将Word或Excel转换成PDF

使用1.jacob的方式进行Word转为PDF
使用Jacob需要因为Jacob的jar包如果是maven的话我这是使用的私服的形式进行引用的。

然后还需要将jacob版本对应的ddl文件放到jdk或jre的bin目录里：

/* 转PDF格式值 */
    private static final int wdFormatPDF = 17;
    /**
     * Word文档转换
     *
     * @param inputFile
     * @param pdfFile
     */
    public static boolean word2PDF(String inputFile, String pdfFile) {
    
        ComThread.InitMTA(true);
        ActiveXComponent app = null;
        Dispatch doc = null;
        try {
    
            app = new ActiveXComponent("Word.Application");// 创建一个word对象
            app.setProperty("Visible", new Variant(false)); // 不可见打开word
            app.setProperty("AutomationSecurity", new Variant(3)); // 禁用宏
            Dispatch docs = app.getProperty("Documents").toDispatch();// 获取文挡属性

            log.info("打开文档 >>> " + inputFile);
            // Object[]第三个参数是表示“是否只读方式打开”
            // 调用Documents对象中Open方法打开文档，并返回打开的文档对象Document
            doc = Dispatch.call(docs, "Open", inputFile, false, true).toDispatch();
            log.info("转换文档 [" + inputFile + "] >>> [" + pdfFile + "]");
            // 调用Document对象的SaveAs方法，将文档保存为pdf格式
            // word保存为pdf格式宏，值为17
            Dispatch.call(doc, "SaveAs", pdfFile, wdFormatPDF);// word保存为pdf格式宏，值为17

            return true;
        } catch (Exception e) {
    
            e.printStackTrace();
            log.info("========Error:文档转换失败：" + e.getMessage());
        } finally {
    
            Dispatch.call(doc, "Close", false);
            log.info("关闭文档");
            if (app != null)
                app.invoke("Quit", new Variant[] {
    });
            // 如果没有这句话,winword.exe进程将不会关闭
            ComThread.Release();
            ComThread.quitMainSTA();
        }
        return false;
    }

使用aspose将Word或Excel转为PDF
将授权文件放到resources目录下
导入aspose-words和asopse-cells包这里使用私服

license.xml如下：

接下来是工具类

package com.ly.sys.utils;

import com.aspose.words.*;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;


public class Word2PdfAsposeUtil {
    
    //获取aspose证书，防止生成的pdf有水印
    public static boolean getLicense() {
    
        boolean result = false;
        try {
    
            InputStream is = Word2PdfAsposeUtil.class.getClassLoader().getResourceAsStream("license.xml");
            License aposeLic = new License();
            aposeLic.setLicense(is);
            result = true;
        } catch (Exception e) {
    
            e.printStackTrace();
        }
        return result;
    }

    /**

     */
    public static String doc2pdf(String sourceDoc, String targetPdf) throws IOException {
    
        if (!getLicense()) {
    
            // 验证License 若不验证则转化出的pdf文档会有水印产生
            return "failed:can't find aspose license";
        }
        FileOutputStream os = null;
        try {
    
            long start = System.currentTimeMillis();
            //新建一个空白pdf文档
            File file = new File(targetPdf);
            os = new FileOutputStream(file);
            Document doc = new Document(sourceDoc);
            doc.save(os, SaveFormat.PDF);
            long end = System.currentTimeMillis();
            System.out.println("word转pdf共耗时：" + ((end - start) / 1000.0) + "秒");
        } catch (Exception e) {
    
            e.printStackTrace();
        } finally {
    
            if (os != null) {
    
                os.close();
            }
        }
        return "successed";
    }

}

public static void main(String[] args) throws IOException {

        Word2PdfAsposeUtil.doc2pdf("D:/TWO.docx", "D:/TWO1.pdf");
    }

转为Excel
