为啥该代码在项目中执行文件名不是中文呢?自己postman调用就没问题呢?求解呀
```java
String fileName;
if (StringUtils.isNotBlank(month)) {
fileName = month + "考核登记表";
log.error("开始"+fileName);
} else {
fileName = year + "年" + quarter + "考核登记表";
}
fileName = fileName + ".xls";
try {
fileName = new String(fileName.getBytes(), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
log.error("最后"+fileName);
// 将工作簿写入输出流
//String encodedFileName = null;
response.setLocale(new java.util.Locale("zh","CN"));
response.setContentType("application/octet-stream; charset=utf-8");
try {
response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
```
