将内容类型更改为 application/pdf

    @Override
    public void handle(HttpRequest request, HttpResponse response, HttpContext context)
            throws HttpException, IOException 
        {
        try{
            File file = new File("/my/path/file.pdf");
            FileEntity body = new FileEntity(file, "application/pdf");
            response.setHeader("Content-Type", "application/force-download");
            response.setHeader("Content-Disposition","attachment; filename=file.pdf");
            response.setEntity(body);

        }catch(Exception e)
        {
            e.printStackTrace();
        }

        }

};
