先上代码：
File file = new File("C:\\Users\\71028\\Desktop\\excel.xlsx");
if (file.exists()) {
byte[] data = null;
try {
FileInputStream inputStream = new FileInputStream(file);
data = new byte[inputStream.available()];
inputStream.read(data);
// 这里URLEncoder.encode可以防止中文乱码 当然和easyexcel没有关系
String fileName = URLEncoder.encode("测试", "UTF-8").replaceAll("\\+", "%20");
response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + fileName + ".xlsx");
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
response.setCharacterEncoding("utf-8");
response.getOutputStream().write(data);
} catch (Exception e) {
}
}
注意response要设置contentType
