java实现excel导入功能

方法一
/**
*使用Hibernate框架导入
* @throws IOException
* @throws BiffException
*/
public String imp() throws BiffException, IOException {
TYh user = (TYh) session.get(SSHConstant.ONLINE_USER);// 获取用户信息
//输入流  
InputStream fis = null;
try {
fis = new FileInputStream(excelName);
} catch (FileNotFoundException e) {
e.printStackTrace();
}  
//得到解析Excel的实体集合  
//打开文件
try {
Workbook book = Workbook.getWorkbook(fis);
//得到第一个工作表对象
Sheet sheet = book.getSheet(0);
//得到第一个工作表中的总行数
int rowCount = sheet.getRows();
//循环取出Excel中的内容
for (int i = 1; i < rowCount; i++) {
Cell[] cells = sheet.getRow(i);
YpLsgzry lsgz = new YpLsgzry();//new一个对象
lsgz.setLsgzryxm(cells[0].getContents());
lsgz.setLsgzryxb(cells[1].getContents());
lsgz.setLsgzrysfzh(cells[2].getContents());
lsgz.setLsgzryfl(cells[3].getContents());
lsgz.setLsgzryjf(cells[4].getContents());
lsgz.setLsgzrycphm(cells[5].getContents());
lsgz.setLsgzrygzyy(cells[6].getContents());
lsgz.setKsgzsj(cells[7].getContents());
lsgz.setJsgzsj(cells[8].getContents());
lsgz.setSqgzdw(cells[9].getContents());
lsgz.setSqrxm(cells[10].getContents());
lsgz.setSqrlxdh(cells[11].getContents());
lsgz.setJcf(cells[12].getContents());
lsgz.setGjf(cells[13].getContents());
lsgz.setLsgzryqttz(cells[14].getContents());
     service.saveOrUpdate(lsgz);
     logservice.savelogHadle(2, user.getYhm()+"导入", 1);//日志记录
}
} catch (BiffException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "add";

方法二
/**
*使用jdbc架导入
* @throws IOException
* @throws BiffException
*/

Cell cell = null;
InputStream stream = new FileInputStream(excelFileName);
rwb = Workbook.getWorkbook(stream);
Sheet sheet = rwb.getSheet(0);
// 行数(表头的目录不需要，从1开始)
for (int i = 1; i < sheet.getRows(); i++) {
String[] str = new String[sheet.getColumns()];
// 列数
for (int j = 0; j < sheet.getColumns(); j++) {
// 获取第i行，第j列的值
cell = sheet.getCell(j, i);
str[j] = cell.getContents();
}
// 把刚获取的列存入list
list.add(str);
}
return list;

}
