准备一个导出的模板

controller层代码

    /**
     * 按模板导出数据
     * @param response
     */
    @PostMapping(value = "/exportByTem",produces = "application/octet-stream")
    public void exportJg(HttpServletResponse response,HttpServletRequest request){
    
    
        /**
         *如果是在SSM项目中用以下方式，模板直接放在webapp下
         * String path = request.getSession().getServletContext().getRealPath("/")+"template/技工报名表.xls";
         * TemplateExportParams params = new TemplateExportParams(path);
         */
        //取到要导出的模板
        TemplateExportParams params = new TemplateExportParams("\\static\\template\\报名表.xls");
        if (null!=params){
