## File转换为MultipartFile ``` File targetFile = new File(""); MultipartFile multipartFile = new MockMultipartFile("targetFile", new FileInputStream(targetFile)); ```

``` @Override public void uploadFile(MultipartFile multipartFile) { <!--判断是否为null--> if (multipartFile.equals("") || multipartFile.getSize() <= 0) { multipartFile = null; return null; } //MultipartFile转换为File File file = null;
