尝试插入页脚时，Apache Poi MS word文档变为空白

Question

您好我在java中编写了一个应用程序 它能够创建一个MS word .doc文件 并插入表格，图像和文字

但是，当我尝试在页脚中插入页码时，我遇到了错误 错误：运行应用程序时，整个ms-word文档变为空白

插入页脚的代码：

 public void addPicture(ResumeData resumeData) {
 try {
         document = new CustomXWPFDocument(
                new FileInputStream(
                        new File(


  "C:\\workoutput\\assignment2\\Resume3\\ResumeTables.doc")));
        FileOutputStream fos = new FileOutputStream(new File(


   "C:\\workoutput\\assignment2\\Resume4\\ResumeTables.doc"));
        String id = document.addPictureData(new FileInputStream(new File(


    "C:\\workoutput\\assignment2\\Resume3\\header.jpg")),
                Document.PICTURE_TYPE_JPEG);
        document.createPicture(id,


       document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG),
                640, 94);

String text = "Page1";
XWPFHeaderFooterPolicy policy = document.getHeaderFooterPolicy();
        if (policy == null) {
            policy = new XWPFHeaderFooterPolicy(doc);
        }

        CTP ctP1 = CTP.Factory.newInstance();
        CTR ctR1 = ctP1.addNewR();
        CTText t = ctR1.addNewT();
        t.setStringValue(text);
        XWPFParagraph codePara = new XWPFParagraph(ctP1, document);

        XWPFParagraph[] newparagraphs = new XWPFParagraph[1];
        newparagraphs[0] = codePara;

        policy.createFooter(policy.DEFAULT, newparagraphs);

 }//end of try
 catch(Exception e){
   e.printStackTrace(); 
   }

  }

我一直在谷歌上寻求有关将页脚插入ms-word文档的帮助 但是，网上有关于将页脚插入ms-word

的资源很少

请帮助
