Java中几种office文档转pdf的方式

Posted 2020-11-15 song.yan

最近公司要做office的文档，搜集了几种office文档转pdf的方式，简单的做下总结

我主要尝试了三种方式：openoffice，aspose，jacob

对他们进行了大文件，小文件，在linux，在windows，转换txt，excel，word，ppt的测试。

一、aspose：这种方式在目前来看应该是最好的，无论是转换的速度还是成功的概率，还支持的文件类型。

（1）使用：

这种方式使用很简单，引入jar包就可以直接使用

代码：

源码，jar包在最后提供

package aspose;

import java.io.*;

import javax.servlet.http.HttpServletRequest;

import com.aspose.cells.Workbook;
import com.aspose.slides.Presentation;
import com.aspose.slides.SaveFormat;
import com.aspose.words.*;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Font;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.Rectangle;
import com.itextpdf.text.pdf.BaseFont;
import com.itextpdf.text.pdf.PdfWriter;

public class AsposeUtil {

    //校验license
    private static boolean judgeLicense() {
        boolean result = false;
        try {
            InputStream is = AsposeUtil.class.getClassLoader().getResourceAsStream("license.xml");
            License aposeLic = new License();
            aposeLic.setLicense(is);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    // 转换
    public static void trans(String filePath, String pdfPath, String type) {
        if (!judgeLicense()) {
            System.out.println("license错误");
        }
        try {
            System.out.println("as开始：" + filePath);
            long old = System.currentTimeMillis();
            File file = new File(pdfPath);
            toPdf(file, filePath, type);
            long now = System.currentTimeMillis();
            System.out.println("完成：" + pdfPath);
            System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }

    private static void toPdf(File file, String filePath, String type) {
        if ("word".equals(type) || "txt".equals(type)) {
            wordofpdf(file, filePath);
        } else if ("excel".equals(type)) {
            exceOfPdf(file, filePath);
        } else if ("ppt".equals(type)) {
            pptofpdf(file, filePath);
        }else{
            System.out.println("暂不支持该类型："+type);
        }
    }

    private static void wordofpdf(File file, String filePath) {
        FileOutputStream os = null;
        Document doc;
        try {
            os = new FileOutputStream(file);
            doc = new Document(filePath);
            doc.save(os, com.aspose.words.SaveFormat.PDF);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                os.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    private static void exceOfPdf(File file, String filePath) {
        FileOutputStream os = null;
        try {
            os = new FileOutputStream(file);
            Workbook wb = new Workbook(filePath);
            wb.save(os, com.aspose.cells.SaveFormat.PDF);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                os.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    private static void pptofpdf(File file, String filePath) {
        FileOutputStream os = null;
        try {
            os = new FileOutputStream(file);
            Presentation pres = new Presentation(filePath);// 输入pdf路径
            pres.save(os, SaveFormat.Pdf);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                os.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }

}

测试代码：

 这里面每一种类型的文档都至少取了三个，主要是为了测试他们对大文件，小文件的支持，从而能在不同的场景更好的选择使用的方式，在本篇文章的最后会将测试的结果贴上

 （2）初次使用遇到的问题：

　　1）我在这种方式的初次尝试中走的最大的一个坑就是：jar包的引入

　　

　　 

　　

上面这三个分别是转换word/txt,excel,ppt的关键代码，在网上找的很多代码可能都是对一种方式的转换，所以SaveFormat也就不会加上包名，所以我在开始就以为是同一个类，怎么调试都不对，最后也是不记得看了哪个博友的博客才注意到这，一定要加上包名，这三个不同包下的类来自三个不同的jar包

 

 2）还有一个很大的坑就是在linux系统上部署测试的时候报了下面的错

 这个问题就查到了一个结果，官方给出的解释是：

 

也就是缺少jar包，可是我检查后发现jar包引入的也没有错误，在第二天找同事帮忙的时候发现，同样的war包使用他的工具可以正常执行转换

很不可思议，我们是在同一台服务器上上传的相同的war包，不一样的就是使用的工具不一样，我用的xshell，他用的sshClient。

我有又测试了一下，第一次访问的时候都会有这个提示

 要求安装xmanager，然后就试了试，安装之后果然就可以了，原因现在也没搞明白，，知道的留言吧（我们经理说可能是依赖xmanager里面的包，只是一种猜测）

3）还有个小问题就是:在linux上使用的时候需要安装字体，不安装会中文乱码，这里不细说，百度很多，操作很简单

4）在测试的过程中有个ppt文件转换失败，目前还没有找到原因，转换失败的文件在最后也会提供在网盘中。。

5）这种方式不支持中文路径，如果转换的文件里面有中文，就会报文件找不到的错误

二，openoffice方式：这种方式在转小文件的时候还是很好用的，在调研的过程中也发现不少公司在实际开发中就是使用的这种方式，我们公司在之前也是用的这种，但是在文件太大的时候转换的时间就会特别的慢，几十分钟的那种。而且这种方式需要依赖openoffice

（1）代码

注:这种方式需要安装openoffice，使用前需要开启openoffice，在转换大文件的时候速度特别的慢。

使用步骤

（1）安装openoffice

（2）开启openoffice

（3）调用代码

package openoffice;

      public static void toPdf(String filePath, String pdfPath) {
          try {
              long old = System.currentTimeMillis();
              System.out.println("open-开始：" + filePath);
              File wordFile = new File(filePath);
            File PDFFile = new File(pdfPath);
            OpenOfficeConnection connection = new SocketOpenOfficeConnection(host, post);
            try {
                connection.connect();
                DocumentConverter converter = getConverter(host, connection);
                converter.convert(wordFile, PDFFile);
                long now = System.currentTimeMillis();
                  System.out.println("open-完成：" + filePath);
                  System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");
            } catch (ConnectException e) {
                System.out.println("获取OpenOffice连接失败...");
                e.printStackTrace();
            }
            finally{
                connection.disconnect();
            }
          } catch (Exception e) {
              System.out.println("转换失败："+filePath);
              e.printStackTrace();
          }
      }
    private static DocumentConverter getConverter(String connectIp, OpenOfficeConnection connection) {
        DocumentConverter converter = "localhost".equals(connectIp) || "127.0.0.1".equals(connectIp)
                || "0:0:0:0:0:0:0:1".equals(connectIp) ? new OpenOfficeDocumentConverter(connection)
                        : new StreamOpenOfficeDocumentConverter(connection);
        return converter;
    }

}

 （2）首次使用遇到的坑

1）看下面的代码，需要提供的openoffice服务器的安装地址以及端口号，需要注ip（有的需要写内网的ip，有的需要写成127.0.0.1，也有的需要写成localhost），具体写成什么形式根据电脑中一个文件的配置，具体的自行百度

2）开启openoffice服务，如果在转换的过程中强制性杀进程，在连接会出现连接拒绝的问题（我在windows上启动的openoffice，使用linux连接时，有一次连接成功，可以正常的转换，但是当时强制性的杀掉了进程，之后再重启，重装都会连接失败，而且linux尝试连接后，本机再去请求连接也会被拒绝，具体的原因还没找到，这种方式被很多公司正式的使用，应该有解决方案），最后是在linux服务器安装了openoffice，在linux也连接自己的服务完成的测试

三、第三种方式是jacob：这种方式使用起来很方便，把dll文件放到jre的bin目录，引入jar包就可以使用，但是它只支持windows系统，而且转换的速度相对aspose方式来讲要慢一些，对于在部署在windows上，对转换速度要求不高的可以使用这种方式。

（1）代码：

1.下载jacob.jar,将jacob.jar导入程序中，把对应的jcob.dll拷贝到system32/SysWOW64目录下,同时也拷贝到对应的jre的bin目录下。

2.编写转换代码

              toPdf(filePath,pdfPath, type);

              long now = System.currentTimeMillis();
              System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");
          } catch (Exception e) {

        }
    }
