您可以使用Apache POI库来实现JavaFX中的Excel临时导出。Apache POI是一个流行的Java库,用于处理Microsoft Office文件,包括Excel文件。
首先,您需要在项目中添加Apache POI的依赖。您可以在Maven或Gradle中添加以下依赖项:
Maven:
```xml
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.0.0</version>
</dependency>
```
Gradle:
```groovy
implementation 'org.apache.poi:poi:5.0.0'
```
接下来,您可以使用以下代码示例将数据导出到Excel文件:
```java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileOutputStream;
import java.io.IOException;
public class ExcelExporter {
public static void exportDataToExcel(String[][] data, String filePath) throws IOException {
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
int rowCount = 0;
for (String[] rowData : data) {
Row row = sheet.createRow(rowCount++);
int columnCount = 0;
for (String cellData : rowData) {
Cell cell = row.createCell(columnCount++);
cell.setCellValue(cellData);
}
}
try (FileOutputStream outputStream = new FileOutputStream(filePath)) {
workbook.write(outputStream);
}
}
public static void main(String[] args) {
String[][] data = {
{"Name", "Age", "City"},
{"John", "25", "New York"},
{"Jane", "30", "London"},
{"Tom", "35", "Paris"}
};
try {
exportDataToExcel(data, "output.xlsx");
System.out.println("Data exported to Excel successfully.");
} catch (IOException e) {
System.out.println("Error exporting data to Excel: " + e.getMessage());
}
}
}
```
该示例代码创建了一个名为"Sheet1"的工作表,并将数据写入到Excel文件中。您可以根据需要调整数据数组和输出文件路径。最后,调用`exportDataToExcel`方法将数据导出到Excel文件中。
