Hello, When I update springboot 1.x to 3.2， old controller method whit function is download zip file not work.
Can you help me? I tried a lot of times but failed.
@RequestMapping(value = "/download/v1", method = RequestMethod.GET)
ResponseEntity<FileSystemResource> userDownloadWordsSync(@RequestParam(name = "bookId") Long bookId) throws IOException {
String path = bookService.download(bookId);
String contentDisposition = ContentDisposition
.builder("attachment")
.filename(path)
.build().toString();
File file = new File(path);
if (file.exists()) {
return ResponseEntity.ok()
.header(HttpHeaders.CONTENT_DISPOSITION, contentDisposition)
.contentType(MediaType.APPLICATION_OCTET_STREAM)
.body(new FileSystemResource(path));
} else {
return ResponseEntity.notFound().build();
}
}
Thank you very much!

I replicated this setup in a sample application and this works for me. I'll assume that there's a setup error somewhere.
1.x to 3.2 is a very large gap so I would suggest upgrading your application from minor version to minor version following the upgrade guides.
If you can provide a minimal sample application that replicates the problem in Spring Boot 3.2 please share it here and we'll reconsider this issue. Thanks!
