一、前端 vue-pdf

1、下载依赖

安装依赖

npm install vue-pdf

2、封装的组件

封装的vue组件

<template>

二、java使用aspose（付费）

1.引入库

引入依赖(阿里云仓库无此依赖)

 <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-words</artifactId>
            <version>15.12.0</version>
        </dependency>

jar包

加我qq获取：1092705638（记得备注csdn）

2.封装的工具类

封装的工具类

package com.hz.jx.utils.MingWeiUtil;

import com.aspose.words.Document;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;

import java.io.*;

/**
 * Word 转 Pdf 帮助类
 *
 * 备注:需要引入 aspose-words-15.8.0-jdk16.jar
 */
public class PdfUtil {

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

    /**
     * 生成pdf文件
     * @param wordPath 需要被转换的word全路径带文件名
     * @param pdfPath  转换之后pdf的全路径带文件名
     */
    public static void doc2pdf(String wordPath, String pdfPath) {
        // 验证License 若不验证则转化出的pdf文档会有水印产生
        if (!getLicense()) {
            return;
        }
        try {
            long old = System.currentTimeMillis();
            //新建一个pdf文档
            File file = new File(pdfPath);
            FileOutputStream os = new FileOutputStream(file);
            //Address是将要被转化的word文档
            Document doc = new Document(wordPath);
            //全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换
            doc.save(os, SaveFormat.PDF);
            long now = System.currentTimeMillis();
            os.close();
            //转化用时
            System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


    /**
     * 将word文件转成成pdf文件流
     * @param wordPath word文件地址
     * @param outputStream 输出流
     */
    public static void doc2pdfFileStream(String wordPath, OutputStream outputStream) {
        // 验证License 若不验证则转化出的pdf文档会有水印产生
        if (!getLicense()) {
            return;
        }
        try {
            long old = System.currentTimeMillis();
            //Address是将要被转化的word文档
            Document doc = new Document(wordPath);
            //全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换
            doc.save(outputStream, SaveFormat.PDF);
            long now = System.currentTimeMillis();
            outputStream.close();
            //转化用时
            System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

3、付费密钥文件

resouce目录下创建文件license.xml

<License>
    <Data>
        <Products>
            <Product>Aspose.Total for Java</Product>
            <Product>Aspose.Words for Java</Product>
        </Products>
        <EditionType>Enterprise</EditionType>
        <SubscriptionExpiry>20991231</SubscriptionExpiry>
        <LicenseExpiry>20991231</LicenseExpiry>
        <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>
    </Data>
<!--    word转pdf付费密钥-->

总结

后端获取word文件转成pdf文件流，前端接收文件流使用vue-pdf分页展示。

小编也是试了很多这个最好用。
