首先機器要安裝openoffice軟體，下載連結：http://www.openoffice.org/download/index.html

學習結合網友寫的，直接給出程式碼：

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;

    private void office2Pdf(String inputFile,String pdfFilePath) {
        
        File pdfFile = new File(pdfFilePath);

    public static void startService(){
        DefaultOfficeManagerConfiguration configuration = new DefaultOfficeManagerConfiguration();
        try {
            configuration.setOfficeHome(OPEN_OFFICE_HOME);//設定安裝目錄
            configuration.setPortNumbers(OPEN_OFFICE_PORT); //設定埠
            configuration.setTaskExecutionTimeout(1000 * 60 * 5L);
            configuration.setTaskQueueTimeout(1000 * 60 * 60 * 24L);
            officeManager = configuration.buildOfficeManager();
            officeManager.start();    //啟動服務
        } catch (Exception ce) {
            System.out.println("office轉換服務啟動失敗!詳細資訊:" + ce);

需要引入jodconverter-core-3.0-beta-4.jar及其相關包。
