Java后台代码word转pdf文件下载(类库参考)附jar包

word文件中需要转为pdf文件，word中的空格部分被程序后台动态填充，例如：

上图中带有【标】字样的位置，可以被替换为动态数据，最后被导出为pdf文件。

贴一下java工具类代码

所有过程按照下面两个java文件进行即可，1.首先调用Doc2Pdf中的方法。2.返回对应文件名。

Doc2Pdf.java文件

public class Doc2Pdf {public static boolean getLicense() {boolean result = false;try {//  license.xml应放在..\WebRoot\WEB-INF\classes路径下InputStream is = Doc2Pdf.class.getClassLoader().getResourceAsStream("license.xml");License aposeLic = new License();aposeLic.setLicense(is);result = true;} catch (Exception e) {e.printStackTrace();}return result;}public static void doc2pdf(String Address) {if (!getLicense()) {          // 验证License 若不验证则转化出的pdf文档会有水印产生return;}try {long old = System.currentTimeMillis();File file = new File("D:/bb.pdf");  //新建一个空白pdf文档FileOutputStream os = new FileOutputStream(file);Document doc = new Document(Address);                    //Address是将要被转化的word文档doc.save(os, SaveFormat.PDF);//全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换long now = System.currentTimeMillis();System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");  //转化用时} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {Doc2Pdf.doc2pdf("D:/aa.doc");}
}
