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responentity，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 responentity<filesystemresource> export(file file) throws unsupportedencodingexception {        if (file == null) {     关于感动的作文       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(say的现在分词"content-disposition", "attachment; filename=" +filename);        headers.add("pragma", "no-cache");        headers.add("expires", "0");        headers.add("last-modified", new date().tostring());        headers.add("etag", stri国庆作文400字四年级ng.valueof(system.currenttimemillis()));        return responentity                .ok()                .headers(headers)                .contentlength(file.length())                .contenttype(mediatype.parmediatype("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,httprvletrequest request, httprvletrespon respon) {   htmltext = htmltext.replacefirst("<table>", "<tablefirst>");   htmltext = htmltext.replaceall("<table>",      "<table cellpadding=\"3\" cellspacing=\"0\" border=\"1\" rull=\"all\"style=\"border-collap: collap\">");   htmltext = 环境效益htmltext.replacefirst("<tablefirst>", "<table>");   try (outputstream out = respon.getoutputstream()) {    string filename = name+ "_" + dateutils.getnow("yyyymmddhhmmss");//    filename = new string(filename.getbytes(),"utf-8")+ ".xls";    if ("large".equals(htmltext)) {      reportingpo report = reportingrvice.getbyuid(uid);      map<string, object> formparameters = generationrvice.getformparameters(request.getparametermap(),report.getdatarange());      reporttable reporttable = generationrvice.getreporttable(report, formparameters);      htmltext = reporttable.gethtmltext();    }//    respon.ret();    respon.addheader("content-disposition", "attachment;filename=" +new string(filename.getbytes("utf-8"),"iso-8859-1")+ ".xls");//    respon.theader("content-disposition", string.format("attachment; filename=%s", filename));    respon.tcontenttype("application/vnd.ms-excel; chart=utf-8");    respon.tcharacterencoding("utf-8");    respon.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 str小学四年级英语课件ing(filename.getbytes("utf-8"),"iso-8859-1")+ ".xls"
