比较简单,直接看代码:
import java.io.File;import java.io.FileInputStream;import org.apache.poi.hssf.usermodel.HSSFCell;import org.apache.poi.hssf.usermodel.HSSFRow;import org.apache.poi.hssf.usermodel.HSSFSheet;import org.apache.poi.hssf.usermodel.HSSFWorkbook;public class PoiReadExcel { public static void readExcel(){ File f = new File("C:\\Documents and Settings\\Administrator\\桌面\\123.xls");try { FileInputStream is = new FileInputStream(f); HSSFWorkbook wbs = new HSSFWorkbook(is); HSSFSheet childSheet = wbs.getSheetAt(0); System.out.println("有行数1 :" + childSheet.getLastRowNum()); int j; for (j = 0; j <= childSheet.getLastRowNum(); j++) { HSSFRow row = childSheet.getRow(j);// System.out.println(row.getPhysicalNumberOfCells()); System.out.println("有列数" + row.getLastCellNum()); if (null != row) { for (int k = 0; k < row.getLastCellNum(); k++) { HSSFCell cell = row.getCell((short)k); if (null != cell) { switch (cell.getCellType()) { case HSSFCell.CELL_TYPE_NUMERIC: // 数字 System.out.print(cell.getNumericCellValue() + " "); break; case HSSFCell.CELL_TYPE_STRING: // 字符串 System.out.print(cell.getStringCellValue() + " "); break; case HSSFCell.CELL_TYPE_BOOLEAN: // Boolean System.out.println(cell.getBooleanCellValue() + " "); break; case HSSFCell.CELL_TYPE_FORMULA: // 公式 System.out.print(cell.getCellFormula() + " "); break; case HSSFCell.CELL_TYPE_BLANK: // 空值 System.out.println(" "); break; case HSSFCell.CELL_TYPE_ERROR: // 故障 System.out.println(" "); break; default: System.out.print("未知类型 "); break; } } else { System.out.print("- "); }// System.out.println(); } } System.out.println(); } System.out.println(); System.out.println("有行数2 " + childSheet.getLastRowNum()+"--"+j); } catch (Exception e) { e.printStackTrace(); }}}
