文件下载到本地

打开本地文件的属性查看路径 

Java代码

    @ApiOperation(value = "文件下载", notes = "导出excel表格")
    @RequestMapping(value = "/clientDownload", method = RequestMethod.GET)
    public void orderFile(ModelMap model, HttpServletRequest request, HttpServletResponse response, @RequestParam String exeName) {
        InputStream inputStream = null;
        //设置下载文件的名字
        exeName=exeName+".xls";
        try{
            //String contextRealPath = FilePropertyUtil.getFilePathProperty().getProperty("temPath");//request.getSession().getServletContext().getRealPath("/");
            //这里是本地文件的路径
            inputStream = new FileInputStream(new File("文件的路径记得加后缀C:Users\antong.xls"));

            // 清空response
            response.reset();
            // 设置response的Header
            response.addHeader("Content-Disposition", "attachment;filename=" + new String(exeName.getBytes("gb2312")));
            byte[] b = new byte[1024];
            int len = -1;
            OutputStream outputStream = response.getOutputStream();
            while ((len = inputStream.read(b)) !=-1) {
                
                outputStream.write(b, 0, len);  //读取字节，从0到len长度
            }
            inputStream.close();
            //setSuccess(model);
        }catch(Exception e){
            e.printStackTrace();
            if(inputStream!=null){
                try {
                    inputStream.close();
                } catch (IOException e1) {
                }
            }
            //setFailure(model);
        }
    }
