可以使用 Apache POI 库来读取 Excel 中的合并单元格数据。下面是一个示例代码,演示了如何读取合并单元格的数据:
```java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileInputStream;
import java.io.IOException;
public class ReadMergedCells {
public static void main(String[] args) {
try (FileInputStream fis = new FileInputStream("path/to/your/excel/file.xlsx");
Workbook workbook = new XSSFWorkbook(fis)) {
Sheet sheet = workbook.getSheetAt(0);
for (Row row : sheet) {
for (Cell cell : row) {
CellRangeAddress mergedRegion = getMergedRegion(sheet, cell.getRowIndex(), cell.getColumnIndex());
if (mergedRegion != null) {
int firstRow = mergedRegion.getFirstRow();
int firstColumn = mergedRegion.getFirstColumn();
Cell firstCell = sheet.getRow(firstRow).getCell(firstColumn);
System.out.println("Merged cell data: " + firstCell.getStringCellValue());
} else {
System.out.println("Cell data: " + cell.getStringCellValue());
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
private static CellRangeAddress getMergedRegion(Sheet sheet, int rowNum, int colNum) {
for (int i = 0; i < sheet.getNumMergedRegions(); i++) {
CellRangeAddress mergedRegion = sheet.getMergedRegion(i);
if (mergedRegion.isInRange(rowNum, colNum)) {
return mergedRegion;
}
}
return null;
}
}
```
请将 "path/to/your/excel/file.xlsx" 替换为你实际的 Excel 文件路径。这段代码会遍历所有单元格,如果单元格属于合并单元格,就获取合并单元格的第一个单元格,并打印其数据。如果不是合并单元格,则直接打印单元格的数据。
这样你就可以使用 Apache POI 读取合并单元格的数据了。希望对你有帮助!
