有关于OpenOffice实现在线预览和编辑问题

某日，直属上级说：你去了解一下OpenOffice周三搞明白，然后我就开始看这方面的文档。总结一下踩到的坑和一些经验吧。

1、下载

​ 去官网上可以看到最新的版本是4.7.1了，下载就好了，默认安装路径：C:\Program Files (x86)\OpenOffice 4\program 然后傻瓜安装就可以，这个路径代码中多次会用到，注意留意。

2、cmd

​ 在javaWeb中使用的话需要打开相关服务端口，简单，win+R cmd 逐行输入就好了，下面是命令：

//进入目录
cd C:\Program Files (x86)\OpenOffice 4\program

//执行
soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

//查看是否启动成功
netstat -ano|findstr "8100"

出现端口信息127.0.0.1 8100什么的即可

3、代码

​ 不多说，代码附下(某位大神代码)：

import org.apache.commons.io.FilenameUtils;
import org.apache.log4j.Logger;
import org.artofsolving.jodconverter.OfficeDocumentConverter;
import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;
import org.artofsolving.jodconverter.office.ExternalOfficeManagerConfiguration;
import org.artofsolving.jodconverter.office.OfficeException;
import org.artofsolving.jodconverter.office.OfficeManager;

import java.io.File;
import java.util.Scanner;

public class ChangePDF {
    private static final Logger logger = Logger.getLogger(ChangePDF.class.getName());

    //OpenOffice安装路径，默认是 C:/Program Files (x86)/OpenOffice 4/
    private static String officeHome = "C:\\Program Files (x86)\\OpenOffice 4\\";

    //windows系统默认开启端口号8100
    @SuppressWarnings("static-access")
    private static int port = 8100;

    //连接服务器
    private static OfficeManager officeManager;
    private static boolean reconnect() {
        try {
            ExternalOfficeManagerConfiguration externalProcessOfficeManager = new ExternalOfficeManagerConfiguration();
            externalProcessOfficeManager.setConnectOnStart(true);
            externalProcessOfficeManager.setPortNumber(8100);
            officeManager = externalProcessOfficeManager.buildOfficeManager();
            officeManager.start();
            return true;
        } catch (OfficeException e) {
            e.printStackTrace();
            return false;
        }
    }

    //开启新的OpenOffice进程
    private static void start() {
//        logger.debug("启动OpenOffice服务");
        logger.debug("启动OpenOffice服务");
        try {
            DefaultOfficeManagerConfiguration configuration = new DefaultOfficeManagerConfiguration();
            configuration.setOfficeHome(officeHome);//安装地址
            configuration.setPortNumbers(port);//端口
            configuration.setTaskExecutionTimeout(1000 * 60 * 5);//设置任务执行超时5min
            configuration.setTaskQueueTimeout(1000 * 60 * 60 * 24);//设置任务队列超时24h
            officeManager = configuration.buildOfficeManager();
            officeManager.start();
        } catch (NullPointerException e) {
            e.printStackTrace();
            logger.error("启动OpenOffice服务出错" + e);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
            logger.error("启动OpenOffice服务出错" + e);
        } catch (IllegalStateException e) {
            e.printStackTrace();
            logger.error("启动OpenOffice服务出错" + e);
        } catch (OfficeException e) {
            e.printStackTrace();
            logger.error("启动OpenOffice服务出错" + e);
        }
    }

    //关闭进程
    private static void stop() {
        logger.debug("关闭OpenOffice服务");
        try {
            if (officeManager != null) {
                officeManager.stop();
            }
        } catch (OfficeException e) {
            e.printStackTrace();
            logger.error("关闭OpenOffice服务出错" + e);
        }
    }

    //1.PPT/ --> PDF
    public static File convertToPdf(String input){
        File inputFile = null;
        File outFile = null;
        //服务异常就开启新服务
        try {
            if (!reconnect()){
                start();
            }
            //FilenameUtils.separatorsToSystem：转换分隔符为当前系统分隔符
            // FilenameUtils.getFullPath:获取文件的完整目录
            // FilenameUtils.getBaseName:取出文件目录和后缀名的文件名
            String output = FilenameUtils.separatorsToSystem(FilenameUtils.getFullPath(input) + FilenameUtils.getBaseName(input) + ".pdf");
            inputFile = new File(input);
            outFile = new File(output);
            logger.info("开始转换文档：" + input + "==>" + output);
            OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
            converter.convert(inputFile,outFile);
        } catch (OfficeException e) {
            e.printStackTrace();
            logger.error("转换文档出错：" + e);
            outFile = null;
        }finally {
            logger.info("结束转换文档。");
            stop();
        }
        return outFile;
    }


    public static void main(String[] args) {
    //1
        Scanner sc = new Scanner(System.in);
        System.out.println("请输入所需浏览的文件路径和文件名：");
        String s = sc.nextLine();
        ChangePDF.convertToPdf(s);
	//2
//    ChangePDF.convertToPdf("G:\\DataText\\OpenOff\\A.ppt");

    }
}

4、配置pom文件

有些你可能用不到，但是可以导自己库中以后也省事了

5、预览PDF

要使用pdf.js技术，可以在我提供链接下载源码

1、将pdfjs文件夹放在项目webapp下

2、创建html文档，设置好自己的路径

<html lang="zh-CN">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<input type="button" onclick="openPDF()" value="预览文件"/>
<script>
    function openPDF(){
        var url="/OpenOff/src/main/webapp/A.pdf";
        window.open("pdfjs/web/viewer.html?file=" + url);
    }
script>
body>
html>

6、代码上传

代码在连接上，但是前后台的响应还没有实现，大家先看主体部分吧。

7、有关OpenOffice实现编辑问题

这个我查了很多资料，好像并不能实现在线的编辑，有想法的小伙伴欢迎留言。
