SpringBoot导出压缩zip文件（doc版本）_springboot导出zip文件

通用组合数据代码

public void downloadZip(HttpServletResponse response)  {
        List<ExportData> dataList= new ArrayList<>();
        //开始压缩导出
        String fileName = "download.zip";
        response.reset();
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/octet-stream");
        response.setHeader("Content-Disposition", "attachment;filename=" + new String(fileName.getBytes(StandardCharsets.UTF_8), "ISO8859-1"));
        response.setHeader("Access-Control-Allow-Origin", "*");
        byte[] dataByteArr;
        if (CollectionUtil.isNotEmpty(dataList)) {
            try {
                dataByteArr = zipFile(dataList);
                response.getOutputStream().write(dataByteArr);
                response.flushBuffer();
            } catch (Exception e) {
                log.error("压缩zip数据出现异常", e);
                e.printStackTrace();
            }
        }
    }

压缩文件

    /**
     * zip文件
     *
     * @param dataList 数据列表
     * @return {@link byte[]}
     */
    public byte[] zipFile(List<ExportData> dataList) throws IOException {
        // 将字节写到一个字节输出流里
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try (ZipOutputStream out = new ZipOutputStream(baos)) {
            // 创建zip file in memory
            for (ExportData data: dataList) {
                ZipEntry entry = new ZipEntry("文件名.doc");
                out.putNextEntry(entry);
                out.write(data.getContent().getBytes(StandardCharsets.UTF_8));
                out.closeEntry();
            }
            baos.close();
        } catch (IOException e) {
            log.error("压缩zip数据出现异常", e);
            throw new RuntimeException("压缩zip包出现异常");
        } finally {
            baos.close();
        }
        return baos.toByteArray();
    }

 前端代码 请求接口带上"blob" 

responseType: "blob",

  res就是后端返回的流

        const blob = new Blob([res], { type: "application/zip" });
        const fileName = `批量下载`;
        if ("download" in document.createElement("a")) {
          // 非IE下载
          const elink = document.createElement("a");
          elink.download = fileName;
          elink.style.display = "none";
          elink.href = window.URL.createObjectURL(blob);
          document.body.appendChild(elink);
          elink.click();
          window.URL.revokeObjectURL(elink.href); // 释放URL 对象
          document.body.removeChild(elink);
        } else {
          // IE10+下载
          navigator.msSaveBlob(blob, fileName);
        }
