本文整理了Java中org.springframework.web.multipart.MultipartFile类的一些代码示例，展示了MultipartFile类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MultipartFile类的具体详情如下：
包路径：org.springframework.web.multipart.MultipartFile
类名称：MultipartFile

MultipartFile介绍

[英]A representation of an uploaded file received in a multipart request.

The file contents are either stored in memory or temporarily on disk. In either case, the user is responsible for copying file contents to a session-level or persistent store as and if desired. The temporary storage will be cleared at the end of request processing.
[中]在多部分请求中接收的上传文件的表示形式。
文件内容要么存储在内存中，要么临时存储在磁盘上。在这两种情况下，如果需要，用户负责将文件内容复制到会话级别或持久存储。临时存储将在请求处理结束时清除。

代码示例

public File convert(MultipartFile file)

  File convFile = new File(file.getOriginalFilename());
  convFile.createNewFile(); 
  FileOutputStream fos = new FileOutputStream(convFile); 
  fos.write(file.getBytes());
  fos.close(); 
  return convFile;
}
