我想从服务器返回一个Zip文件。对于存在的文件，它的工作正常，文件得到返回，一切正常。我的问题是不存在的文件。这里我想返回一个404-Error，但目前返回的是500，因为“java.io.FileNotFoundException：无法在文件系统中解析URL [...]，以检查其内容长度“在控制器中无法执行。
下面是我的控制器代码：

@GetMapping("analysis/daily/{year}/{month}/{day}/{mode}")
public ResponseEntity<Resource> getDailyAnalysis(
@PathVariable("year") int year, 
@PathVariable("month") int month,
@PathVariable("day") int day, 
@PathVariable("mode") AnalysisSelection type) {
    try {
        Resource resource;
        Path fileBasePath = Path.of("Analysis", "ZIP", "Daily",
                String.valueOf(year),
                String.valueOf(month),
                String.valueOf(day));
        switch (type) {
            case ByItem -> {
                fileBasePath = fileBasePath.resolve("SingleItemAnalysis.zip");
            }
            case ByAuthor -> {
                fileBasePath = fileBasePath.resolve("Author.zip");
            }
            case ByType -> {
                fileBasePath = fileBasePath.resolve("Type.zip");
            }
            case ByIndustry -> {
                fileBasePath = fileBasePath.resolve("Industry.zip");
            }
            default -> {
                throw new ResponseStatusException(HttpStatus.BAD_REQUEST);
            }
        }
        resource = new UrlResource(fileBasePath.toUri());
        return ResponseEntity.ok().contentType(MediaType.parseMediaType("application/zip"))
                .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + resource.getFilename() + "\"")
                .body(resource);
    } catch (Exception e) {
        //e.printStackTrace();
        throw new ResponseStatusException(HttpStatus.NOT_FOUND);
    }

}

奇怪的是，堆栈跟踪指向Spring Security JWT-Token实现：特别是这一行：“filterChain.doFilter（请求，响应）;“

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
    String jwt = getJwtFromRequest(request);

    if (StringUtils.hasText(jwt) && jwtTokenProvider.validateToken(jwt)) {
        String mail = jwtTokenProvider.getUserMailFromToken(jwt);
        UserDetails userDetails = appUserDetailedService.loadUserByUsername(mail);
        UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());

        authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
        SecurityContextHolder.getContext().setAuthentication(authentication);
    }

    filterChain.doFilter(request, response);
}

以下是整个Stack Trace：
