java 实现两个pdf文件 合并为一个pdf 文件

package test;

import java.io.FileOutputStream;

import com.lowagie.text.Document;

import com.lowagie.text.pdf.PdfCopy;

import com.lowagie.text.pdf.PdfImportedPage;

import com.lowagie.text.pdf.PdfReader;

/**

* @author Crazy.jia 不同pdf文件 合并

*/

String[] files = { "file:///C:/Users/Crazy.jia/Desktop/00.pdf","file:///C:/Users/Crazy.jia/Desktop/1.pdf" };

String savepath = "C:\\Users\\Crazy.jia\\Desktop\\temp.pdf";

mergePdfFiles(files, savepath);

} /*

* * 合並pdf文件 * * @param files 要合並文件數組(絕對路徑如{ "e:\\1.pdf", "e:\\2.pdf" ,

* "e:\\3.pdf"}) * @param newfile

* 合並後新產生的文件絕對路徑如e:\\temp.pdf,請自己刪除用過後不再用的文件請 * @return boolean

* 產生成功返回true, 否則返回false
