第一次写博客，一个刚刚入行Java开发的小白，只是希望能把自己平时遇到的问题和解决方法分享给遇到同样问题的人，肯定会有不足的地方，如果大佬们看到希望能多多指正，谢谢啦

pdf转换word

用到的jar是pdfbox

String pdfFile = "C:/Users/FengJQ/Desktop/****.pdf"; PDDocument doc = PDDocument.load(new File(pdfFile)); int pagenumber = doc.getNumberOfPages(); pdfFile = pdfFile.substring(0, pdfFile.lastIndexOf(".")); String fileName = pdfFile + ".doc"; File file = new File(fileName); if (!file.exists()) { file.createNewFile(); } FileOutputStream fos = new FileOutputStream(fileName); Writer writer = new OutputStreamWriter(fos, "UTF-8"); PDFTextStripper stripper = new PDFTextStripper(); stripper.setSortByPosition(true);// 排序 stripper.setStartPage(1);// 设置转换的开始页 stripper.setEndPage(pagenumber);// 设置转换的结束页 stripper.writeText(doc, writer); writer.close(); doc.close();

word转pdf

有两种方法，一种是利用jacob架包，一种是OpenOffice软件

第一种，利用jacob架包

/** * * @param source 要转换的word文件 * @param target 要转换成为的pdf文件 * @return */ public static boolean word2pdf(String source, String target) { System.out.println("Word转PDF开始启动..."); long start = System.currentTimeMillis(); ActiveXComponent app = null; try { app = new ActiveXComponent("Word.Application"); app.setProperty("Visible", false); Dispatch docs = app.getProperty("Documents").toDispatch(); System.out.println("打开文档：" + source); Dispatch doc = Dispatch.call(docs, "Open", source, false, true).toDispatch(); System.out.println("转换文档到PDF：" + target); File tofile = new File(target); if (tofile.exists()) { tofile.delete(); } Dispatch.call(doc, "SaveAs", target, wdFormatPDF); Dispatch.call(doc, "Close", false); long end = System.currentTimeMillis(); System.out.println("转换完成，用时：" + (end - start) + "ms"); return true; } catch (Exception e) { System.out.println("Word转PDF出错：" + e.getMessage()); return false; } finally { if (app != null) { app.invoke("Quit", wdDoNotSaveChanges); } } }

第二种方法，，需要先安装openoffice软件

/** * @param dirs doc转换文件夹，批量转换 */ public static void word2Pdf(String dirs){ File dir = new File(dirs); File[] files = dir.listFiles(new WordFilenameFilter()); //遍历文件夹方式 if (files == null||files.length==0){ throw new NullPointerException("该路径下没有doc文件或者docx文件"); } for (int i = 0; i < files.length; i++) { String strFileName = files[i].getAbsolutePath().toLowerCase(); TestThread t1 = new WordToPDF.TestThread(); //输入文件名 t1.setInputFile(new File(strFileName)); //获得“.”前面的文件名并将其输入为PDF t1.setOutputFile(new File(strFileName.substring(0,strFileName.indexOf("."))+".pdf")); t1.start(); } } /** * @param orgfileName 原始的word文件名 * @param descFileName 生成的pdf文件名 */ public static void word2Pdf(String orgfileName, String descFileName) { if(!isWord(orgfileName)||descFileName==null){ throw new IllegalArgumentException("原始word文件名不是word文档，或者descFileName为空"); }else{ TestThread t1 = new WordToPDF.TestThread(); // 输入文件名 t1.setInputFile(new File(orgfileName)); // 获得"."前面的文件名并将其输入为PDF t1.setOutputFile(new File(descFileName.substring(0, descFileName .indexOf(".")) + ".pdf")); t1.start(); } } static class WordFilenameFilter implements FilenameFilter{ @Override //只转换word文档 public boolean accept(File dir, String name) { return isWord(name); } } /** * @param name 文件名 * @return 判断是否为doc或者word文档 */ private static boolean isWord(String name){ return name.endsWith(".doc")||name.endsWith(".docx"); //return true; } util public class WordToPDF { public void docToPdf(File inputFile, File outputFile) { // 启动服务 String OpenOffice_HOME = "E:/Program Files (x86)/OpenOffice 4";//这里是OpenOffice的安装目录 if (OpenOffice_HOME.charAt(OpenOffice_HOME.length() - 1) != '/') { OpenOffice_HOME += "/"; } Process pro = null; OpenOfficeConnection connection = null; // 启动OpenOffice的服务 String command = OpenOffice_HOME + "program/soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\""; // connect to an OpenOffice.org instance running on port 8100 try { pro = Runtime.getRuntime().exec(command); connection = new SocketOpenOfficeConnection(8100); connection.connect(); // convert DocumentConverter converter = new OpenOfficeDocumentConverter(connection); System.out.println(inputFile + "=" + outputFile); converter.convert(inputFile, outputFile); } catch (Exception ex) { System.out.println("启动OpenOffice的服务"); ex.printStackTrace(); } finally { // close the connection if (connection != null) { connection.disconnect(); connection = null; } pro.destroy(); } System.out.println("生成: " + outputFile.getName()); } // 生产pdf线程 static class TestThread extends Thread { private File inputFile; private File outputFile; public void run() { WordToPDF t = new WordToPDF(); t.docToPdf(inputFile, outputFile); System.out.println(outputFile.getName() + "文件已生成"); } public void setInputFile(File inputFile) { this.inputFile = inputFile; } public void setOutputFile(File outputFile) { this.outputFile = outputFile; } } }
