使用OpenOffice转换

前言：通过第三方工具openoffice，将word、excel、ppt等文件转换为pdf文件支持在线 预 览；官网地址：/download/

一、安装OpenOffice

提取码: xhdf

1、打开运行程序 这里是安装向导首界面 点击下一步按钮

2、点击浏览按钮 选择安装目录路径，输入使用的用户 以及选择用户权限 点击安装

如图所示

3、输入使用的用户 以及选择用户权限 点击下一步

4、这里勾选自定义安装，点击下一步，如果这里勾选的是 通常 会默认安装到c盘，如果是代码启动，目录要指定到c盘的

5、把用不到的功能禁用，并指定到同一目录下方便管理，点击下一步

6、继续下一步

7、安装完成

8、启动服务 打开cmd 切换到安装目录program下（如果组件安装选的是 通常，组件会安装到c盘

// 粘贴此命令soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

二、引入jar包

commons-cli-1.2.jar

commons-io-1.4.jar

jodconverter-2.2.2.jar

jodconverter-cli-2.2.2.jar

juh-3.0.1.jar

jurt-3.0.1.jar

ridl-3.0.1.jar

slf4j-api-1.5.6.jar

slf4j-jdk14-1.5.6.jar

unoil-3.0.1.jar

xstream-1.3.1.jar

三、创建工具类

public class OpenOfficeUtil {private static OpenOfficeUtil doc2HtmlUtil;/*** 获取Doc2HtmlUtil实例*/public static synchronized OpenOfficeUtil getDoc2HtmlUtilInstance() {if (doc2HtmlUtil == null) {doc2HtmlUtil = new OpenOfficeUtil();}return doc2HtmlUtil;}/*** 转换文件成html* @param inputStream* @param path 路径* @param type 文件类型* @return* @throws IOException */public String fileToHtml(InputStream inputStream, String path,String type) throws IOException {Date date = new Date();SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");String timesuffix = sdf.format(date);String docFileName =
