在Angular 2和Spring MVC中上载具有其他表单字段的文件

您需要使用

@RequestPart

@RequestParam

consumes

@RequestMapping(value = "/file",method = RequestMethod.POST, consumes = "multipart/form-data")@ResponseBodypublic ResponseEntity<String> addUser(@RequestPart("uploadFile") MultipartFile file, @RequestPart("info") ExampleModel model){}

您还需要调整

FormData

formData.append('uploadFile', file, file.name);formData.append('info', new Blob([JSON.stringify(this.model)],        { type: "application/json"        }));
