多个excel组成zip文件下载

代码示例

workbookMap   key是excle文件名 value是XSSFWorkbook

public static void downloadExcelForZip(HttpServletResponse response, Map<String, XSSFWorkbook> workbookMap, String zipName) throws IOException {
    ZipOutputStream out = null;

    try {
        response.setContentType("application/*");
        response.setHeader("content-disposition", "attachment;filename=" + new String(zipName.getBytes("gb2312"), "ISO8859-1"));
        response.setCharacterEncoding("UTF-8");
        out = new ZipOutputStream(response.getOutputStream());
        Iterator var4 = workbookMap.keySet().iterator();

        while(var4.hasNext()) {
            String fileName = (String)var4.next();
            XSSFWorkbook workbook = (XSSFWorkbook)workbookMap.get(fileName);
            ZipEntry entry = new ZipEntry(fileName);
            out.putNextEntry(entry);
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            workbook.write(bos);
            bos.writeTo(out);
            out.closeEntry();
        }

        out.flush();
    } catch (IOException var12) {
    } finally {
        if (out != null) {
            out.close();
        }

    }
}
