如何使用 Java 和 Spring Boot 实现批量简历下载？

<form>
  <input type="checkbox" name="resume" value="resume1.pdf"> resume 1
  <input type="checkbox" name="resume" value="resume2.pdf"> resume 2
  <input type="submit" value="download">
</form>

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

  // 添加选中的简历到 ZIP 文件
  try (ZipOutputStream zos = new ZipOutputStream(Files.newOutputStream(zipFile))) {
    for (String resume : resumes) {
      Path resumePath = Paths.get("resumes", resume);
      if (Files.exists(resumePath)) {
        zos.putNextEntry(new ZipEntry(resume));
        Files.copy(resumePath, zos);
        zos.closeEntry();
      }
    }
  }

  // 将 ZIP 文件作为响应返回
  InputStreamResource resource = new InputStreamResource(new FileInputStream(zipFile.toFile()));
  return ResponseEntity.ok()
      .headers(getDefaultHttpHeaders("resumes.zip"))
      .contentType(MediaType.APPLICATION_OCTET_STREAM)
      .body(resource);
}
