Spring启动映像上传错误

Question

在将图像上传到控制器时继续获取 Required request part 'file' is not present（所有其他服务工作正常）。我已经成功上传到这个 spring-guide，排除了 Postman。不确定缺少什么。

Spring 可能版本: 埃奇韦尔.BUILD-SNAPSHOT

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 Spring Boot 1.5.13 的 Edgeware 移动到 Spring Boot 2.0.1 的 Finchley。
