【java】使用Aspose word将word轉為pdf，并自定義水印

1、依賴jar包 及 license.xml

• 提取碼：790o

2、代碼實作：

public class Word2PdfUtil {

    public static void main(String[] args) {
        doc2pdf("E:\\test.doc",
                "E:\\test.pdf");

    }

    /**
     * word轉pdf 	
     */
    public static void doc2pdf(String inPath, String outPath) {
        
        // 驗證License
        if (!getLicense()) {
            return;
        }
        
        FileOutputStream os = null;
        try {
            System.out.println("開始轉換...");
            
            // 建立一個空白pdf文檔
            File file = new File(outPath); 
            os = new FileOutputStream(file);
            
            //待轉換的檔案，添加水印
            Document doc = new Document(inPath); 
            insertWatermarkText(doc, "我是水印");
            
            //全面支援DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 互相轉換
            doc.save(os, SaveFormat.PDF);
            
            System.out.println("轉換完成...");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (os != null) {
                try {
                    os.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }

        } catch (Exception e) {
            e.printStackTrace();

3、注：如果提示 javaSoft注冊權限問題

打開系統資料庫（regedit），找到HKEY_LOCAL_MACHINE \ SOFTWARE \ JavaSoft，右鍵改權限為完全許可
