java利用poi和jfinal框架将excel导入数据库

public void imports() throws Exception {
File file = new File("C://20171024125408.xls");
HSSFWorkbook book = new HSSFWorkbook(new FileInputStream(file));
HSSFSheet sheet = book.getSheetAt(0);
// 里面有多少行
int rows = sheet.getLastRowNum();
for (int i = 1; i <= rows; i++) {// 从1开始是去除首行-头
HSSFRow row = sheet.getRow(i);// 行数
String num = row.getCell(0).getStringCellValue();// 某行0列
String name = row.getCell(1).getStringCellValue();// 某行1列
Record record = new Record();
record.set("num", num);
record.set("name", name);
boolean boo = Db.save("hzztest", record);
}
renderJson(rows);

}

上述为office2003，若为office2007，则应使用以下方法

public static void main(String[] args) throws Exception {
FileInputStream in = new FileInputStream(new File("E:\\a\\jns.xlsx"));
Workbook wb = null;
wb = new XSSFWorkbook(in);
in.close();
wb.close();
// 创建工作表sheet
Sheet sheet = wb.getSheetAt(0);
// 获取sheet中数据的行数
int rows = sheet.getPhysicalNumberOfRows();
System.out.println("total rows" + rows);
boolean boo = sheet.getRow(1).getCell(0).getBooleanCellValue();
String st = sheet.getRow(1).getCell(1).getStringCellValue();
double num = sheet.getRow(1).getCell(2).getNumericCellValue();
Date date = sheet.getRow(1).getCell(3).getDateCellValue();
System.out.println(boo+":String:"+st+":double:"+num+":date:"+date);

}

所需jar包

若是遇到，Cannot get a STRING value from a NUMERIC cell

则先设置单元格类型为String---sheet.getRow(j).getCell(2).setCellType(CellType.STRING);
