java合并pdf

一.开发准备

下载pdfbox-app-1.7.1.jar包;下载地址：http://download.****.net/detail/yanning1314/4852276

二.简单小例子

在开发中在根据实际情况进行修改，下面是主要API的应用

package com.shine.efcms.struts;
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.util.PDFMergerUtility;  

public class test {  

  private static String[] getFiles(String folder) throws IOException {
      File _folder = new File(folder);
      String[] filesInFolder;     

      if(_folder.isDirectory()){
            filesInFolder = _folder.list();
            return filesInFolder;
       } else {
            throw new IOException("Path is not a directory");
       }
    }  

    public static void main(String[] args) throws Exception {  

        //pdf合并工具类
        PDFMergerUtility mergePdf = new PDFMergerUtility();  

        String folder = "F:/test";
        String destinationFileName = "mergedTest.pdf";  

        String[] filesInFolder = getFiles(folder);     

        for(int i = 0; i < filesInFolder.length; i++){
            //循环添加要合并的pdf存放的路径
            mergePdf.addSource(folder + File.separator + filesInFolder[i]);
        }  

        //设置合并生成pdf文件名称
        mergePdf.setDestinationFileName(folder + File.separator + destinationFileName);
        //合并pdf
        mergePdf.mergeDocuments();
    }  

}
