SpringMvc中导出excel时文件名中文乱码问题

问题描述

在使用springmvc导出Excel时，设置response响应头如下

response.setHeader("Content-Disposition", "attachment;filename=测试.xls");
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setCharacterEncoding("UTF-8");

下载excel后文件名称乱码

解决方法

response.setHeader("Content-Disposition", "attachment;filename*=UTF-8''" + URLEncoder.encode(fileName,"UTF-8"));
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setCharacterEncoding("UTF-8");

原因

有待了解
