java 实现生成txt压缩后返回客户端，不知道哪错了。生成的压缩文件都是损坏的

Question

try {
OutputStream os = res.getOutputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ZipOutputStream zipOut = new ZipOutputStream(baos);
ZipEntry entry = new ZipEntry("goods.txt");
zipOut.putNextEntry(entry);
zipOut.write(bytes, 0, bytes.length);

               res.reset();
               res.setContentType("application/OCTET-STREAM;charset=GBK");
               res.setHeader("pragma", "no-cache"); 
               res.addHeader("Content-Disposition", "attachment;filename=goods.zip");
               os.write(baos.toByteArray(), 0, baos.toByteArray().length);
               zipOut.flush();
               zipOut.closeEntry();
               baos.close();
               zipOut.close();
               os.close();
          } catch (Exception e) {
