Answer 1

@GetMapping
public ResponseEntity<List<String>> fileTree(@RequestParam String path) {
    File file = new File(BASE_PATH + path);
    // check if file exists etc
    return ResponseEntity.ok(Arrays.stream(file.listFiles())
                                   .map(File::getName)
                                   .collect(Collectors.toList()));
}

Something like that should work, basically you can get the files inside another file with File#listFiles and then do with them wathever you want.
