
}
前端请求
- 这里使用 idea 的 http client
POST http://localhost:8080/uploadFileAndJson

--WebAppBoundary--
Content-Disposition: form-data; name="userDto";
Content-Type: application/json
{"username":"admin", "password":"123456"}
--WebAppBoundary
Content-Disposition: form-data; name="file"; filename="fileUpload.json"
