java利用pdfbox+poi往pdf插入数据

2 .实现方法

/**from fhadmin.cn

  * 指定页码插入页

  * @param filename1  源pdf路径

  * @param filename2  需要插入的pdf路径

  * @param number     插入的页码

  * @param newfilename   全新pdf的路径

  * @throws Exception

  */

public void insertPage(String filename1,String filename2, int number,String newfilename,String tempPath) throws Exception {

     PDDocument pdf1 = PDDocument.load( new File(filename1));

     PDDocument pdf2 = PDDocument.load( new File(filename2));

     //1、将第一个pdf按页码全部拆开

     Splitter splitter = new Splitter();

     List<PDDocument> Pages = splitter.split(pdf1);

     Iterator<PDDocument> iterator = Pages.listIterator();

     PDFMergerUtility PDFmerger = new PDFMergerUtility();

     int i = 1 ;

     while (iterator.hasNext()) {

         if (i==number){

             System.out.println( "当前插入页码：" +number);

             pdf2.save(tempPath+ "/" + i + ".pdf" );

             i++;

         }

         PDDocument pd = iterator.next();

         String tempFile = tempPath+ "/" + i + ".pdf" ;

         System.out.println( "开始拆分:" +tempFile);

         pd.save(tempFile);

         i++;

     }

     //2、开始重组

     PDFmerger.setDestinationFileName(newfilename);

     //上面的i最后多加了一次，这里不取等

     for ( int j= 1 ;j<i;j++){

         String tempFile = tempPath+ "/" + j + ".pdf" ;

         System.out.println( "开始合并:" +tempFile);

         PDFmerger.addSource(tempFile);

     }

     //合并文档

     PDFmerger.mergeDocuments();

     System.out.println( "文档合并完成" );

     pdf1.close();

     pdf2.close();

}

3 .测试

//from fhadmin.cn

@Test

void insertPage() throws Exception {

     PdfUtils pdfUtils = new PdfUtils();

     String filename1 = "F:\\Users\\admin\\Desktop\\A.pdf" ;

     String filename2 = "F:\\Users\\admin\\Desktop\\B.pdf" ;

     String newfilename = "F:\\Users\\admin\\Desktop\\newA.pdf" ;

     String tempPath = "F:\\Users\\admin\\Desktop\\temp" ;

     int insertNum = 32 ;

     pdfUtils.insertPage(filename1,filename2,insertNum,newfilename,tempPath);

}
