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

技术图片

 

 

 这个问题就查到了一个结果,官方给出的解释是:

 

 

 

 技术图片技术图片

 

 

 

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

技术图片

 

 

 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)

 

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
