要在Java中将Excel转换为PDF,你可以使用Apache POI和iText库。这里是一个简单的示例代码:
```
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfWriter;
public class ExcelToPdfConverter {
public static void convert(String excelFilePath, String pdfFilePath) throws IOException {
// Load Excel file
Workbook workbook = WorkbookFactory.create(new File(excelFilePath));
// Create PDF document
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(pdfFilePath));
document.open();
// Convert each sheet in Excel file to PDF
for (int i = 0; i < workbook.getNumberOfSheets(); i++) {
document.newPage();
document.add(new com.itextpdf.text.Paragraph(workbook.getSheetName(i)));
document.add(new com.itextpdf.text.Paragraph("\n"));
document.add(createPdfTable(workbook.getSheetAt(i)));
}
// Close document and workbook
document.close();
workbook.close();
}
private static com.itextpdf.text.Table createPdfTable(org.apache.poi.ss.usermodel.Sheet sheet) {
com.itextpdf.text.Table table = new com.itextpdf.text.Table(sheet.getRow(0).getLastCellNum());
for (int i = 0; i < sheet.getLastRowNum() + 1; i++) {
org.apache.poi.ss.usermodel.Row row = sheet.getRow(i);
for (int j = 0; j < row.getLastCellNum(); j++) {
org.apache.poi.ss.usermodel.Cell cell = row.getCell(j);
String value = cell.getStringCellValue();
table.addCell(value);
}
}
return table;
}
}
```
这个代码将Excel文件中的每个工作表转换为PDF页面,并将它们合并在一起。你需要将Apache POI和iText库添加到你的Java项目中,以使此代码正常工作。
