最近因为要用freemarker  生成wrod文件,在转pdf 在线预览后是xml我先把freemarker 生成的文件转成docx在转pdf

doc转docx

XmlDocToDocxUtil类

测试

public static void main(String[] args) {
    String outpath = "F:\\AA.doc";
     String docxPath = XmlDocToDocxUtil.invoke(outpath);
    InputStream source;
    OutputStream target;
    try {
        source = new FileInputStream(docxPath);
        target = new FileOutputStream("E:\\aa.pdf");
        PdfOptions options = PdfOptions.create();
        DocxToPDFConverter converter = new DocxToPDFConverter(source, target, true, true);
        converter.convert();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
