java 接受带有中文的get请求文件下载时的问题
参数是接受到了 , debug的时候也能看的到 , 但是奇怪的是就是找不到文件
@ApiOperation(value = "文件下载/图片预览")@GetMapping(value = "/file/{type:download|view}")
public Object fileDownloadOrView(ModelMap modelMap,String filePath,String fileName,@PathVariable ("type") String type,
HttpServletResponse responsen ) throws Exception {
if(StringUtils.isBlank(filePath)){
modelMap.put("msg", "参数错误!!!");
return setModelMap(modelMap, HttpCode.BAD_REQUEST);
}
String note=new String(filePath.trim().getBytes("ISO-8859-1"), "UTF-8");
File file = new File(note);
if(file.exists() && file.isFile()){
if("download".equals(type)){
String fileSuffix = file.getName().substring(file.getName().lastIndexOf("."),file.getName().length());
if(StringUtils.isEmpty(fileName)){
fileName = UUID.randomUUID().toString();
}
fileName = fileName+fileSuffix;
try {
responsen.setContentType("multipart/form-data");
responsen.addHeader("Content-Length", "" + file.length());
responsen.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(fileName, "UTF-8"));
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
}
FileInputStream inputStream = null;
OutputStream outputStream = null;
try {
inputStream = new FileInputStream(file);
outputStream = responsen.getOutputStream();
IOUtils.copy(inputStream, outputStream);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
inputStream.close();
outputStream.flush();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
} else {
modelMap.put("msg", "文件不存在!!!");
return setModelMap(modelMap, HttpCode.CONFLICT);
}
}
虽然不知道为什么原因 , 但是
String note=new String(filePath.trim().getBytes("ISO-8859-1"), "UTF-8");
File file = new File(note);
确实吧路劲这么着的转化一下就行了
