2018-10-18 SpringMvc下载中文件时，中文文件名显示空白

1. 问题:获得Excel文件流并下载的过程中，如果文件名称包含中文，下载的文件中文显示空白 ( ).xls

public static void download(HttpServletRequest request, HttpServletResponse response) throws Exception {String fileName = "下载文件测试.xls";String filePath = "D:\\";//设置响应头和客户端保存文件名response.setCharacterEncoding("UTF-8");response.setContentType("multipart/form-data");response.setHeader("Content-Disposition", "attachment;fileName=" + fileName);//用于记录以完成的下载的数据量，单位是bytetry {//打开本地文件流InputStream inputStream = new FileInputStream(filePath);//激活下载操作OutputStream os = response.getOutputStream();//循环写入输出流byte[] b = new byte[2048];int length;while ((length = inputStream.read(b)) > 0) {os.write(b, 0, length);}// 这里主要关闭。os.close();inputStream.close();} catch (Exception e){throw e;}
}

2. 解决方案：在设置fileName的时候进行转码

fileName = URLEncoder.encode(fileName,"utf-8");
