获取逻辑行
Workbook wb = null;
Sheet sheet = wb.getSheetAt(0);
Row row = sheet.getRow(r);
判断隐藏行和隐藏列
row.getZeroHeight() //判断隐藏行
sheet.isColumnHidden(j) //判断隐藏列
遍历单元格
//遍历行
for (int r = 0; r <= sheet.getPhysicalNumberOfRows(); r++) {
Row row = sheet.getRow(r);
if(row.getZeroHeight()){
System.out.println("第"+(r + 1)+"行隐藏行");
continue;
}
//遍历列
for (int j = 0; j < row.getPhysicalNumberOfCells(); j++) {
if (sheet.isColumnHidden(j)){
System.out.println("第" + j + "列隐藏列");
continue;
}
//获取单元格的值
String value = checkValue(r,j,row);
}
}
获取单元格值-数据处理util
public static String checkValue(int r, int j, Row row) {
Cell cell = row.getCell(j);
String value = null;
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
if(cell == null){
cell = row.createCell(0);
cell.setCellValue("");
}
try {
switch (cell.getCellType()){
case Cell.CELL_TYPE_STRING:
value = cell.getStringCellValue().trim();
break;
case Cell.CELL_TYPE_BOOLEAN:
value = String.valueOf(cell.getBooleanCellValue());
break;
case Cell.CELL_TYPE_FORMULA:
//处理数字和公式
value = String.valueOf(Double.valueOf(cell.getNumericCellValue()));
value = value.replaceAll("0+?$", "");
value = value.replaceAll("[.]$", "");
break;
case Cell.CELL_TYPE_NUMERIC:
//处理日期格式的Excel数据
if (HSSFDateUtil.isCellDateFormatted(cell)) {
Date date = cell.getDateCellValue();
value = sdf.format(date);
} else {
//处理科学计数法
double temp = cell.getNumericCellValue();
DecimalFormat df = new DecimalFormat("0");
value = df.format(temp);
}
break;
default:
return "";
}
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("导入失败!第"+(i + 1)+"行第"+(j + 1)+"列,格式有误 ");
}
return value;
}
拓展：

获取单元格格式和对应的值获取
单元格类型 数值类型和java类型 取值（Cell.getCellType()）
文本 1 / CELL_TYPE_STRING cell.getStringCellValue()
公式 2 / CELL_TYPE_FORMULA cell.getNumericCellValue())
数值 0 / CELL_TYPE_NUMERIC cell.getNumericCellValue()
布尔 4 / CELL_TYPE_BOOLEAN cell.getBooleanCellValue()
日期 0 / CELL_TYPE_NUMERIC cell.getDateCellValue()
异常 5 / CELL_TYPE_ERROR cell.getErrorCellValue()
