Workbook.cloneSheet() 未复制图表

是的,`Workbook.cloneSheet()` 方法在复制工作表时不会复制图表,只会复制工作表中的单元格和格式。如果要复制图表,可以使用 Apache POI 提供的 `Drawing` 对象和 `Chart` 对象。
以下是一个简单的示例代码,演示如何复制工作表的图表:
```java
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Drawing;
import org.apache.poi.ss.usermodel.ClientAnchor;
import org.apache.poi.ss.usermodel.Chart;
import org.apache.poi.ss.usermodel.ChartFactory;
import org.apache.poi.ss.usermodel.ChartData;
import org.apache.poi.ss.usermodel.ChartLegend;
import org.apache.poi.ss.usermodel.ChartTitle;
import org.apache.poi.ss.usermodel.DataFormat;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.VerticalAlignment;
public class CopySheetWithChartExample {
public static void main(String[] args) throws Exception {
String inputFile = "input.xlsx";
String outputFile = "output.xlsx";
int sheetIndexToCopy = 0;
int sheetIndexToInsert = 1;
// 读取输入文件
FileInputStream inputStream = new FileInputStream(inputFile);
Workbook inputWorkbook = WorkbookFactory.create(inputStream);
Sheet sheetToCopy = inputWorkbook.getSheetAt(sheetIndexToCopy);
// 创建输出文件
Workbook outputWorkbook = WorkbookFactory.create(true);
Sheet sheetToInsert = outputWorkbook.createSheet();
// 复制工作表
int rowCount = sheetToCopy.getLastRowNum();
for (int i = 0; i <= rowCount; i++) {
Row row = sheetToCopy.getRow(i);
Row newRow = sheetToInsert.createRow(i);
int cellCount = row.getLastCellNum();
for (int j = 0; j < cellCount; j++) {
newRow.createCell(j).setCellValue(row.getCell(j).getStringCellValue());
}
}
// 复制图表
Drawing<?> drawing = sheetToCopy.createDrawingPatriarch();
for (int i = 0; i < drawing.getCharts().size(); i++) {
Chart chartToCopy = drawing.getCharts().get(i);
ChartData dataToCopy = chartToCopy.getChartData();
ClientAnchor anchor = chartToCopy.getAnchor();
byte[] bytes = dataToCopy.getWorkbook().getBytes();
ChartData newData = new ChartData(bytes);
Chart newChart = ChartFactory.createChart(drawing, anchor, null, newData, true);
newChart.setTitle(chartToCopy.getTitle());
newChart.setLegend(chartToCopy.getLegend());
// 设置图表样式
newChart.getChartTitle().setOverlay(false);
newChart.getLegend().setOverlay(false);
newChart.getLegend().setPosition(ChartLegend.LegendPosition.BOTTOM);
newChart.getLegend().setHorizontalAlignment(HorizontalAlignment.CENTER);
newChart.getLegend().setVerticalAlignment(VerticalAlignment.BOTTOM);
DataFormat format = outputWorkbook.createDataFormat();
newChart.getPlotArea().getAxes().get(0).getNumberFormat().setDataFormat(format.getFormat("#,##0.00"));
// 将新图表插入工作表
outputWorkbook.setSheetName(sheetIndexToInsert, sheetToCopy.getSheetName());
outputWorkbook.setSheetOrder(sheetToCopy.getSheetName(), sheetIndexToInsert);
}
// 保存输出文件
FileOutputStream outputStream = new FileOutputStream(outputFile);
outputWorkbook.write(outputStream);
outputStream.close();
}
}
```
在这个示例中,我们首先复制工作表的单元格和格式,然后使用 `Drawing.getCharts()` 方法获取工作表中的所有图表。对于每个图表,我们复制其 `ChartData` 对象,然后使用 `ChartFactory.createChart()` 方法创建一个新的图表。我们还复制了图表的标题和图例,并设置了一些图表样式。最后,我们将新图表插入到输出工作簿的新工作表中,并将其保存到名为 `output.xlsx` 的文件中。
