freemarker 读取template.xml ,通过response 输出文件，解决中文乱码问题

采用

try (Writer writer = new OutputStreamWriter(os, “UTF-8”))

UTF-8 内容转换

    public static void setResponseHeader(HttpServletResponse response, String fileName) {
        try {
            // fileName = "中文.xls";
             try {
                fileName = new String(fileName.getBytes(),"ISO8859-1");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
            response.setContentType("application/octet-stream;charset=UTF-8");
            //response.setCharacterEncoding("UTF-8");
            response.setHeader("Content-Disposition", "attachment;filename="+ fileName);//
            response.addHeader("Pargam", "no-cache");
            response.addHeader("Cache-Control", "no-cache");
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

 public void xml2XmlOutFromResources(HttpServletResponse response, Map<String, Object> dataMap, String templetFile, String fileName) throws IOException, TemplateException {

       //设置响应头
       ExportExcel.setResponseHeader(response, fileName);

       Configuration configuration = new Configuration(Configuration.VERSION_2_3_28);

       configuration.setDefaultEncoding("UTF-8");
       configuration.setClassLoaderForTemplateLoading(this.getClass().getClassLoader(), "");
       Template template = null;

       } catch (Exception e) {

       }

       //模板和数据模型合并生成文件
       OutputStream os = null;
