看代码吧~
/** * excel表格直接下载 */public static void exportExcelByDownload(HSSFWorkbook wb,HttpServletResponse httpServletResponse,String fileName) throws Exception { //响应类型为application/octet- stream情况下使用了这个头信息的话，那就意味着不想直接显示内容 httpServletResponse.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE); //attachment为以附件方式下载 httpServletResponse.setHeader("Content-Disposition","attachment;filename=" + URLEncoder.encode( fileName + ".xls", "utf-8")); /** * 代码里面使用Content-Disposition来确保浏览器弹出下载对话框的时候。 * response.addHeader("Content-Disposition","attachment");一定要确保没有做过关于禁止浏览器缓存的操作 */ httpServletResponse.setHeader("Cache-Control", "No-cache"); httpServletResponse.flushBuffer(); wb.write(httpServletResponse.getOutputStream()); wb.close();}/** * excel以文件的形式导出 * @throws Exception */public static void exportExcelByFile(HSSFWorkbook wb,String fileName,String path) throws Exception{ ByteArrayOutputStream stream = new ByteArrayOutputStream(); wb.write(stream); FileOutputStream outputStream = new FileOutputStream(path + fileName); outputStream.write(stream.toByteArray()); stream.close(); outputStream.close();}
java查询数据导出excel并返回给浏览器下载
效果图：
1.点击导出表按钮
2.接着就会出现下图
3.点击上图中的确定按钮再接着就会出现下图
4.点击上图中的保存按钮接着就会出现下图，浏览器下载完成后的提示
5.打开下载好的文件如下图
好了，废话不多少，上代码
