如何将文件或者图片压缩成zip文件压缩包

代码：

@RestController
@RequestMapping("/download")
public class DownloadController {
 
    @GetMapping("/studentWork")
    public ResponseEntity downloadStudentWork() {
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
 
        String encodedFileName = "作品名称-学生姓名.zip";
//        StringBuffer stringBuffer = new StringBuffer();
//        stringBuffer.append("作品名称"+"-学生姓名.zip");
//
        try {
            encodedFileName = URLEncoder.encode(encodedFileName, StandardCharsets.UTF_8.toString());
            System.out.println(encodedFileName);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        headers.setContentDispositionFormData("attachment", encodedFileName);
        StreamingResponseBody responseBody = outputStream -> {
            try (ZipOutputStream zipOut = new ZipOutputStream(outputStream)) {
                // 假设这是学生的作品海报图片文件流
                InputStream imgStream = getStudentPosterData();
                addToZip(zipOut, imgStream, "作品封面.jpg");
 
 
                // 添加更多附件，如果有的话
                zipOut.finish();
            } catch (IOException e) {
                // 处理异常
            }
        };
 
        return new ResponseEntity<>(responseBody, headers, HttpStatus.OK);
    }
 
    private void addToZip(ZipOutputStream zipOut, InputStream inputStream, String fileName) throws IOException {
        ZipEntry zipEntry = new ZipEntry(fileName);
        zipOut.putNextEntry(zipEntry);
 
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            zipOut.write(buffer, 0, bytesRead);
        }
 
        zipOut.closeEntry();
        inputStream.close();
    }
 
    // 获取学生作品海报图片数据的示例方法
    private InputStream getStudentPosterData() throws FileNotFoundException {
        FileInputStream inputStream = new FileInputStream("C:\\Users\\admin\\Pictures\\Saved Pictures\\微信图片_20230914093742.png");
        String filePath =  "C:\\Users\\admin\\Pictures\\Saved Pictures\\微信图片_20230914093742.png";
        File file = new File(filePath);
        if (file.exists()){
            System.out.println("文件存在");
        }else {
            throw new RuntimeException();
        }
        return inputStream;
    }
