response 文件下载
今天看项目中别人用 response 写的个下载功能，复制一下当中的代码public String execute() throws Exception {ApArticleAttachEntity file = baseDataService.getArticleAttach(attachId);if (file == null)return NONE;String fileName = (file.getAttachName() == null|| "".equals(file.getAttachName())) ? "unknownFileName.tmp" : file.getAttachName();String suffixName = fileName.substring(fileName.lastIndexOf(".")+1, fileName.length());if("doc".equalsIgnoreCase(suffixName)){response.setContentType("application/msword");}else if("xls".equalsIgnoreCase(suffixName)){response.setContentType("application/vnd.ms-excel");}else if("pdf".equalsIgnoreCase(suffixName)){response.setContentType("application/pdf");}else{response.setContentType("application/download");}response.setHeader("Content-Disposition", "attachment; filename=\""+ new String(fileName.getBytes("GBK"), "iso8859-1") + "\"");OutputStream os = response.getOutputStream();os.write(file.getAttachContent());os.flush();os.close();return NONE;}
