Spring Boot MultipartFile upload getOriginalFileName different depending on browser

Question

I am using spring boot 1.5.7-RELEASE version and I am uploading files with following method:

@Autowired private MyService mySerice;

@RequestMapping(value = "/uploadFile", method = { RequestMethod.POST }, produces = { MediaType.MULTIPART_FORM_DATA_VALUE,
     MediaType.APPLICATION_FORM_URLENCODED_VALUE, MediaType.APPLICATION_JSON_VALUE })
public void upload(@RequestParam("file") MultipartFile uis, @RequestParam("user_id") String userId) {
    MyFile myFile = new MyFile();
    if (!uis.isEmpty()) {
        myFile.setFile(uis.getBytes());
        myFile.setName(uis.getOriginalFilename());
        myFile.setUserId(userId);
        myService.upload(myFile); 
    }
}

I am trying to upload this file to this table in MySQL:

CREATE TABLE `file_user` (
`id` int(5) UNSIGNED NOT NULL,
`user_id` bigint(20) UNSIGNED NOT NULL,
`file` mediumblob NOT NULL,
`name` varchar(50) COLLATE utf8mb4_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
ALTER TABLE `file_user` ADD PRIMARY KEY (`id`);

The front end is a simple form HTML with Ajax.

var fileInput = $("#file_form_post")[0].files[0];
var data = new FormData();
data.append("file", fileInput);
data.append("user_id", $("#txt_uid").val());
$.ajax({
    url: 'mypage.com:9002/uploadFile',
    type: 'POST',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
    headers: {Accept: "application/json"},
    success: function (r) {
                alert('Upload OK');
            },
    error: function (request, status, error) {
                alert('Upload error');
            }
    }); 

When I upload a file from Internet Explorer or Microsoft Edge the method uis.getOriginalFilename() returns the complete path.

E.G.: c:\users\daniel\myfile.txt

If I upload a file from Google Chrome the value of uis.getOriginalFileName() is only the name of file.

E.G.: myfile.txt

How could I get only the name without the path for every browsers?

Is missing some @Bean to get that?

Thanks.

Use apache commons IO. It handles a file in either Unix or Windows format.

org.apache.commons.io.FilenameUtils.getName(multipartFile.getOriginalFilename());
