如何使用 Java 和 Spring Boot 实现批量下载简历功能？

@PostMapping("/downloadResumes")
public ResponseEntity<InputStreamResource> downloadResumes(@RequestParam("resume") List<String> resumes) throws IOException {
    // 创建临时 ZIP 文件
    Path zipFile = Files.createTempFile("resumes", ".zip");

    try (ZipOutputStream zos = new ZipOutputStream(Files.newOutputStream(zipFile))) {
        for (String resume : resumes) {
            // 假设简历文件存储在 "resumes" 文件夹中
            Path resumePath = Paths.get("resumes", resume);
            if (Files.exists(resumePath)) {
                zos.putNextEntry(new ZipEntry(resume));
                Files.copy(resumePath, zos);
                zos.closeEntry();
            }
        }
    }

    // 创建 InputStreamResource 以便于返回 ZIP 文件
    InputStreamResource resource = new InputStreamResource(new FileInputStream(zipFile.toFile()));

    // 设置响应头
    HttpHeaders headers = new HttpHeaders();
    headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=resumes.zip");

    return ResponseEntity.ok()
            .headers(headers)
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}
