记一次文件从Word转为PDF(documents4j和aspose)

时间：2021-10-18 07:40:19

前言:

两种方法:documents4j和aspose

最开始是用documents4j,在本地使用很方便,但是部署到LINUX上面之后,抛出异常,就看了下官方文档,documents4j是使用本地的MS Office应用做的文件格式转换,Linux没有对应的MS Office应用,所以直接就废除.后来改用aspose,在本地也是测试完成,没有问题,但是服务器上就是各种中文乱码(中文小方格),跟之前使用openoffice的乱码虽然不一样,但是还是乱码.不过最终解决了问题.

一、documents4j实现格式转换

需要MS Office,官方并没有说documents4j不支持Linux下运行,但是LINUX确实没安装MS应用,我也没费工夫去研究安装MS,如果谁好了,麻烦告知一下.

依赖

<dependency><groupId>com.documents4j</groupId><artifactId>documents4j-local</artifactId><version>1.1.1</version></dependency><dependency><groupId>com.documents4j</groupId><artifactId>documents4j-transformer-msoffice-word</artifactId><version>1.1.1</version></dependency>

代码

package com.qingyu.transform.utils;import com.documents4j.api.DocumentType;import com.documents4j.api.IConverter;import com.documents4j.job.LocalConverter;import org.junit.jupiter.api.Test;import java.io.*;/*** @ProjectName: transform* @Package: com.qingyu.transform.utils* @ClassName: WordToPdf* @Author: qingyu* @Description:* @Date: /3/19 13:46* @Version: 1.0*/class WordToPdf {/*** 将之前对应的word文件转换成pdf，然后预览pdf文件*/public static String wordToPdf( String suffix ){// 转换之后的pdf文件File inputWord = new File("C:/Users/Administrator/Desktop/测试.docx");File outputFile = new File("C:/Users/Administrator/Desktop/测试.pdf");try {InputStream docxInputStream = new FileInputStream(inputWord);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build();if(suffix.equals("doc")){converter.convert(docxInputStream).as(DocumentType.DOC).to(outputStream).as(DocumentType.PDF).execute();} else if(suffix.equals("docx")){converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();} else if(suffix.equals("txt")){converter.convert(docxInputStream).as(DocumentType.TEXT).to(outputStream).as(DocumentType.PDF).execute();}outputStream.close();} catch (Exception e) {e.printStackTrace();}return null;}public static void main(String[] args) {wordToPdf("docx");}}

二、aspose实现文件转换

依赖

首先aspose是收费软件，pom依赖无法直接下载（反正我是没下载下来），我是通过下载别人分享的链接拿到的jar包。通过Project StraStructure引用进来的，在项目中直接放在lib包下面.

下面的依赖是根据jar包的pom文件写的,不是正确的,不过你可以自己上传到自己的repository中,构建一个pom,然后作为依赖加到项目中

<dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>16.8.0</version></dependency>

代码

/*** @ProjectName: transform* @Package: com.qingyu.transform.utils* @ClassName: Word2PdfUtil* @Author: qingyu* @Description:* @Date: /3/20 10:47* @Version: 1.0*/import com.aspose.words.Document;import com.aspose.words.License;import com.aspose.words.SaveFormat;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import java.io.*;public class Word2PdfUtil {/*** The constant LOG.**/private static final Logger LOG = LoggerFactory.getLogger(Word2PdfUtil.class);/*** 获取license** @return*/private static boolean getLicense() {boolean result = false;try {// 凭证String licenseStr ="<License>\n" +" <Data>\n" +" <Products>\n" +"<Product>Aspose.Total for Java</Product>\n" +"<Product>Aspose.Words for Java</Product>\n" +" </Products>\n" +" <EditionType>Enterprise</EditionType>\n" +" <SubscriptionExpiry>20991231</SubscriptionExpiry>\n" +" <LicenseExpiry>20991231</LicenseExpiry>\n" +" <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>\n" +" </Data>\n" +" <Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>\n" +"</License>";InputStream license = new ByteArrayInputStream(licenseStr.getBytes("UTF-8"));License asposeLic = new License();asposeLic.setLicense(license);result = true;} catch (Exception e) {LOG.error("error:", e);}return result;}/*** Word 2 pdf.** @param pdfFilePath the pdf file path*/public static void word2Pdf( String pdfFilePath) {FileOutputStream fileOS = null;// 验证Licenseif (!getLicense()) {LOG.error("验证License失败！");return;}File inputWord = new File("C:/Users/Administrator/Desktop/测试.docx");try {//此处处理乱码和小方块//如果在本地运行,此处报错,请注释这个这是字体,主要是为了解决linux环境下面运行jar时找不到中文字体的问题FontSettings.getDefaultInstance().setFontsFolders(new String[] {"/usr/share/fonts", "/usr/share/fonts/chinese"}, true);Document doc = new Document(new FileInputStream(inputWord));fileOS = new FileOutputStream(new File(pdfFilePath));// 保存转换的pdf文件doc.save(fileOS, SaveFormat.PDF);} catch (Exception e) {LOG.error("error:", e);} finally {try {if(fileOS != null){fileOS.close();}} catch (IOException e) {LOG.error("error:", e);}}}public static void main(String[] args) {word2Pdf("C:/Users/Administrator/Desktop/测试.pdf");}}
