• java工具类POI导出word


    1、新建一个word,里面填写内容,如:

    2、导出wordjava类

    /**

                xwpfTUtil.replaceInPara(doc, params);  
                //替换表格里面的变量  
                xwpfTUtil.replaceInTable(doc, params);  
                OutputStream os = response.getOutputStream();  
          
                response.setContentType("application/vnd.ms-excel");

                os.flush();
