将网页中的table导入excel2007

公司为了测试单板的性能,使用firefox工具查看每个请求的,因此使用了firebug的YSlow工具,但是每个选项都必须复制黏贴很是麻烦,因此这里写了一个小程序,将网页中的table导入到excel中

 

以前使用的jxl.jar这个工具包不支持office2007,为了解决这方面的问题,可以使用apache的POI。

 

现在大家已经慢慢的熟悉了office2007的操作,因此我也就用07作为示范了例子

 

模拟一个table例子

<html> 
<head> 
<TITLE>class_obj_js_class</TITLE> 
<body > 
    <table>
		<tr>
			<td style="color:#00ff00">01</td>
			<td>02</td>
			<td>03</td>
		</tr>
		<tr>
			<td>11
			</td>
			<td>12</td>
			<td>13</td>
		</tr>
		<tr>
			<td style="color:#ff0000">2
			1</td>
			<td>22</td>
			<td>23</td>
		</tr>
	</table>
</body> 
</html>

读取excel中的数据,然后做相应的修改

public class ReadExcel {
	
	public static String fileName = "test.xlsx";
	
	public static void main(String[] args) {
		ReadExcel.readAndRewrite(fileName);
	}
	
	public static void readAndRewrite(String fileName){
		InputStream inp;
		try {
			inp = new FileInputStream(fileName);
			Workbook wb = WorkbookFactory.create(inp);
			//遍历所有的数据
			ReadExcel.IteratorRowCell(wb);
			//将excel的第一行第一列的数据改为huangbiao
		    Sheet sheet = wb.getSheetAt(0);
		    Row row = sheet.getRow(0);

		    //给指定的单元格设定值
		    if (cell != null){
		    	cell.setCellValue("huangbiao");
		    }
		    //设定完值之后然后通过数据流写入文件中保存起来
		    FileOutputStream fileOut = new FileOutputStream(fileName);
