問題描述
我怎么能轉換/保存 Excel中文件復制到 PDF ？我使用的java游戲框架來產生一些 Excel中文件，現在要求修改 PDF 。我不想再code一切。
有沒有辦法轉換為 PDF ？
我生成的 Excel中文件是從模板;我讀的Excel模板文件，寫入更改，然后保存為新的Excel文件。這樣一來，該模板是不變的。它包含邊框，圖像和其他格式。

您將需要以下Java庫和相關的JAR文件的程序協同工作。
POI V3.8
iText的v5.3.4
試用此例為XLS轉換為PDF
在完整的Java code，接受Excel的小號preadsheet數據作為輸入和轉換是一個PDF表格數據表示如下：
import java.io.FileInputStream; import java.io.*; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.ss.usermodel.*; import java.util.Iterator; import com.itextpdf.text.*; import com.itextpdf.text.pdf.*; public class excel2pdf { public static void main(String[] args) throws Exception{ FileInputStream input_document = new FileInputStream(new File("C:\\excel_to_pdf.xls")); // Read workbook into HSSFWorkbook HSSFWorkbook my_xls_workbook = new HSSFWorkbook(input_document); // Read worksheet into HSSFSheet HSSFSheet my_worksheet = my_xls_workbook.getSheetAt(0); // To iterate over the rows Iterator<Row> rowIterator = my_worksheet.iterator(); //We will create output PDF document objects at this point Document iText_xls_2_pdf = new Document(); PdfWriter.getInstance(iText_xls_2_pdf, new FileOutputStream("Excel2PDF_Output.pdf")); iText_xls_2_pdf.open(); //we have two columns in the Excel sheet, so we create a PDF table with two columns //Note: There are ways to make this dynamic in nature, if you want to. PdfPTable my_table = new PdfPTable(2); //We will use the object below to dynamically add new data to the table PdfPCell table_cell; //Loop through rows. while(rowIterator.hasNext()) { Row row = rowIterator.next(); Iterator<Cell> cellIterator = row.cellIterator(); while(cellIterator.hasNext()) { Cell cell = cellIterator.next(); //Fetch CELL switch(cell.getCellType()) { //Identify CELL type //you need to add more code here based on //your requirement / transformations case Cell.CELL_TYPE_STRING: //Push the data from Excel to PDF Cell table_cell=new PdfPCell(new Phrase(cell.getStringCellValue())); //feel free to move the code below to suit to your needs my_table.addCell(table_cell); break; } //next line } } //Finally add the table to PDF document iText_xls_2_pdf.add(my_table); iText_xls_2_pdf.close(); //we created our pdf file.. input_document.close(); //close xls } }
我希望這會幫助你。
