首先机器要安装openoffice软件，下载链接：http://www.openoffice.org/download/index.html

学习结合网友写的，直接给出代码：

import java.io.File;
import java.io.IOException;
import java.util.Properties;import org.artofsolving.jodconverter.OfficeDocumentConverter;
import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;
import org.artofsolving.jodconverter.office.OfficeManager;/*** * <ul>* <li>日期：2015-11-16-上午10:22:11</li>* <li>创建人:lxz</li>* <li>jodconverter-3.0</li>* </ul>*/
public class Office2PdfUtil{private static Office2PdfUtil office2PdfUtil = new Office2PdfUtil();private static  OfficeManager officeManager;//openOffice安装路径private static String OPEN_OFFICE_HOME = "C:\\Program Files (x86)\\OpenOffice 4\\";//服务端口private static int OPEN_OFFICE_PORT[] = {8100};public static Office2PdfUtil getOffice2PdfUtil() {return office2PdfUtil;}/*** * office2Pdf 方法* @descript：TODO* @param inputFile 文件全路径* @param pdfFilePath pdf文件全路径* @return void* @author lxz* @return */    private void office2Pdf(String inputFile,String pdfFilePath) {File pdfFile = new File(pdfFilePath);if (pdfFile.exists()) {pdfFile.delete();}try{long startTime = System.currentTimeMillis();//打开服务startService();        OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);//开始转换converter.convert(new File(inputFile),new File(pdfFilePath));//关闭stopService();System.out.println("运行结束");}catch (Exception e) {// TODO: handle exceptione.printStackTrace();}}public static void stopService(){if (officeManager != null) {officeManager.stop();}}public static void startService(){DefaultOfficeManagerConfiguration configuration = new DefaultOfficeManagerConfiguration();try {configuration.setOfficeHome(OPEN_OFFICE_HOME);//设置安装目录configuration.setPortNumbers(OPEN_OFFICE_PORT); //设置端口configuration.setTaskExecutionTimeout(1000 * 60 * 5L);configuration.setTaskQueueTimeout(1000 * 60 * 60 * 24L);officeManager = configuration.buildOfficeManager();officeManager.start();    //启动服务} catch (Exception ce) {System.out.println("office转换服务启动失败!详细信息:" + ce);}}
}

需要引入jodconverter-core-3.0-beta-4.jar及其相关包。
