java MultipartFile多文件上传/通过文件夹解析所有文件

MultipartFile多文件:

public Boolean upload(MultipartFile[] files) throws Exception {
if (null != files && files.length > 0) {
//用于判断文件个数
final int length = files.length;
for (MultipartFile file : files) {
final String originalFilename = file.getOriginalFilename();
assert originalFilename != null;
//后缀,用于判断文件类型
String suffix = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
       //获取输文件入流
       final InputStream inputStream = file.getInputStream();
     //添加逻辑操作...
}
}
return true;
}

通过文件夹上传:

    public Boolean uploadByDirectory(String path) throws Exception {
        File file = new File(path);
        File[] tempList = file.listFiles();
        //遍历文件夹内文件
        for (int i = 0; i < Objects.requireNonNull(tempList).length; i++) {
            File excel = tempList[i];

            FileInputStream fileInputStream = null;
            final String fileName = excel.getName();
            //判断后缀是什么类型
            String suffix = fileName.substring(fileName.lastIndexOf(".") + 1);
            //创建文件输入流
            fileInputStream = new FileInputStream(excel);
            //执行操作....
            
        }
        return true;
    }
