JAVA將Word轉成PDF

• 有通過dll擴充套件庫，Jacob的方式，這種方式必須本地安裝了Word，不能跨平臺
• 通過Aspose的方式，該功能是付費版，需要破解，我本地測試Excel有水印，無法去掉，應該是序列號不對，Excel跟Word演算法不一致，無法共用

JAR

下載完畢後如下圖
aspose-cells-8.5.2.jar
aspose-words-15.8.0-jdk16.jar

1.使用mvn install可以安裝到本地maven庫
2.直接將lib包放在src/main/webapp/lib/下面

<!-- word2pdf -->
 

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-words</artifactId>
    <version>15.8.0-jdk16</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/aspose-words-15.8.0-jdk16.jar</systemPath
 
>
</dependency>
<!-- excel2pdf -->
<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-cells</artifactId>
    <version>8.5.2</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/aspose-cells-8.5.2.jar</systemPath
 
>
</dependency>

使用程式碼

public class Office2pdf {

    private static boolean getLicense() {
        boolean result = false;
        try {
            InputStream is = Office2pdf.class.getClassLoader().getResourceAsStream("license.xml"); //  license.xml應放在..\WebRoot\WEB-INF\classes路徑下
            License aposeLic = new License();
            aposeLic.setLicense(is);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    public static void doc2pdf(String wordPath, String pdfPath) {
        if (!getLicense()) {          // 驗證License 若不驗證則轉化出的pdf文件會有水印產生
            return;
        }
        try {
            long old = System.currentTimeMillis();
            File file = new File(pdfPath);  //新建一個pdf文件
            FileOutputStream os = new FileOutputStream(file);
            Document doc = new Document(wordPath);                    //Address是將要被轉化的word文件
            doc.save(os, com.aspose.words.SaveFormat.PDF);//全面支援DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互轉換
            long now = System.currentTimeMillis();
            os.close();
            System.out.println("共耗時：" + ((now - old) / 1000.0) + "秒");  //轉化用時
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * @param excelPath
     * @param pdfPath
     */
    public static void excel2pdf(String excelPath, String pdfPath) {
        if (!getLicense()) {          // 驗證License 若不驗證則轉化出的pdf文件會有水印產生
            return;
        }
        try {
            long old = System.currentTimeMillis();
            Workbook wb = new Workbook(excelPath);// 原始excel路徑
            FileOutputStream fileOS = new FileOutputStream(new File(pdfPath));
            wb.save(fileOS, com.aspose.cells.SaveFormat.PDF);
            fileOS.close();
            long now = System.currentTimeMillis();
            System.out.println("共耗時：" + ((now - old) / 1000.0) + "秒");  //轉化用時
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
