SSH 导入导出excel 谁有这块的资料吗?
最近要开发一个导入导出功能,框架式SSH,数据库是oracle。在网上看了一下,很多都只有代码,有没有可以运行的项目之类的?链接也行,如果有知道的麻烦回复下,万分感谢!!! --------------------编程问答-------------------- http://wenku.baidu.com/link?url=nGUizQx0Xgp1nIftAr6FmGL2DZi_-psODgsH5-CHQ7fHW0CgPWTVDiT-46xajw5RZeV2_ZCcj3jbTPRKxEA5X8_zm5gIE7r22295puHmzIK --------------------编程问答--------------------
package reader;用这个试试。参考
import java.io.File;
import java.io.IOException;
import jxl.Cell;
import jxl.CellType;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
public class ReadExcel {
private String inputFile;
public void setInputFile(String inputFile) {
this.inputFile = inputFile;
}
public void read() throws IOException {
File inputWorkbook = new File(inputFile);
Workbook w;
try {
w = Workbook.getWorkbook(inputWorkbook);
// Get the first sheet
Sheet sheet = w.getSheet(0);
// Loop over first 10 column and lines
for (int j = 0; j < sheet.getColumns(); j++) {
for (int i = 0; i < sheet.getRows(); i++) {
Cell cell = sheet.getCell(j, i);
CellType type = cell.getType();
if (type == CellType.LABEL) {
System.out.println("I got a label "
+ cell.getContents());
}
if (type == CellType.NUMBER) {
System.out.println("I got a number "
+ cell.getContents());
}
}
}
} catch (BiffException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws IOException {
ReadExcel test = new ReadExcel();
test.setInputFile("c:/temp/lars.xls");
test.read();
}
}

JSP两行代码导出excel /word 笔记
在正常的展示列表页面添加两行代码即可导出excel 电子表格 :
html标签前加入如下代码:
<%@ page contentType="application/m易做图cel" %>
<!-- 以上这行设定本网页为excel格式的网页 -->
<%
response.setHeader("Content-disposition","inline; filename=agreement.xls");
//以上这行设定传送到前端浏览器时的档名为agreement.xls
//就是靠这一行,让前端浏览器以为接收到一个excel档
//导出Word只需要把contentType="application/m易做图cel"改为contentType="application/msword" ,filename=agreement.xls 改成 filename=agreement.doc
%>
格式化excel值:
用法:
在css中加入:mso-number-format定义数据格式,格式可以在excel中查看自定义格式,具体可以参考一下:
mso-number-format:"0" NO Decimals
mso-number-format:"0\.000" 3 Decimals
mso-number-format:"\#\,\#\#0\.000" Comma with 3 dec
mso-number-format:"mm\/dd\/yy" Date7
mso-number-format:"mmmm\ d\,\ yyyy" Date9
mso-number-format:"m\/d\/yy\ h\:mm\ AM\/PM" D -T AMPM
mso-number-format:"Short Date" 01/03/1998
mso-number-format:"Medium Date" 01-mar-98
mso-number-format:"d\-mmm\-yyyy" 01-mar-1998
mso-number-format:"Short Time" 5:16
mso-number-format:"Medium Time" 5:16 am
mso-number-format:"Long Time" 5:16:21:00
mso-number-format:"Percent" Percent - two decimals
mso-number-format:"0%" Percent - no decimals
mso-number-format:"0\.E+00" Scientific Notation
mso-number-format:"\@" Text
mso-number-format:"\#\ ???\/???" Fractions - up to 3 digits (312/943)
如果项目放到weblogic 服务器下 excel可以正常导出,但有时候会报“ Response already committed” 异常,原因可能是:
重复提交,在某个地方有submit等的信息
处理办法:可以使用类似 out.clear() 的语句来关闭某些流
用法:放置与最后一个html结束标签之后
实例代码 :

不知道是我人品问题还是怎么了滴,,,我试了一下这个,一运行直接报错。

首先保证你的查询列表可以正常展示 ,之后再添加那两行代码 ,我给你的就是原版的,测试通过的 --------------------编程问答-------------------- 根据pojo类的自省机制将excel模板中的数据读入到pojo类中,save保存 --------------------编程问答-------------------- 用poi吧,网上例子很多 --------------------编程问答-------------------- 我能给你个Excel工具类,把数组转换成excel的形式。
当然,具体还得需要你改改。。

对不起啊,上次太草率了点。这样确实可以导出文件,可能我哪里出了问题吧。文件倒是导出了,可是里面没数据。我在看看。。。 --------------------编程问答-------------------- 呵呵 严重了.......
