Java批量导出word压缩后的zip文件

一、js代码，由于参数比较大所以利用form表单使用post导出

二、controller代码（读完压缩文件后删除文件）

/**
    	 *
    	 * @Description 考核成绩汇总考核表批量导出压缩
    	 * @Fcunction exportWordsZip
    	 * @param response
    	 * @return ReturnDatas
    	 *
    	 */
    	@ResponseBody
    	@SystemControllerLog(description = "考核成绩汇总考核表批量导出压缩")
    	@RequestMapping(value = "exportWordsZip")
    	public ReturnDatas exportWordsZip(HttpServletResponse response, String id, String type) {
    		ReturnDatas returnDatas = ReturnDatas.getSuccessReturnDatas();
    		try {
    			response.setCharacterEncoding("UTF-8");
    			response.setContentType("application/msexcle");
    			response.setHeader("content-disposition", "attachment;filename=" + new String("考核成绩汇总表".getBytes("gb2312"), "ISO8859-1") + ".zip");
    			String fileUrl = assessGradeSumService.exportWordsZip(id,type);
    			OutputStream outputStream = response.getOutputStream();
    			BufferedInputStream bis = new BufferedInputStream(new FileInputStream(fileUrl));;
    			BufferedOutputStream bos = new BufferedOutputStream(outputStream);
    			byte[] buff = new byte[2048];
    			int bytesRead;
    			while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
    				bos.write(buff, 0, bytesRead);
    			}
    			bis.close();
    			bos.close();
    			outputStream.close();
    			File zip = new File(fileUrl);
    			if (zip.exists() && zip.isFile()) {
    				zip.delete();
    			}
    			return returnDatas;
    		} catch (Exception e) {
    			e.printStackTrace();
    			LogUtil.error("考核成绩汇总考核表批量导出压缩异常：" + e.getMessage(), e);
    			returnDatas.setStatus(ReturnDatas.ERROR);
    			returnDatas.setMessage("考核成绩汇总考核表批量导出压缩异常。");
    		}
    		return returnDatas;
    	}

三、实现类代码，其中exportWord()和exportWordForSpecific()都是具体的word导出方法，生成zip压缩文件后删除word文件，ZipUtils是压缩文件工具类

/**
    	 *
    	 * @Fcunction exportWordsZip
    	 * @param id
    	 * @param type
    	 * @return String
    	 *
    	 */
    	@Override
    	public String exportWordsZip(String id, String type)throws Exception{
    		String[] ids = id.split("@@");
    		List<File> fileList = new ArrayList<>();
    		String url = "C:\\";
    		for (int i = 0; i < ids.length; i++) {
    			String id_name = ids[i];
    			String id_value = id_name.split("name")[0];
    			String name = id_name.split("name")[1];
    			String docUrl = url + name + ".doc";
    			fileList.add(new File(docUrl));
    			XWPFDocument workbook = null;
    			if ("0".equals(type)) {//按次
    				workbook = exportWord(id_value);
    			} else {//表单条目
    				workbook = exportWordForSpecific(id_value);
    			}
    			FileOutputStream out = new FileOutputStream(docUrl);
    			workbook.write(out);
    		}
    		String zipUrl = url+"考核成绩汇总表.zip";
    		FileOutputStream fos = new FileOutputStream(new File(zipUrl));
    		ZipUtils.toZip(fileList, fos);
    		for (File out:fileList) {
    			if (out.exists() && out.isFile()) {
    				out.delete();
    			}
    		}
    		return zipUrl;
    	}
