使用PDFBOX API創建一個新的PDF文檔

Question

我需要創建一個PDF，它將保存執行狀態的報告，其狀態將在表結構中。使用PDFBOX API可以生成pdf表格格式嗎？

以下是創建一個新的PDF文檔一些示例代碼：

import java.awt.Color; 
import java.io.IOException; 
import org.apache.pdfbox.exceptions.COSVisitorException; 
import org.apache.pdfbox.pdmodel.PDDocument; 
import org.apache.pdfbox.pdmodel.PDPage; 
import org.apache.pdfbox.pdmodel.edit.PDPageContentStream; 
import org.apache.pdfbox.pdmodel.font.PDFont; 
import org.apache.pdfbox.pdmodel.font.PDType1Font; 



public class HelloWorld 
{ 
    /** 
    * Constructor. 
    */ 
    public HelloWorld() 
    { 
     super(); 
    } 


    public static void main(String[] args) throws IOException, COSVisitorException 
    { 
     PDDocument doc = null; 
    try 
    { 
     doc = new PDDocument(); 

     PDPage page = new PDPage(); 
     doc.addPage(page); 
     PDFont font = PDType1Font.COURIER_BOLD_OBLIQUE; 
     Color color = Color.blue; 


     PDPageContentStream contentStream = new PDPageContentStream(doc, page); 
     contentStream.beginText(); 
     contentStream.setFont(font, 12); 
     contentStream.setNonStrokingColor(color); 
     contentStream.moveTextPositionByAmount(100, 700); 
     contentStream.drawString("message"); 

     contentStream.setNonStrokingColor(Color.GREEN); 
     contentStream.drawString("Hi"); 

     contentStream.endText(); 
     contentStream.close(); 
     doc.save("d:\\abc.pdf"); 
    } 
    finally 
    { 
     if(doc != null) 
     { 
      doc.close(); 
     } 
    } 
    } 
}

試試這個：

public static void drawTable(PDPage page, PDPageContentStream contentStream, 
          float y, float margin, 
          String[][] content) throws IOException { 
     final int rows = content.length; 
     final int cols = content[0].length; 
     final float rowHeight = 20f; 
     final float tableWidth = page.getCropBox().getWidth() - margin - margin; 
     final float tableHeight = rowHeight * rows; 
     final float colWidth = tableWidth/(float)cols; 
     final float cellMargin=5f; 

     //draw the rows 
     float nexty = y ; 
     for (int i = 0; i <= rows; i++) { 
      contentStream.drawLine(margin, nexty, margin+tableWidth, nexty); 
      nexty-= rowHeight; 
     } 

     //draw the columns 
     float nextx = margin; 
     for (int i = 0; i <= cols; i++) { 
      contentStream.drawLine(nextx, y, nextx, y-tableHeight); 
      nextx += colWidth; 
     } 

     //now add the text 
     contentStream.setFont(PDType1Font.HELVETICA_BOLD , 12); 

     float textx = margin+cellMargin; 
     float texty = y-15; 
     for(int i = 0; i < content.length; i++){ 
      for(int j = 0 ; j < content[i].length; j++){ 
       String text = content[i][j]; 
       contentStream.beginText(); 
       contentStream.moveTextPositionByAmount(textx,texty); 
       contentStream.drawString(text); 
       contentStream.endText(); 
       textx += colWidth; 
      } 
      texty-=rowHeight; 
      textx = margin+cellMargin; 
     } 
    } 

，只需調用此方法main功能

public static void main(String[] args) throws IOException, COSVisitorException { 
    PDDocument doc = new PDDocument(); 
    PDPage page = new PDPage(); 
    doc.addPage(page); 
    PDPageContentStream contentStream = new PDPageContentStream(doc, page); 

    String[][] content = { 
     {"Name"," Time "}, 
     {"HTC","01:25"}, 
     {"Samsung Tab2","05:30"} 
    } ; 

    drawTable(page, contentStream, 700, 100, content); 

    contentStream.close(); 
    doc.save("h:\\test.pdf"); 
}

我只是廣告ded pdfBOX或github的簡單包裝。它有一個簡單的表格支持，你可能可以用作cut'n粘貼基線。或者，如果你願意的話，也可以使用課程。 https://github.com/heksemann/HexPDF
