Spring启动映像上载错误

Question

当将图像上传到控制器（所有其他服务都可以正常工作）时，不存在所需的请求部分文件。我已经通过成功上传到这个Spring指南排除了邮递员。不确定缺了什么。

Spring可能版本：Edgware。构建-快照

控制器：

@RequestMapping(path = "/{account_id}/image", method = RequestMethod.POST)
public ResponseEntity uploadProfileImage(
    @RequestParam("file") MultipartFile file,
    @PathVariable String account_id) {
    ...
}

此特定配置的解决方案是将项目从带有Spring Boot 1.5.13的Edgeware移动到带有Spring Boot 2.0.1的Finchley。
