Java操作Jxl实现数据交互。三部曲——《第二篇》

Java操作Jxl实现.xsl及.xsls两种数据表格进行批量导入数据到SQL server数据库。

本文实现背景Web项目:前台用的框架是Easyui+Bootstrap结合使用需要引入相应的Js、Css文件页面:Jsp、拦截请求:Servlet、逻辑处理:ClassBean、数据库:SQLserver

:Bean中操作SQL语句进行处理是公司内部方法,可替换为其它方法自行扩展!主要看代码逻辑业务处理!

首先我们看见Easyui中的datagrid数据网格列表中没有任何数据:

其次创建一个xsl文件以下是需要导入的数据格式:

让我们把注意力放到SQLserver数据库:

点击导入按钮后弹出一个窗口选择我们刚刚创建的Excel文件,最后点击导入

 

 

 导入成功此时此刻Easyui中的datagrid数据网格中已有了7条我们之前创建的记录!

 

 

 

 

 

我们回到数据库进行查看数据,果然和预期效果一样与Excel表格数据一致证明导入成功!

Jsp代码: 

注:from中的enctype="multipart/form-data"属性是必加的,要想进行上传必须使用HTML中的文件控件,且必须使用enctype进行分装,表示将表单按照二进制的方式提交。即所有的操作表单此时不再是分别提交,否则将所有内容都按照二进制的方式提交。如果要上传文件,表单则必须封装。但是当一个表单使用了enctype="multipart/form-data"封装后,其它的非表单控件的内容就无法通过request内置对象获取,此时在Servlet中必须调用SmartUpload类中提供的getRequest()方法获取全部的请求参数
