解决导出excel文件名中文乱码的问题

设置响应头文件名称编码
URLEncoder.encode(fileName, "UTF-8") 

String fileName = "工作任务办理单";
//输出Excel文件
OutputStream output = response.getOutputStream();
response.reset();
//设置响应头
response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8") + ".xls");
response.setContentType("application/x-xls");
wb.write(output);
output.close();
