后台代码

/**

* 模板下载

* @param request

* @return

*/

@RequestMapping("/downloadTemplate")

public ResponseEntity downloadTemplate(HttpServletRequest request){

ResponseEntity entity = null;

try {

File file = new File(ResourceUtils.getURL("classpath:static").getPath().replace("%20"," ").replace('/', '\\') + "\\securityParameter\\template\\网络安全台账（模板）.xlsx");

byte[] body = null;

InputStream is = new FileInputStream(file);

body = new byte[is.available()];

is.read(body);

HttpHeaders headers = new HttpHeaders();

String downlaodFilename = URLEncoder.encode(file.getName(),"utf-8");

headers.add("Content-Disposition", "attchement;filename=" + downlaodFilename);

headers.add("Content-Type", "application/vnd.openxmlformats-officedocument.wordprocessingml.document");

HttpStatus statusCode = HttpStatus.OK;

entity = new ResponseEntity(body, headers, statusCode);

is.close();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return entity;

}

修改之后的代码

/**

* 模板下载

* @param request

* @return

*/

@RequestMapping("/downloadTemplate")

public ResponseEntity downloadTemplate(HttpServletRequest request){

ResponseEntity entity = null;

try {

//File file = new File(ResourceUtils.getURL("classpath:static").getPath().replace("%20"," ").replace('/', '\\') + "\\securityParameter\\template\\网络安全台账（模板）.xlsx");

ClassPathResource resource = new ClassPathResource("\\static\\securityParameter\\template\\网络安全台账（模板）.xlsx");

InputStream is = resource.getInputStream();

byte[] body = null;

body = new byte[is.available()];

is.read(body);

HttpHeaders headers = new HttpHeaders();

String downlaodFilename = URLEncoder.encode("网络安全台账（模板）.xlsx","utf-8");

headers.add("Content-Disposition", "attchement;filename=" + downlaodFilename);

headers.add("Content-Type", "application/vnd.openxmlformats-officedocument.wordprocessingml.document");

HttpStatus statusCode = HttpStatus.OK;

entity = new ResponseEntity(body, headers, statusCode);

is.close();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return entity;

}

结果如下：
