先说结论，代码顺序问题

response.setContentType("application/octet-stream; charset=UTF-8");byte[] a = new byte[1000];while (-1!=ips.read(a)){ops.write(a);}response.setHeader("Content-Disposition","attachment;fileName=template.xlsx");

setHeader的顺序一定要在write前

修正代码

ClassPathResource classPathResource = new ClassPathResource("template/salary.xlsx");InputStream ips = classPathResource.getInputStream();OutputStream ops = response.getOutputStream();response.setContentType("application/octet-stream; charset=UTF-8");response.setHeader("Content-Disposition","attachment;fileName=template.xlsx");byte[] a = new byte[1000];while (-1!=ips.read(a)){ops.write(a);}
