springmvc下载中文文件名称为下划线
springboot项目中,在下载文件的时候,通过封装ResponseEntity,将文件流写入body,这种下载文件的方式,造成了下载的文件名为正文显示为下划线的形式;
这个问题很好解决
直接将输入的文件名的编码格式定义成GBK格式;
如下代码
public static ResponseEntity<FileSystemResource> export(File file) throws UnsupportedEncodingException {
if (file == null) {
return null;
}
//这个位置对文件名进行编码
String fileName = new String (file.getName().getBytes("GBK"),"ISO-8859-1");
HttpHeaders headers = new HttpHeaders();
headers.add("Cache-Control", "no-cache, no-store, must-revalidate");
headers.add("Content-Disposition", "attachment; filename=" +fileName);
headers.add("Pragma", "no-cache");
headers.add("Expires", "0");
headers.add("Last-Modified", new Date().toString());
headers.add("ETag", String.valueOf(System.currentTimeMillis()));
return ResponseEntity
.ok()
.headers(headers)
.contentLength(file.length())
.contentType(MediaType.parseMediaType("application/octet-stream"))
.body(new FileSystemResource(file));
}
java生成文件名时汉字变为下划线?
public static void exportToExcel(String uid, String name, String htmlText,
HttpServletRequest request, HttpServletResponse response) {
htmlText = htmlText.replaceFirst("<table>", "<tableFirst>");
htmlText = htmlText.replaceAll("<table>",
"<table cellpadding=\"3\" cellspacing=\"0\" border=\"1\" rull=\"all\"
style=\"border-collapse: collapse\">");
htmlText = htmlText.replaceFirst("<tableFirst>", "<table>");
try (OutputStream out = response.getOutputStream()) {
String fileName = name+ "_" + DateUtils.getNow("yyyyMMddHHmmss");
// fileName = new String(fileName.getBytes(),"utf-8")+ ".xls";
if ("large".equals(htmlText)) {
ReportingPo report = reportingService.getByUid(uid);
Map<String, Object> formParameters = generationService.getFormParameters(request.getParameterMap(),
report.getDataRange());
ReportTable reportTable = generationService.getReportTable(report, formParameters);
htmlText = reportTable.getHtmlText();
}
// response.reset();
response.addHeader("Content-Disposition", "attachment;filename=" +
new String(fileName.getBytes("utf-8"),"iso-8859-1")+ ".xls");
// response.setHeader("Content-Disposition", String.format("attachment; filename=%s", fileName));
response.setContentType("application/vnd.ms-excel; charset=utf-8");
response.setCharacterEncoding("utf-8");
response.addCookie(new Cookie("fileDownload", "true"));
// out.write(new byte[] { (byte) 0xEF, (byte) 0xBB, (byte) 0xBF }); // 生成带bom的utf8文件
out.write(htmlText.getBytes("utf-8"));
out.flush();
} catch (Exception ex) {
throw new RuntimeException(ex);
}
}
注意这里两个编码
new String(fileName.getBytes("utf-8"),"iso-8859-1")+ ".xls"
