1.JODConverter介绍：
JODConverter automates conversions between office document formats using or LibreOffice.
Supported formats include OpenDocument, PDF, RTF, HTML, Word, Excel, PowerPoint, and Flash.
It can be used as a Java library, a command line tool, or a web application.
JODConverter可以将一般格式的文档转换为PDF格式。

2.示例
这里用的是3.0的版本
OfficeManager officeManager = new DefaultOfficeManagerConfiguration().buildOfficeManager();officeManager.start();OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);converter.convert(new File("test.odt"), new File("test.pdf");officeManager.stop();
如果你直接运行这些代码的话，是不会成功的，报一个错误
Exception in thread "main" java.lang.IllegalStateException: officeHome not set and could not be auto-detectedat org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration.buildOfficeManager(DefaultOfficeManagerConfiguration.java:163)at org.ygy.util.PDFUtil.toPDF(PDFUtil.java:11)at org.ygy.util.PDFUtil.main(PDFUtil.java:21)
要使用JODconverter需要安装OpenOffice或者LibreOffice，我安装了OpenOffice。
然后设置一下officeHome：
public static void toPDF() {OfficeManager officeManager = new DefaultOfficeManagerConfiguration().setOfficeHome("D:\\program files\\ 3").buildOfficeManager();officeManager.start();OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);converter.convert(new File("E:\\demo.doc"), new File("E:\\demo_1.pdf"));officeManager.stop();}
这下就可以了，之前用2.2的版本，需要手动的开一个服务：
public static void startServer() {String cmd = "cmd /k soffice -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\" -nofirststartwizard";try {Runtime.getRuntime().exec(cmd , null , new File("D:\\program files\\ 3\\program"));} catch (IOException e) {e.printStackTrace();}}
3.TXT转换为PDF
在将.txt文件转换为PDF的时候发现，如果TXT文件的编码是ANSI的话，中文会产生乱码，解决办法是先将.txt保存为.odt文件,再将.odt文件转换为PDF就可以了。
如果TXT文件的编码是UTF-8的话，中文也可以正常转换。
package org.ygy.util;import java.io.File;import org.artofsolving.jodconverter.OfficeDocumentConverter;import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;import org.artofsolving.jodconverter.office.OfficeManager;public class PDFUtil {public static void toPDF(String sourcePath , String targetpath) {if(sourcePath.endsWith(".txt")) {//先保存为.odtStringBuffer odtPath = new StringBuffer(sourcePath.substring(0 , sourcePath.lastIndexOf(".")));odtPath.append(".odt");FileUtil.write(sourcePath , odtPath.toString());sourcePath = odtPath.toString();}OfficeManager officeManager = new DefaultOfficeManagerConfiguration().setOfficeHome("D:\\program files\\ 3").buildOfficeManager();officeManager.start();OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);converter.convert(new File(sourcePath), new File(targetpath));officeManager.stop();}public static void main(String[] args) {PDFUtil.toPDF("E:\\type.txt" , "E:\\type_2.pdf");}}
这篇博客还介绍了其他的转换PDF的方法，可以学习一下
