java读取遍历excel

java通过poi方式读取excel文件

适用于.xlsx格式，如果是xls可以先将xls转换成xlsx

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

String filePath = "C:\\Users\\1606020155.xlsx";
InputStream is = new FileInputStream(filePath);
XSSFWorkbook wb = new XSSFWorkbook(is);
XSSFSheet sheet = wb.getSheetAt(0);
Row row=sheet.getRow(2);
Cell cell=row.getCell(3);
System.out.println(cell.getDateCellValue());

for(int i=0;i<sheet.getLastRowNum();i++){
Row row=sheet.getRow(i);
System.out.println(row.getCell(0).getDateCellValue());
}
